Claims

[Scope of utility model registration request]

Loosely insert a guide rod coaxially into a cylindrical piston rod protruding from one side of the piston,
The guide rod is attached to the head cover so as to be able to swing around its axis but cannot be moved in the axial direction, and the cross section of the part of the guide rod located inside the piston rod is an even-numbered, almost regular polygon, and the surface of the piston on the opposite side of the piston rod is A pair of grooves extending radially opposite each other are formed in the guide rod, and a pawl fixed movably along the groove is accommodated in the groove, and the inner end of the pawl is capable of contacting the outer circumferential surface of the guide rod. A fluid pressure cylinder with a piston rod swinging mechanism, characterized in that the guide rod is further provided with a drive mechanism for swinging the rod about its axis in a fixable manner.
