<P>PROBLEM TO BE SOLVED: To enable improvement of durability and suppress occurrence of noise and vibration by making a lubricant reliably and smoothly circulate between a bush and a crankpin in a scroll-type compressor. <P>SOLUTION: In the bush 52 which configures the scroll-type compressor 10, a groove part 80 is formed in a hole part 72 through which the crankpin 70 that eccentrically revolves around a rotation shaft 56 is inserted, to correspond to a rotation shaft axial line (L) side. The lubricant accumulated in this groove part is supplied to the whole sliding part of the bush 52 and the crankpin 70 by a centrifugal force by rotation of the bush 52 around the rotation shaft axial line (L). <P>COPYRIGHT: (C)2013,JPO&INPIT |
