<P>PROBLEM TO BE SOLVED: To suppress change in clearance in a thrust direction between a fixed scroll and a rotary scroll, even when thrust load acts on the rotary scroll. <P>SOLUTION: An outer ring 16A of a rotary bearing 15A is mounted to a bearing mounting cylinder portion 3A of a casing 1 with clearance fit. The bearing mounting cylinder portion 3A hold the outer ring 16A in a state not to be pulled out by a presser plate 19. An inner ring 17A is mounted to an outer periphery of a rotating shaft 13 with interference fit. An outer ring 25A of a rotary bearing 24A is mounted to an inner periphery of the rotating shaft 13 with interference fit, and an inner ring 26A is mounted to an outer periphery of a rotary shaft 21 with interference fit. An outer ring 16B of a rotary bearing 15B is mounted in a bearing mounting cylinder portion 3B with clearance fit, and an inner ring 17B is mounted to an outer periphery of the rotating shaft 13 with interference fit. Further, an outer ring 25B of a rotary bearing 24B is mounted to an inner periphery of the rotating shaft 13 with interference fit, and an inner ring 26B is mounted to an outer periphery of the rotary shaft 21 with clearance fit. <P>COPYRIGHT: (C)2003,JPO |
