。[Claims for Utility Model Registration] A link member that is to be rotated by a predetermined angle around one axis is provided with a long hole extending away from the center of rotation, and a locking member that engages with the long hole of the link member is provided. A drive arm provided with a dowel pin is provided to be rotatable about an axis substantially parallel to the rotation axis of the link member, and the rotational movement of the drive arm is transmitted to the link member. In the link mechanism configured to rotate a member, the engaging pin of the drive arm slides into contact with the link member when the link member is rotated in a direction in which the intersecting angle with the drive arm becomes smaller. A protrusion having an inclined side at a predetermined angle is provided at the inner edge of the elongated hole, and the link member is held at a predetermined rotational position in an engaged state in which the engagement pin passes through the protrusion. A link mechanism having a return prevention function, characterized in that
