摘要

A lifting mechanism (30) of a vehicle seat (10) for adjusting a seating height position of the vehicle seat (10) is provided. The lifting mechanism (30) includes a lifter link (41) having one side that is rotatably shaft-supported to a floor-side member provided on a vehicle floor (F) and the other side that rotatably shaft-supports a frame member of a seating-side configuring part for seating; and a stopper link (31) having one side that is rotatably shaft-supported to the floor-side member and the other side that is loosely fitted in a long hole formed in the lifter link (41). A rotation of the lifter link (41) in a rear direction is restrained by a loosely fitted portion of the stopper link (31) contacting an inner circumferential part of the long hole. A rotation of the lifter link (41) in a front direction is restrained by a restraining contact part (48) provided to the lifter link contacting a stopper part (25) provided to the floor-side member. The restraining contact part (48) 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 one side of the lifter link (41).
