Abstract
To realize an increase in lifespan and a reduction in cost in an interlocking mechanism that causes a driving scroll and a driven scroll to rotate synchronously, a through hole is drilled into a peripheral edge portion of a driving scroll side end plate, and a pin member is fixed to the through hole. A base is provided on a driven scroll side spiral projection that faces the through hole. A columnar recessed portion is carved into an opposing surface of the base, and an aluminum rotary body is loosely fitted into the recessed portion. An eccentric hole is drilled into the rotary body, and the pin member is loosely fitted into the eccentric hole. The interlocking mechanism is disposed in an odd number at equal intervals on an outer edge portion of the scroll end plate such that loads exerted on the rotary body act in an identical plane.
