In the mandrel, a cavity part 6d in which a compressed air is introduced and a plurality of holes 2a for ejecting the compressed air outside from the cavity to the outer peripheral surface are formed. In the holes, a valve 7 opening by being pressed with an inner peripheral surface of the sleeve mounted on the mandrel is arranged, and the compressed air ejected from the valve is filled between the outer peripheral surface of the mandrel covered with the sleeve and the inner peripheral surface of the sleeve. |
