Zusammenfassung:	PROBLEM TO BE SOLVED: To enhance energy efficiency of an air compressor by reducing internal leakage at an outer peripheral clearance by sufficiently applying sealing effect by oil even to an outer periphery of a male rotor in an oil-cooling type screw air compressor. SOLUTION: A section becoming an outer peripheral arc is provided on a part of a tooth profile of the male rotor. Leakage length to some extent is ensured in the outer peripheral clearance during operation and the sealing effect by viscosity and surface tension of the oil is increased.
