震感知器。[Claims for Utility Model Registration] A support member is fitted into the detection box, a detection body is suspended from the support member by magnetic force, and one end of the detection body is supported in the middle of the detection box by the side wall of the detection box. In the device that senses an earthquake by loosening the sensing plates together and displacing the sensing plates when the sensing body falls,
The detection plate has a two-part structure consisting of a letter-shaped member, has a notch in the tip portion facing the detection body of the detection plate so as to surround the detection body, and is rotatably supported at an L-shaped bent part. A falling weight seismic sensor is further characterized in that predetermined locations of the detection plate approximately equidistant from the rotatable support point are interconnected.
