Abstract
A scroll compressor includes a drive shaft and an auxiliary drive shaft which are rotatably supported by stationary scrolls, and an orbiting scroll rotatably supported on these drive shafts through cranks. A resilient member is provided on the crank so as to allow thermal expansion of the orbiting scroll in a direction, along which the drive shafts are lined. With this construction, a distance between bearings for the orbiting scroll and the stationary scrolls is adjusted in accordance with the thermal expansion, and therefore even when the thermal expansion occurs, a smooth motion of the scroll will not be affected.
