Antivibration device

1. An antivibration device comprising:

a mount body having a first attached member attached to a vibration source side, a second attached member attached to a vehicle body frame side, and an antivibration base body formed of a rubber elastic body and interconnecting the first attached member and the second attached member;

a connecting member fixedly fastened on one side to the first attached member and fixedly fastened on the other side to the vibration source side;

a retainer member retaining the second attached member; and

a displacement restriction member disposed on the retainer member and surrounding the one side of the connecting member, the displacement restriction member being formed with an insertion hole for enabling a bolt to pierce which fixedly fastens the connecting member to the first attached member, wherein

the first attached member includes an upright portion upstanding toward the displacement restriction member,

when the second attached member is retained on the retainer member with the antivibration base body being precompressed, the interposition of the upright portion enables a space into which the one side of the connecting member is insertable, to be formed between the first attached member and the displacement restriction member, and

in the state that the one side of the connecting member is fixedly fastened to the first attached member, a gap between the upright portion and the displacement restriction member is set to a larger dimension than a gap between the connecting member and the displacement restriction member.

2. The antivibration device according to claim 1 , further comprising a covering rubber portion formed of a rubber elastic body connected to the antivibration base body and covering at least an upright end surface of the upright portion.

3. The antivibration device according to claim 1 , wherein

the upright portion includes an abutting wall on which an inserted distal end side of the connecting member inserted into the space between the first attached member and the displacement restriction member is brought into abutment, and

when the inserted distal end side of the connecting member is brought into abutment on the abutting wall, the connecting member is disposed at a position being able to be fastened relative to the first attached member.

4. The antivibration device according to claim 3 , further comprising:

a protrusion protruding from one of the inserted distal end side of the connecting member and the abutting wall; and

a receiving portion formed on the other of the inserted distal end side of the connecting member and the abutting wall for receiving the protrusion to be engaged,

wherein when the inserted distal end side of the connecting member is brought into abutment on the abutting wall, the protrusion is received in the receiving portion, and the connecting member is positioned relative to the first attached member.

5. The antivibration device according to claim 4 , wherein the upright portion includes a pair of facing walls disposed to face lateral surfaces of the connecting member inserted into the space between the first attached member and the displacement restriction member.

6. The antivibration device according to claim 5 , wherein the upright portion has the abutting wall connected to the facing walls.

7. The antivibration device according to claim 4 , further comprising:

a stopper rubber formed of a rubber elastic body and mounted on the connecting member, wherein

the protrusion is protruded from the inserted distal end side of the connecting member and the receiving portion is formed on the abutting wall, and

the stopper rubber includes a hook portion formed to be engageable with the protrusion.

8. The antivibration device according to claim 7 , wherein the hook portion is put between the connecting member and the abutting wall.

9. An antivibration device comprising:

a mount body having a first attached member attached to a vibration source side, a second attached member attached to a vehicle body frame side, and an antivibration base body formed of a rubber elastic body and interconnecting the first attached member and the second attached member;

a connecting member fixedly fastened on one side to the first attached member and fixedly fastened on the other side to the vibration source side;

a retainer member retaining the second attached member; and

a displacement restriction member disposed on the retainer member and surrounding the one side of the connecting member, the displacement restriction member being formed with an insertion hole for enabling a bolt to pierce which fixedly fastens the connecting member to the first attached member, wherein

the first attached member includes an upright portion upstanding toward the displacement restriction member,

when the second attached member is retained on the retainer member with the antivibration base body being precompressed, the interposition of the upright portion enables a space into which the one side of the connecting member is insertable, to be formed between the first attached member and the displacement restriction member,

wherein the upright portion includes an abutting wall on which an inserted distal end side of the connecting member inserted into the space between the first attached member and the displacement restriction member is brought into abutment, and

when the inserted distal end side of the connecting member is brought into abutment on the abutting wall, the connecting member is disposed at a position being able to be fastened relative to the first attached member.

10. The antivibration device according to claim 9 , further comprising a covering rubber portion formed of a rubber elastic body connected to the antivibration base body and covering at least an upright end surface of the upright portion.

11. The antivibration device according to claim 10 , wherein in the state that the one side of the connecting member is fixedly fastened to the first attached member, a gap between the upright portion and the displacement restriction member is set to a larger dimension than a gap between the connecting member and the displacement restriction member.

12. The antivibration device according to claim 9 , further comprising:

a protrusion protruding from one of the inserted distal end side of the connecting member and the abutting wall; and

a receiving portion formed on the other of the inserted distal end side of the connecting member and the abutting wall for receiving the protrusion to be engaged,

wherein when the inserted distal end side of the connecting member is brought into abutment on the abutting wall, the protrusion is received in the receiving portion, and the connecting member is positioned relative to the first attached member.

13. The antivibration device according to claim 12 , wherein the upright portion includes a pair of facing walls disposed to face lateral surfaces of the connecting member inserted into the space between the first attached member and the displacement restriction member.

14. The antivibration device according to claim 13 , wherein the upright portion has the abutting wall connected to the facing walls.

15. The antivibration device according to claim 12 , further comprising:

a stopper rubber formed of a rubber elastic body and mounted on the connecting member, wherein

the protrusion is protruded from the inserted distal end side of the connecting member and the receiving portion is formed on the abutting wall, and

the stopper rubber includes a hook portion formed to be engageable with the protrusion.

16. The antivibration device according to claim 15 , wherein the hook portion is put between the connecting member and the abutting wall.
