<P>PROBLEM TO BE SOLVED: To provide a scroll type compressor for preventing flaking in a part in contact with a bush of a radial bearing, while preventing an increase in rolling resistance of a spiral wall of a scroll member to be paired even in high-speed rotation. <P>SOLUTION: In this scroll type compressor, the bush 23 is fitted around an eccentric shaft 17 arranged in an end part of a driving shaft 12, and the bush 23 is relatively rotatably supported by the radial bearing 24 arranged in a boss part 22b formed on a back face of a turning scroll member 22, and the bush 23 is provided with a balance weight 32 integrated with the bush. When the bush 23 tilts, an outer peripheral surface of the bush is brought into contact with the radial bearing 24 only on the end part side provided with the balance weight 32. Specifically, a clearance A between the eccentric shaft 17 and an inner peripheral surface of an eccentric hole 23a of the bush 23 is formed smaller than a clearance C between the radial bearing 24 and the outer peripheral surface of the bush 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
