Abstract

PURPOSE:To intend to prevent a malfunction by an external vibration together with a reduction of power and a miniaturization by constructing it to hold the normal status and the tripped status by permanent magnets. CONSTITUTION:Permanent magnets 231 and 232 are set at both sides of a frame 21, and are held at each of opposed side pieces 122a of a collar 122. Further, a front frame 24 made of nonmagnetic material is set at an opening end of the collar portion of the frame, said frame 24 forming a hole portion 241 which perforates a pipe 13 therethrough, and extending to an upper portion of the side pieces 122a of the upper collar portion of the permanent magnet. At the extending portion, a hole 242 connected with the guide hole 122b of the collar is formed and guides another end of an operating lever 16 outward. Further, a magnetic plate is set on the frame 24, said magnetic plate 25 is attached between the both sides of the frame 21 to form a hole portion 251 connected with the hole portion 241 of the frame, whereby the reduction of the power and the miniaturization can be attained.
