The first stopper 141 is formed such that the guide surface 141a is inclined so that the first stopper 141 does not interfere with the forward movement for the arrangement structure of FIG. 3 to 5 of the sliding cover 30, and the reverse locking surface ( 141b) is engaged with the engaging portion 36 of the sliding cover 30 disposed in the second position, thereby making it impossible to reverse movement for the arrangement structure shown in FIG. 5 to FIG. It is impossible to reuse the outer cylinder 10.
