Abstract

PURPOSE: To prevent a mechanism for coupling a piston with a screw driver from loosening due to vibration by forming a hole for eliminating relative rotation of a nut at one face side of the piston to thereby clamp the driver to the piston through their threadening.
CONSTITUTION: a nut 13 is engaged within a hole for containing itself provided at the opposite side surface to the driver 1 of a piston 5. The threaded pistor 3 at the base of the driver 1 is filled in the hole 6 of the piston 5 to be engagedat the end 2a thereof with a spanner 17. When the spanner 17 is rotated relatively oppositely to a fastener 15 in the state that the fastener 15 can be set to insert a pin 16 into the gap between the face 14 of the nut 13 and the inner surface of the hole 6, the threads 3 on the driver 1 are engaged with the unt 13 to integrally couple the driver 1 with the piston 5
