The first electrode is supported on the end surface of the main body case, and the second electrode is supported on the movable member set to counterpose the end surface of the above-described main body case. The above-described movable member is displaced to the front and rear direction toward the end surface of the main body case, when the manipulation member is manipulated. The above-described manipulation member is returned to a prescribed position by the first elastic member, when it was opened. Also, the second elastic member for endowing elasticity to the displacing direction when the above-described movable member is approached to the end surface direction of the main body case by the above-described manipulation member, is equipped.
