PROBLEM TO BE SOLVED: To prevent any insufficient oil supply by supplying oil to the entire sliding part between a cylinder, a piston and blades (24, 34) from an oil supply source such as an oil sump in a rocking piston type compressor having three or more cylinder chambers (C1, C2, C3, C4) from the outer circumferential side to the inner peripheral side.SOLUTION: An oil supply source to introduce lubricant to a compression mechanism is formed. There are formed in the blades (24, 34) blade part sliding surfaces (P1) formed between blade parts (24a, 24b, 34a, 34b) and cylinders (21, 31) or annular pistons (22, 31), and oil supply passages (25, 35) for supplying oil from the oil supply source to bush part sliding surfaces (P2) formed between rocking bush parts (24c, 34c) and the annular pistons (22, 31) or the cylinders (21, 31). |
