Stopper device

A stopper device configured to be disposed between a fixed member and a movable member configured to move toward and away from the fixed member, comprising:

• a base member configured to be fixed to one of the fixed member and the movable member;
• a shaft member having an abutting portion configured to abut on another of the fixed member and the movable member, and housed in the base member so as to be ascendable and descendable in a rotation restricted state;
• a rotary member mounted so as to be rotatable and not to be ascendable and descendable with respect to the base member;
• a gear member disposed inside the rotary member in a state where rotation is restricted with respect to the rotary member;
• a temporary fixing portion disposed between the shaft member and the gear member and configured to temporarily fix the gear member to the shaft member;
• and
• a cam mechanism disposed between the base member and the gear member, including a cam slope and a cam abutting portion configured to abut on the cam slope, and configured to cause the gear member to ascend with respect to the rotary member by rotation of the rotary member in a predetermined direction, wherein
• when the gear member rotates in conjunction with the rotation of the rotary member, the shaft member is ascended by the cam mechanism while maintaining a temporary fixing state of the shaft member by the temporary fixing portion, and
• 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.
