One end of the elastic member 113 is fitted into the upper elastic member fitting groove 1122, and the other end of the elastic member 113 abuts against the end of the sliding portion 121. Thus, the elastic member 113 can stably transmit the elastic force to the slider 12.
Further, in order to improve the stability of the elastic member 113 in transmitting the elastic force, a lower elastic member insertion groove (not shown) is formed at the end of the sliding member 12, and the other end of the elastic member 113 is fitted into the lower elastic member insertion groove.
Further, in order to improve convenience of implementation and improve charge transfer efficiency, the sliding part 121 includes a sliding part body (not shown) and an insulating sleeve (not shown).
