<p>A disc-like spacer 78 arranged below a first roller bearing 54 rotatably supporting a driven crankshaft 52 that forms an anti-rotation system 50 is formed with a plurality of notches 78a in the circumferential direction. A spot face 80 is provided to face the outer circumferential surface of the spacer 78, and communication holes 82 and 86 are drilled on the outer circumferential side of the spot face 80 to extend in the axial direction of the scroll. Also formed is a communication hole communicating the communication hole 86 with the first roller bearing 54 via the notches 78a. A grease nipple 88 is mounted to the communication hole 86. To replenish grease, the fixed scroll 10 is removed from the housing 40 such that the orbiting scroll 20 is exposed, and grease is injected from the grease nipple 88 into the first roller bearing 54 with a grease gun.</p> |
