摘要：
The invention reduces a centrifugal force of an orbiting scroll which acts on an auxiliary crank mechanism. A crank pin which is eccentric from a main shaft portion is formed in a drive shaft and attached to an orbiting bearing which is provided in a back face side of an orbiting scroll. The main shaft portion of the drive shaft is rotatably supported by a main bearing. An internal gap of the main bearing is set to a value which is larger than a value obtained by subtracting the double value of an eccentric amount difference between an eccentric amount of an auxiliary crank shaft and an eccentric amount of the drive shaft from an internal gap of the orbiting bearing.
