A lifter device includes a pinion gear and a rotation control device that is configured to control rotation of the pinion gear. The rotation control device includes a rotation shaft, a support member, a rotation driving mechanism, and a lock mechanism. The rotation drive mechanism includes a feed gear, and a plurality of feed pawls. The lock mechanism is configured to release locking of the rotation shaft until any one of the feed pawls meshes with the feed gear when an operation handle is operated. A plurality of the feed pawls are provided with respect to either operation direction on a seat lifting side or lowering side of the operation handle, and one of the feed pawls meshes with the feed gear when at least one of the others of the feed pawls does not mesh with the gear.
