PROBLEM TO BE SOLVED: To provide a scroll type fluid machine capable of smoothly rotating a swing scroll by reducing the force for pushing a crankshaft and an eccentric shaft to a bearing with thermal expansion of the swing scroll. SOLUTION: In the scroll type fluid machine, each crank includes a crankshaft 61 and an eccentric shaft 62 eccentrically arranged relative to a center axis A61 of the crankshaft 61, and a case 5 includes two support side bearings 9 for the crankshaft 61, and a swing scroll 1 includes two scroll side bearings 12 for the eccentric shaft 62. A distance L9 between the center axes of the two support side bearings 9 is set longer than a distance L12 between the center axes of the two scroll side bearings 12. COPYRIGHT: (C)2011,JPO&INPIT |
