<p>The scroll compressor (1) includes a fluid-induced distortion reducing weight (81, 82, 83) which reduces distortion of a crankshaft (40) in a direction of a fluid load. The fluid-induced distortion reducing weight (81, 82, 83) includes an upper fluid-induced distortion reducing weight (81) whose center of gravity locates away from an axial center of the main shaft (41) in a direction opposite to the fluid load direction, a middle fluid-induced distortion reducing weight (82) whose center of gravity locates away from the axial center of the main shaft (41) in a same direction as the fluid load direction, and a lower fluid-induced distortion reducing weight (83) whose center of gravity locates away from the axial center of the main shaft (41) in a direction opposite to the fluid load direction. The upper, middle, and lower fluid-induced distortion reducing weights (81, 82, 83) are balanced with one another.</p> |
