<p>A plurality of notches (78a) are circumferentially formed on a disc-shaped spacer (78) positioned below a first rolling bearing (54) that rotatably supports a driven crankshaft (52) that constitutes a rotation preventing mechanism (50). A spot facing part (80) is disposed so as to face the outer peripheral surface of the spacer (78), communication holes (82 and 86) are drilled on the outer periphery side of the spot facing part (80) in a scroll axis direction, and a communication hole, which is linked to the first rolling bearing (54) via the notches (78a), is formed from the communication hole (86). A grease nipple (88) is attached to the communication hole (86), a fixed scroll (10) is detached from a housing (40) when replenishing grease, exposing an orbiting scroll (20), and grease is injected with a grease gun from the grease nipple (88) into the first rolling bearing (54).</p> |
