Lifter device
A lifter device includes: an output shaft; a support member supporting the output shaft; an input member coupled to an operation handle; a feed portion transmitting forward and reverse rotation of the input member to the output shaft; a lock portion locking the rotation of the output shaft; and a friction generating portion applying a frictional force to the rotation of the output shaft. A rotating cam of the friction generating portion is a switching structure of switching to: a friction-suppression state when the operation handle is in a neutral position and when the operation handle is turned from the neutral position in a direction of raising the seat; and a friction-on state when the operation handle is turned from the neutral position in a direction of lowering the seat. In the friction-on state, a rotating member is pressed against a fixed member and friction is generated.
