Abstract:
1. A seat slide apparatus for a vehicle, comprising: an upper rail supporting a seat at an upper side and including an inner void extending in an extending direction of the upper rail; a lower rail supporting the upper rail to be movable relative to the lower rail; a lock mechanism configured to restrict a relative movement of the upper rail relative to the lower rail and including a lock lever, the lock lever being supported by the upper rail and including an engaging portion that moves within the inner void to be engageable and disengageable relative to an engaged portion formed at the lower rail; and an unlock operation inhibition apparatus including a mass member arranged at the inner void of the upper rail, a moving axis forming member forming a moving axis on which the mass member moves at the inner void along the extending direction of the upper rail, and a restriction portion inhibiting a movement of the mass member on the moving axis, the unlock operation inhibition apparatus restricting the engaging portion from moving to disengage from the engaged portion by the movement of the mass member on the moving axis to a position at which the mass member interferes with the lock lever in a case where a collision load greater than a retraining force specified for the restriction portion is input.
