Rubber stopper
The present invention provides a rubber stopper that can set a shape suitable for mounting and set a desired stopper characteristic. Specifically, a holding fitting 3 fastened to one member by means of bolting is provided. A rubber section 4 that abuts against the other member is held by the holding fitting 3 . The holding fitting 3 has a partition wall 8 to divide between a peripheral edge of a bolt hole 7 and a holding section 9 that holds the rubber section 4 . A rubber side abutment surface 12 in the rubber section 4 protrudes from a top of the partition wall 8 . A bored section 13 is formed near the partition wall 8 of the rubber section 4 . The bored section 13 increases durability of the rubber section 4 . A size of the rubber stopper 1 is reduced.
1. A rubber stopper for limiting relative displacement of a plurality of members, comprising:
a holding fitting fastened by means of bolting to one of the plurality of members; and

in the rubber section, a rubber side abutment surface that abuts against said another member is provided to protrude from a top of the partition wall, and a bored section is formed near the partition wall;
wherein said bored section of said rubber section that is formed near said partition wall is a recess in said rubber side abutment surface adjacent said partition wall configured such that upon compressing said rubber section by pressure of said another member against said rubber side abutment surface, said rubber section deforms into said recess such as to reduce local stress of the rubber section restrained by said partition wall.
2. The rubber stopper according to claim 1 , wherein the rubber side abutment surface is formed to be brought into surface contact with a portion of said another member against which the rubber side abutment surface abuts.
3. The rubber stopper according to claim 1 , wherein a fitting side abutment surface that abuts against said another member to limit deformation of the rubber section is formed in the holding fitting, and the fitting side abutment surface is formed to be brought into surface contact with a portion of said another member against which the fitting side abutment surface abuts.
4. The rubber stopper according to claim 1 , wherein said partition wall is configured to extend around a portion of said peripheral edge of said bolt hole.
5. The rubber stopper according to claim 4 , wherein said partition wall is configured to curve around a portion of said peripheral edge of said bolt hole.
6. The rubber stopper according to claim 5 , wherein said bored section is formed in said rubber section adjacent the portion of said partition wall that curves around the portion of said peripheral edge of said bolt hole.
7. The rubber stopper according to claim 6 , wherein said bored section is formed into a curved shape.
8. The rubber stopper according to claim 7 , wherein said bored section is formed into a semi-oval shape.
9. The rubber stopper according to claim 6 , wherein said bored section has a bottom that is set to a depth that is higher than a top of the partition wall and a width that is narrower than that of the partition wall.
10. The rubber stopper according to claim 4 , wherein said bored section is formed in said rubber section adjacent the portion of said partition wall that extends around the portion of said peripheral edge of said bolt hole.
11. The rubber stopper according to claim 10 , wherein said bored section is formed into a curved shape.
12. The rubber stopper according to claim 11 , wherein said bored section is formed into a semi-oval shape.
13. The rubber stopper according to claim 11 , wherein said bored section has a bottom that is set to a depth that is higher than a top of the partition wall and a width that is narrower than that of the partition wall.
14. A rubber stopper for limiting relative displacement of a plurality of members, comprising:
a holding fitting fastened by means of bolting to one of the plurality of members; and
a rubber section that is held by the holding fitting and abuts against another of the plurality of members,
wherein the holding fitting has a partition wall that divides between a peripheral edge of a bolt hole through which a fastening bolt is inserted and a holding section that holds the rubber section,
in the rubber section, a rubber side abutment surface that abuts against said another member is provided to protrude from a top of the partition wall, and a bored section is formed near the partition wall,
wherein the rubber stopper is fastened to a bogie side of a railway vehicle by a bolt so that the rubber side abutment surface abuts against a link rod that connects the bogie side and a vehicle body to transmit forward and rearward forces to limit lateral movement of the link rod relative to the bogie side and limit lateral movement of the vehicle body side.
15. A rubber stopper for limiting relative displacement of a plurality of members, comprising:
a holding fitting fastened by means of bolting to one of the plurality of members; and
a rubber section that is held by the holding fitting and abuts against another of the plurality of members,
wherein the holding fitting has a partition wall that divides between a peripheral edge of a bolt hole through which a fastening bolt is inserted and a holding section that holds the rubber section,
in the rubber section, a rubber side abutment surface that abuts against said another member is provided to protrude from a top of the partition wall, and a bored section is formed near the partition wall,
wherein the rubber side abutment surface is formed to be brought into surface contact with a portion of said another member against which the rubber side abutment surface abuts,
wherein the rubber stopper is fastened to a bogie side of a railway vehicle by a bolt so that the rubber side abutment surface abuts against a link rod that connects the bogie and a vehicle body side to transmit forward and rearward forces to limit lateral movement of the link rod relative to the bogie side and limit lateral movement of the vehicle body side.
16. A rubber stopper for limiting relative displacement of a plurality of members, comprising:
a holding fitting fastened by means of bolting to one of the plurality of members; and
a rubber section that is held by the holding fitting and abuts against another of the plurality of members,
