Abstract:
1. A seat slide apparatus for a vehicle, comprising: a lower rail adapted to be fixed to a vehicle floor; an upper rail adapted to be fixed to the seat for moving relative to the lower rail; a lock lever rotatably connected to the upper rail and configured to be engaged with the lower rail for selectively restricting a movement of the upper rail relative to the lower rail; a first biasing member for elastically retaining the lock lever at a predetermined initial position where the movement of the upper rail relative to the lower rail is restricted; an operational lever rotatably connected to the upper rail and operationally connected to the lock lever, the operational lever having an end portion which is configured to transmit an operational force of the operational lever to the lock lever for canceling the restriction of the movement of the upper rail relative to the lower rail in response to a rotational operation of the operational lever; a second biasing member for elastically retaining the operational lever at a predetermined initial position; and a cushioning member provided at one of the operational lever and the lock lever, the cushioning member being configured to contact the other of the operational lever and the lock lever for restricting a contact of the end portion of the operational lever with the lock lever at an initial stage of the rotational operation of the operational lever and being configured to allow a contact of the end portion of the operational lever with the lock lever when canceling the restriction of the movement of the upper rail relative to the lower rail by the lock lever in response to the rotational operation of the operational lever.
