An oil groove that serves as a lubricating oil flow path is formed, the starting end of this oil groove is communicated with the oil supply path, and the terminal end of the oil groove is located in front of the bearing end of the side plate that pivotally supports the crankshaft. A rotary compressor characterized in that an oil reservoir space is formed between the end of the shaft groove of the shaft portion of the crankshaft and the end of the side plate bearing portion. (2) The rotary compressor according to claim 1, wherein the oil reservoir space is constituted by a groove formed circumferentially on the surface of the shaft portion of the crankshaft. (3) The rotary compressor according to claim 1, wherein the oil reservoir space is constituted by a circumferential groove formed on the inner periphery of the bearing portion of the side plate.
