Abstract
In an insertion hole formed in an adapter, a side wall which presses an insertion piece of a stopper with an urging force of a spiral spring has a wall surface parallel to a virtual straight line passing a center of the adapter and positioned on the virtual straight line. Thus, a direction which the wall surface of the side wall presses the insertion piece of the stopper is along a facing direction which the side wall and another side wall face each other, and is not inclined outward in a radial direction of the adapter with respect to the facing direction. Thereby, a pressing force applied from the wall surface of the side wall to the insertion piece of the stopper does not cause the insertion piece to be extruded from the insertion hole. Thus, insertion state of the insertion piece to the insertion hole can be satisfactorily maintained.
