A scroll compressor includes a stationary scroll 1; an orbiting scroll 2 having a pair of first Oldham keyways 4 on one surface thereof, the orbiting scroll defining a compression chamber 25 in combination with the stationary scroll 1; a frame 20 having a pair of second Oldham keyways 5 and supporting the orbiting scroll 2; and an Oldham ring 6 for inhibiting rotation of the orbiting scroll 2, the Oldham ring having a pair of first Oldham keys 6ab on one surface thereof and a pair of second Oldham keys 6ac on the other surface thereof, the first Oldham keys 6ab slidably engaging with the respective first Oldham keyways 4, the second Oldham keys 6ac slidably engaging with the respective second Oldham keyways 5. The Oldham ring includes at least a pair of projections 7 on the other surface thereof, and the projections 7 have a height such that when the Oldham ring 6 is inclined during simple harmonic motion, one of the projections 7 makes contact with the one surface of the orbiting scroll 2 before each of the first Oldham keys 4 is brought into contact with the corresponding first Oldham keyway 4 at two locations. |
