A seat slide apparatus for a vehicle, comprising: a first rail; a second rail slidably movable relative to the first rail; a lock member restricting a movement of the second rail relative to the first rail; a memory member movably supported within an inner void that is formed between the first rail and the second rail in a longitudinal direction of the first rail, the memory member being prevented from moving by an engagement with the first rail; a holding member fixed to the second rail and holding the memory member so that the memory member is movable along with the second rail in a condition where the restricted movement of the second rail relative to the first rail by the lock member is released in accordance with an operation of an operation handle, the holding member holding the memory member so as to maintain the engagement between the memory member and the first rail in a condition where the restricted movement of the second rail relative to the first rail by the lock member is released in accordance with a forward tilting movement of a seat back of a seat configured to be fixed to the second rail, a first stopper member positioned at one side of the memory member in the moving direction of the second rail relative to the first rail and fixed to the first rail; and a second stopper member fixed to the second rail and positioned at the other side of the memory member in the moving direction of the second rail relative to the first rail and fixed to the second rail, the second stopper member preventing the second rail from moving toward one side in the moving direction of the second rail relative to the first rail in a condition where the memory member is sandwiched between the first stopper member and the second stopper member. a first rail; a second rail slidably movable relative to the first rail; a lock member restricting a movement of the second rail relative to the first rail; a memory member movably supported within an inner void that is formed between the first rail and the second rail in a longitudinal direction of the first rail, the memory member being prevented from moving by an engagement with the first rail; a holding member fixed to the second rail and holding the memory member so that the memory member is movable along with the second rail in a condition where the restricted movement of the second rail relative to the first rail by the lock member is released in accordance with an operation of an operation handle, the holding member holding the memory member so as to maintain the engagement between the memory member and the first rail in a condition where the restricted movement of the second rail relative to the first rail by the lock member is released in accordance with a forward tilting movement of a seat back of a seat configured to be fixed to the second rail, a first stopper member positioned at one side of the memory member in the moving direction of the second rail relative to the first rail and fixed to the first rail; and a second stopper member fixed to the second rail and positioned at the other side of the memory member in the moving direction of the second rail relative to the first rail and fixed to the second rail, the second stopper member preventing the second rail from moving toward one side in the moving direction of the second rail relative to the first rail in a condition where the memory member is sandwiched between the first stopper member and the second stopper member.
