(54) Vane-type compressor


(57) A vane-type compressor with a reduced coating amount of a solid lubricant used for forming a solid lubricant film on an outer peripheral surface of a rotor is provided. In a vane-type compressor (1) including at least: a cylinder 8a which is housed in a housing (2), and has a complete round inner peripheral surface; a complete round rotor (4) which is housed in the cylinder (8a) such that the center (P1) of the rotor (4) is arranged at a position offset from the center (P2) of the cylinder (8a); and a shaft (3) which is press-fitted into a through hole (4a) formed in the rotor (4), a solid lubricant film (30) is formed on an outer peripheral surface (4b) and a side surface (4c) of the rotor (4), and a thickness (L) of the solid lubricant film (30) is set to a value which falls within a range from 10 µm to 20 µm from an initial stage without applying finish working so that a coating amount of the solid lubricant can be relatively reduced.
