The shaft has a small diameter end portion having a diameter smaller than that of the reduced diameter front end open portion and an enlarged diameter portion having an outer diameter larger than an inner diameter of reduced diameter front end open portion. Owing to contact between the enlarged diameter portion of the shaft and the reduced diameter front end open portion of the tube, a progress of the shaft is regulated.
