Claims

[Scope of Claim for Utility Model Registration] In a three-lobed roots rotor in which the convex portions and concave portions are formed into a convex arc face and a concave circular face, and the convex portions and concave portions of each rotor rotate in continuous close contact, the center connecting the rotor axis. A three-lobed roots rotor characterized in that a groove in the axial direction that escapes contact with the convex portion is formed by recessing a concave portion in contact with the convex portion on line X- _X1 .
