Besides, it is provided with a hole part 13a formed to pierce the center of the boss 13 in a shaft direction, a ground pin 14 freely movably inserted in the hole 13a and a leaf spring 15 pressing and energizing the pin 14 to the bottom surfaces of the respective guide rails. Therefore, the pin 14 is pressed and energized by the spring 15, made to put in the hole part at the center of the boss 13 and held.
