PURPOSE:To unit a shifting amount by one rotation and security of strength of a screw by using a leading error between a stopper screw and a screw fixed to a stopper adjusting handle. CONSTITUTION:Oil enters from an oiling port 2 so that a cylinder rod 3 moves forward. At this time, a rear stopper nut 4 abuts to a handle 5 and the stopping position on the forward end is settled. And a stopper is fitted in the adjusting handle 5 as a B portion. Then, the stopper nut 4 is put in link motion by a key, etc., and the stopper nut 4 makes one rotation in the same way. Use of a shifting error between the handle 5 and the stopper nut 4 can freely control an adjusting amount by one rotation.
