  • Publication number: 20230332445
    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.

  • Patent number: 8469412
    Abstract: A door handle device is provided with: a door handle 9 by which the door of a vehicle can be opened and closed; a mounting bracket 11 for supporting the door handle 9 through a supporting shaft 15 so that the door handle can be swung in the back-and-forth direction with respect to the door 3 of the vehicle; and a switch unit 13, which is arranged between the door handle 9 and the mounting bracket 11, which generates an electric signal for locking and unlocking a door lock provided in the door of the vehicle. A contact portion (an engaging groove 27), with which the supporting shaft 15 comes into contact, is formed in the switch unit 13. When the supporting shaft 15 is inserted into a handle shaft insertion hole 9b and a bracket shaft insertion hole 11a so that the supporting shaft 15 can be engaged with the holes by an engaging grove 27, the switch unit is fixed to the mounting bracket.
