Seat slide apparatus for vehicle

A seat slide apparatus for a vehicle includes a first rail (3), a second rail (4), a lock member (26), a memory member (30), a first holding member (50) holding the memory member to move integrally with the second rail in a state where a restriction of the relative movement between the first rail and the second rail is released on a basis of an operation handle (6), and a second holding member (60) holding the memory member so that the engagement of the memory member with the first rail is maintained in a state where the restriction of the relative movement is released in association with a forward folding operation of a seat back (8). The first holding member integrally includes a body portion (51, 52) and a memory member holding portion (53) so as to sandwich the memory member in a state where the body portion engages with a front end portion of the memory member.
