PURPOSE:To reduce direct function of thrust force onto a pin by constructing an anti-rotation mechanism with two thrust plates face contacting each other and coupling pins therefor. CONSTITUTION:A fixed side thrust plate 53 and a movable side thrust plate 55 are arranged slidably each other and pins 51 are provided to both plates 53, 55. The large diameter section 51a of each pin 51 is fitted rotatably in a hole section 53a made in the fixed side thrust plate 53 while the small diameter section 51b of each pin 51 is inserted rotatably into the hole section 55a of the movable side thrust plate 55 through a metal bearing 56. Consequently, when a crank shaft 13A rotates, rotation of the movable side scroll member 41 is suppressed through the plurality of pins 51 arranged in the circumferential direction. |
