PROBLEM TO BE SOLVED: To provide a rotary compressor, having a first member and a second member relatively rotating in an eccentric manner while pressure-contacting each other, capable of improving the operation efficiency. SOLUTION: An eccentric section 27 of a driving shaft 25 fitted in a bearing section 42 of a piston 40 as the first member has an angle section 27a at a portion thereof contacting an inner circumferential surface of the bearing section 42 through lubricating oil. The angle section 27a has a crowning section 27b. An end plate 41 and annular piston section 43 of the piston contacting a cylinder 35 as the second member through lubricating oil have angle sections 41a, 43a, respectively. These angle sections 41a, 43a have crowing sections 41b, 43b, respectively. COPYRIGHT: (C)2009,JPO&INPIT
