Abstract: PROBLEM TO BE SOLVED: To perform a smooth acceleration and deceleration in carrying stroke and shorten the time required for returning stroke by forming a bypass passage bypassing a flow control vertical groove, and allowing the flow to the check valve of the bypass passage only in the returning stroke. SOLUTION: When the pressure of a second cylinder chamber is increased in carrying stroke, a piston 6 is moved to the right to gradually increase the clearance between a packing and a sine function groove on the circumference of a cushion ring, and the piston 6 is slowly accelerated. When the piston 6 is advanced, the clearance between a packing 30A and a sine function groove on the circumference of a ring 74A is gradually narrowed, and the piston 6 is gradually decelerated. When the pressure of a first cylinder chamber 71 is increased, the piston 6 is moved to the left, the piston 6 is suddenly accelerated since the inflow quantity to the chamber 71 is not limited, the air within a chamber 72 is discharged through the second check valve 78B of a second bypass passage, and a slide block 7 is collided with an adjuster bolt to stop the piston 6.  Thus, the returning stroke time is shortened.
