PROBLEM TO BE SOLVED: To reduce a manufacturing cost of a compressor which is used for a refrigeration cycle by improving punching processability of a main passage of an oil supply passage formed on a crankshaft, and thereby reducing number of manufacturing steps. SOLUTION: A sliding part (a) between a crankshaft 1 and a sliding bearing 2 which supports the crankshaft 1 is lubricated by lubricating oil supplied through an oil supply passage 7 arranged on the crankshaft 1. A main passage 71 of the oil supply passage 7 is punched as a straight hole only within a range from a lower end face of the crankshaft 1 to its axial intermediate position. An oil blade 9 is arranged on the main passage 71. The oil blade 9 has a through-hole 92 at its upper end, and bent engagement claws 93, 93 at its lower end. The oil blade 9 is engaged with the engagement claws 93, 93 elastically pressed against a peripheral wall of the main passage 71.
