This attaching/detaching device (1) has: an elastic member (3) having bent parts, which is disposed at a default position on a support member (2) while kept in an elastically deformed state with an elastic force acting thereon; a first fulcrum (21) and a second fulcrum (22) which are disposed on the support member (2) so as to maintain the elastic member (3) in the elastically deformed state while allowing the elastic member (3), upon receiving an external force, to rotate on the support member (2); a regulation part (23) for regulating the rotatable range of the elastic member (3) on the support member (2); and an external force input part (32) to which a moment for rotating the elastic member (3) is input as an external force. The elastic member (3) is slidably supported at the first fulcrum (21) and/or the second fulcrum (22). The regulation part (23) allows the elastic member (3) to rotate only in a direction in which the amount of elastic deformation of the elastic member (3) increases. |
