Claim:
A lifting mechanism of a vehicle seat for adjusting a seating height position of the vehicle seat, the lifting mechanism comprising: a lifter link having a first side that is rotatably shaft-supported with respect to a floor-side member provided on a vehicle floor and a second side that rotatably shaft-supports a frame member of a seating-side configuring part for seating; and a stopper link having a first side that is rotatably shaft-supported with respect to the floor-side member and a second side that is loosely fitted in a long hole defined in the lifter link, wherein a rotation of the lifter link in a rear direction due to the seating-side configuring part applying load toward a rear side of the seat is restrained by a loosely fitted portion of the stopper link contacting an inner circumferential part of the long hole, wherein a rotation of the lifter link in a front direction due to the seating-side configuring part applying load toward a front side of the seat is restrained by a restraining contact part provided to the lifter link contacting a stopper part provided to the floor-side member, and wherein a rear-side end portion of the restraining contact part, which contacts the stopper part, is provided at a further outer side in a rotationally radial direction than a position of a front-side end portion of the long hole, with respect to a rotatable shaft support point of the first side of the lifter link.
