<P>PROBLEM TO BE SOLVED: To restrain generation of noise and vibration, while improving durability by surely and smoothly making lubricating oil flow, in a scroll compressor. <P>SOLUTION: A crank pin 68 is arranged on an end surface of a support arranged in the end part of a rotary shaft on the rotary shaft for constituting the scroll compressor, and the crank pin 68 is inserted into an eccentric hole 70 of a bush 52. A locking groove 74 having first and second flat parts 78 and 80 is formed in the end part of the crank pin 68, and a locking ring 84 having first and second straight line parts 90 and 92 is installed in the locking groove 74. The locking ring 84 faces in its opening part 86 to an oil passage 76 constituted of a cutout part of the crank pin 68 and the eccentric hole 70, and regulates relative rotational displacement to the crank pin 68 under the engaging action of the first and second flat parts 78 and 80 and the first and second straight line parts 90 and 92. <P>COPYRIGHT: (C)2012,JPO&INPIT |
