  • Publication number: 20220194188
    Abstract: A handle device for a vehicle includes a handle body, a latch release lever, a door latch device, an electric actuator and a push portion forming member. The handle body moves between an initial position, a pop-up position and to a latch operation position. The door latch device is released by the latch release lever rotating to a latch release position. The push portion forming member moves from an initial corresponding position to a latch operation corresponding position and has a lever push portion to, when the push portion forming member is at the latch operation corresponding position, rotate the latch release lever to the latch release position. The push portion forming member has a restriction wall to prevent, when the push portion forming member is between the initial corresponding position and a pop-up corresponding position, the latch release lever from rotating toward the latch release position.

  • Publication number: 20210381284
    Abstract: A door handle device for a vehicle includes a handle base including an inertia stopper and an operation handle including a stopper protruding portion. The operation handle is movable from an initial position to a use position and to a latch operation position. The inertia stopper has two stopper surfaces and is to rotate from a standby position to a regulation position due to inertia when a collision force is applied to the vehicle. The stopper protruding portion includes a first stopper to, when the operation handle is at the initial position, limit a movement of the operation handle toward the use position by abutting against one of the stopper surfaces, and a second stopper to, when the operation handle is at the use position, limit the movement of the operation handle toward the latch operation position by abutting against another one of the stopper surfaces.
