  • VEHICLE DOOR
    Publication number: 20230323708
    Abstract: A vehicle door maintains a pulling amount of a release cable without increasing the size of a cable pulling member, or degrading ease of operation of a door handle. The door includes a handle gripped by a user; a handle arm turned about a hinge pin with operation of the handle; a crank plate turned about a hinge pin with turning of the handle arm, thus pulling a release cable; and a latch device that releases a door lock when the release cable is pulled. The crank plate pulls the release cable by causing a contact surface, which comes into contact with the release cable, to move with turning of the crank plate. The contact surface is formed such that a distance from the hinge pin to the contact surface increases as the contact surface moves in a direction opposite to a turning direction when opening the door.
