置。 A working chamber 9 is provided on one side of the piston 8 and a spring chamber 10 is provided on the other side in the cylinder body 7 of the single-acting spring return type fluid pressure operated cylinder, and the piston rod 14 is inserted into the end wall of the working chamber 9 from one side of the piston 8. 9a, a compression coil spring 15 for piston return is provided in the spring chamber 10, an output screw hole 17 is bored from the outer end surface 14a of the piston rod 14 toward the piston 8 side, and a clamp is inserted into this output screw hole 17. The shaft 19 is screw-fitted so that it can be adjusted forward and backward, and the clamp tool 20 is interlocked and connected to the tip of the clamp shaft 19.
A rotation restraint shaft 26 is eccentrically protruded from the other side of the piston 8, and a rotation restraint hole 27 is eccentrically formed in the end wall 10a of the spring chamber 10, and the rotation restraint hole 27 is inserted into the rotation restraint hole 27 at this eccentric position. In a piston rotation restraint device of a single acting spring return type cylinder type fluid pressure clamp configured to restrain the rotation of the piston 8 by slidably fitting the restraint shaft 26, the rotation restraint shaft 26 and the rotation are restrained. A spring interposition space 28 is provided between the fitting surfaces with the restraint hole 27, a compression coil spring 15 for piston return is arranged in the spring interposition space 28, and the rotation restraint shaft 26 is inserted into the rotation restraint hole 27 so that the piston is inserted into the rotation restraint hole 27. A piston rotation restraint device for a single acting spring return type cylinder type fluid pressure clamp, characterized in that the piston rotation restraint device is slidably fitted via a return compression coil spring 15.
