る。[0004] In particular, the operation of a door opening / closing lever has become a problem particularly in the opening / closing operation of a door. That is, as described above, the rotation angle of the door opening / closing lever is usually set to about 30 °, but this setting is not necessarily easy for the elderly and the disabled to handle. As a result, for example, even if an elderly person and a handicapped person are trapped in a room, it may become extremely difficult to escape on their own, and safety cannot be ensured. Therefore, there is an increasing demand for the development of a lock device that can open and close a door with a slight operation.

る。[0004] In particular, the operation of a door opening / closing lever has become a problem particularly in the opening / closing operation of a door. That is, as described above, the rotation angle of the door opening / closing lever is usually set to about 30 °, but this setting is not necessarily easy for the elderly and the disabled to handle. As a result, for example, even if an elderly person and a handicapped person are trapped in a room, it may become extremely difficult to escape on their own, and safety cannot be ensured. Therefore, there is an increasing demand for the development of a lock device that can open and close a door with a slight operation.
