CONSTITUTION:A boss part 2d is provided on the rear face of a movable scroll part 2, and the crank pin 12a of a crank shaft 12 is fitted in the boss of the boss part 2d. While the movable scroll part 2 and the boss part 2d are connected by a driving pin 17 and an eccentric hole 18 fitted to it, they are also connected by a guide pin 19 and a guide hole 20 fitted loosely to it at a different place from the above. Since the guide pin 19 and the guide hole 20 are loosely fitted with a clearance, if the movable scroll part is driven by the crank pin, the movable scroll part sways by a prescribed amount making the driving pin 17 of the boss part 2d as the center and acts so that the clearance between laps 1a and 2a becomes minimum.

Therefore, the existence of such a radial gap C makes it difficult to seal the radial gap of the compression space 40, and the gas inside the compression space 4 leaks to the low pressure side through the radial gap C. . This ultimately leads to a problem in that the amount of gas discharged from the discharge hole 3 decreases, resulting in a decrease in volumetric efficiency, and the leaked gas has to be compressed again, increasing motor input and lowering the coefficient of performance.
