Claims

[Scope of utility model registration request]

A driven rotor is rotated in a casing with a phase shift relative to the driving rotor through a driving rotor rotated by a rotor and a gear that meshes with a gear attached to one end of the rotor shaft to pump gas. In the Roots compressor, a heat pipe is inserted along the respective axes of the driving rotor and the rotor, and a heat pipe is installed along the axis of the driven rotor, and a fin is attached to the other end of each of these heat pipes. A Roots type compressor further characterized in that fins are formed on the inner and outer surfaces of the cover that covers both of the fins.
