Abstract

An inside handle device includes a handle case, and a handle lever rotatably supported by the handle case. The handle lever is inserted into the handle case along a rotation axis of the handle lever with respect to the handle case. The handle case includes a case main body into which the handle lever is inserted, and a coming-off prevention member configured to restrict a movement of the handle lever in a direction along the rotation axis and to prevent the handle lever from coming off the case main body. The coming-off prevention member is coupled to the case main body. The coming-off prevention member is configured to be displaceable between an assembling position at which the handle lever is prevented from coming off the case main body and an unfolded position at which the coming-off prevention member is unfolded from the assembling position.

Claims (58)

1. An inside handle device comprising:

a handle case; and

a handle lever rotatably supported by the handle case,

wherein the handle lever is inserted into the handle case along a rotation axis of the handle lever with respect to the handle case,

wherein the handle case includes

a case main body into which the handle lever is inserted,

a coming-off prevention member configured to restrict a movement of the handle lever in a direction along the rotation axis and to prevent the handle lever from coming off the case main body, and

a hinge portion for coupling the coming-off prevention member to the case main body,

wherein the hinge portion is configured such that the coming-off prevention member is displaceable between an assembling position at which the handle lever is prevented from coming off the case main body and an unfolded position at which the coming-off prevention member is unfolded from the assembling position.

2. An inside handle device comprising:

a handle case; and

a handle lever rotatably supported by the handle case,

wherein the handle lever is inserted into the handle case along a rotation axis of the handle lever with respect to the handle case,

wherein the handle case includes

a case main body into which the handle lever is inserted, and

a coming-off prevention member configured to restrict a movement of the handle lever in a direction along the rotation axis and to prevent the handle lever from coming off the case main body,

wherein the coming-off prevention member is coupled to the case main body,

wherein the coming-off prevention member is configured to be displaceable between an assembling position at which the handle lever is prevented from coming off the case main body and an unfolded position at which the coming-off prevention member is unfolded from the assembling position,

wherein the handle case further includes a cable holding portion that couples the case main body and the coming-off prevention member,

wherein the cable holding portion includes

a fixing portion formed integrally with the case main body,

a cap portion configured to engage with the fixing portion, and

a hinge portion configured to couple the cap portion to the fixing portion so as to be unfoldable, and

wherein the coming-off prevention member is formed integrally with the cap portion.

3. An inside handle device comprising:

a handle case; and

a handle lever rotatably supported by the handle case,

wherein the handle lever is inserted into the handle case along a rotation axis of the handle lever with respect to the handle case,

wherein the handle case includes

a case main body into which the handle lever is inserted, and

a coming-off prevention member configured to restrict a movement of the handle lever in a direction along the rotation axis and to prevent the handle lever from coming off the case main body,

wherein the coming-off prevention member is coupled to the case main body,

wherein the coming-off prevention member is configured to be displaceable between an assembling position at which the handle lever is prevented from coming off the case main body and an unfolded position at which the coming-off prevention member is unfolded from the assembling position,

wherein the handle lever is provided with a boss insertion hole,

wherein the case main body is configured to be inserted into the boss insertion hole, and includes a boss in which a groove is formed at a distal end of the boss, and

wherein the coming-off prevention member includes a locking portion configured to be locked to the groove.

4. The inside handle device according to claim 2 , further comprising:

a cable configured to transmit a force between the handle lever and a door lock device,

wherein the cable is sandwiched between the fixing portion and the cap portion when the cap portion is engaged with the fixing portion.

5. The inside handle device according to claim 2 ,

wherein the handle case is an integrally molded product in which the case main body, the cable holding portion, and the coming-off prevention member are integrally molded via a connecting piece provided on the hinge portion, and

wherein the connecting piece is configured to be broken when the cap portion is rotated around the hinge portion.

6. The inside handle device according to claim 2 ,

wherein the handle lever is provided with a boss insertion hole,

wherein the case main body is configured to be inserted into the boss insertion hole, and includes a boss in which a groove is formed at a distal end of the boss, and

wherein the coming-off prevention member includes a locking portion configured to be locked to the groove.

7. The inside handle device according to claim 6 ,

wherein the coming-off prevention member includes

a first arm portion including the locking portion at a distal end of the first arm portion, and

a second arm portion connecting the first arm portion and the cap portion to each other.

8. The inside handle device according to claim 7 ,

wherein the first arm portion has flexibility.

9. The inside handle device according to claim 6 , further comprising:

a cable configured to transmit a force between the handle lever and a door lock device,

wherein the cable is sandwiched between the fixing portion and the cap portion when the cap portion is engaged with the fixing portion.

10. The inside handle device according to claim 6 ,

wherein the handle case is an integrally molded product in which the case main body, the cable holding portion, and the coming-off prevention member are integrally molded via a connecting piece provided on the hinge portion, and

wherein the connecting piece is configured to be broken when the cap portion is rotated around the hinge portion.
