Abstract: A scroll compressor is disclosed. The scroll compressor may include an anti-rotation mechanism provided with an anti-rotation pin and an anti-rotation ring between an orbiting scroll and a scroll support member facing the orbiting scroll, and an axial thickness of the ring body portion constituting the anti-rotation ring may be larger than an axial depth of a ring insertion groove in which the anti-rotation ring is inserted. This can allow the orbiting scroll and a member facing the same to be spaced physically apart without a separate member, to secure a gap for oil to flow, such that the oil can be smoothly supplied between the orbiting scroll and the member, thereby suppressing seizure or/and friction loss between the orbiting scroll and the member.
