Claims

[Scope of utility model registration request]

Two cylinders each having a piston with a rack cut therein are arranged in parallel, and the linear reciprocating motion of the piston driven by fluid pressure is converted into a rotational oscillating motion via a pinion meshing with the rack. In the cylinder, two cylinder holes are formed in a non-penetrating manner from one end of a body having a rectangular cross section, and the piston is slidably inserted into each cylinder hole, and the opening end of the cylinder hole of the body is The drive-side pressure chamber and the return-side pressure chamber formed on both sides of each piston are communicated with each other through a through hole cut into the body, and the cover is equipped with a port for supplying and discharging pressure fluid. A piston type swing motor characterized by being provided with.
