Abstract
A stopper device includes: a base member; a shaft member; a rotary member; a gear member disposed inside the rotary member; a temporary fixing portion configured to temporarily fix the gear member to the shaft member; and a cam mechanism including a cam slope and a cam abutting portion. When the gear member rotates in conjunction with a rotation of the rotary member, the shaft member is ascended by the cam mechanism. The gear member further includes a permanent fixing portion configured to restrict an ascending and descending motion of the shaft member in an ascended state.
