<P>PROBLEM TO BE SOLVED: To improve durability by causing a lubricating oil to surely and smoothly flow between a bush and a crank pin in a scroll compressor, and also suppress occurrence of noise and vibration. <P>SOLUTION: A pin hole 72 into which the crank pin 70 eccentric with respect to an axis coupled with a rotary shaft is inserted is formed on the bush 52 constituting the scroll compressor, and in addition an oil passage 80 orthogonal to the axial line of the bush 52 and passing through the center of the pin hole 72 is formed. The oil passage 80 is structured such that one and the other ends pass through the outer peripheral surface 52a of the bush 52, and, in addition, that angles θ of tangential lines in contact with the outer peripheral surface 52a of the bush 52 with respect to the axial line of the oil passage 80 are formed to be obtuse, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
