PROBLEM TO BE SOLVED: To detect the state of a housing without providing an exclusive magnet. SOLUTION: A state detector of the housing is provided with: a plurality of housings (1, 2); connection mechanisms 11, 12 and 13 which connect the plurality of housings (1, 2) so as to be relatively and freely movable; and connection mechanisms 14, 15 and 16 which are connected between the plurality of housings (1, 2) so as to assist relative movement. In the state detector of the housing, at least a part of the connection mechanisms 14, 15 and 16 is constituted of magnetic bodies, and the state detector of the housing is provided with a magnetic sensor 17 which detects the magnetism of the magnetic bodies in accordance with the movement of the connection mechanisms 14, 15 and 16 by the relative movement of the plurality of housings (1, 2). Specifically, the state detector comprises: a spring member 14 which assists the relative movement of the plurality of housings (1, 2); and fixing pins 15 and 16 which attach the sprint member 14 to the housings (1, 2).
