<P>PROBLEM TO BE SOLVED: To solve a problem with a conventional multistage type compressor wherein, when a foreign material is caught by oil blades for raising oil, the oil blade is deformed or fallen and, especially in an upper compressing mechanism portion, abnormal wear and seizure due to a lack of oil supply occur. Ž<P>SOLUTION: An oil supply hole of a multistage type compressor on a rotary shaft lower end side is provided to be inclined so as to prevent deformation and a fall of an oil supply mechanism due to a foreign material. Oil can be thereby stably supplied to a sliding portion of a compressing mechanism portion positioned upside. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
