Abstract

To enable switching between preventing and allowing the rotation of a crescent lock, without using a mechanism driven by electrical power.SOLUTION: A first stopper 131 can be displaced between a first position that prevents the rotation of a crescent lock 11 for locking / unlocking an opening / closing body and a second position that allows the rotation, and includes a magnetized portion. A first housing 121 accommodates at least a portion of the first stopper 131. A second housing 122 is attachable to and detachable from the first housing 121. A magnet 14 is accommodated in the second housing 122. When the second housing 122 is attached to the first housing 121, the first stopper 131 is displaced to the second position. When the second housing 122 is removed from the first housing 121, the first stopper 131 is made displaceable to the first position.SELECTED DRAWING: Figure 7
