A case is a cylinder-shaped member and accommodates a connector body in a front end portion thereof. The connector body can slide back and forth with respect to the case. The case is provided with a slider in the inside thereof. One of the end portions of the slider projects forward from the case. The slider can slide in an axial direction. A stopper member is provided near a front end of a connector bar, at the back of the slider. The stopper member touches the slider and can move in response to movement of the slider. The stopper member locks the case and the holding member. That is, the stopper member functions as a case-locking mechanism for preventing the case from moving with respect to a holding member. |
