Claims

[Claims for Utility Model Registration] (1) The frame body is rotatably supported via a fulcrum member so that the dynamic moment becomes zero, one end faces the detected part with a gap, and the other end faces the detected part with a gap. an operating lever having an end that operates the switch; and an operating lever that is rotatably supported by the operating lever at a position different from the fulcrum member so that the dynamic moment becomes zero, and one end that is located in the gap of the operating lever. The lock lever is provided with a groove located in the support member and facing the detected portion, and the lock lever is provided with a groove and a protrusion that engages with the groove, and while the detected portion is displaced by the gap, the operating lever is A detection device characterized by locking rotation. (2) The detection device according to claim 1 of the utility model registration claim, in which a notch is provided at one end of the operating lever. (3) The detection device according to claim 2 of the utility model registration, wherein one end of the lock lever is provided with a bent portion that can be inserted into the notch of the fulcrum member.
