A seat slide apparatus for a vehicle includes a first rail, a second rail, a lock member, a memory member, a first holding member 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, and a second holding member 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. The first holding member integrally includes a body portion and a memory member holding portion so as to sandwich the memory member in a state where the body portion engages with the front end portion of the memory member.
