<p>While using an Oldham mechanism as a spin prevention unit mechanism, an Oldham ring is positively lubricated by keeping a medium mixe with oil on a back surface of a turning scroll, and a compression mechanism is kept compact. In a scroll type compressor in which an Oldham ring (18) is provided between a turning scroll member (11) and a block member (5) that axially supports a drive shaft, a fixed scroll member (10) and the block members (5) hold an annular thrust race (16) that receives a load in an axial direction from the turning scroll member (11) with the thrust race sandwiched therebetween, an end of the turning scroll member (11) is slidably brought into close contact with the thrust race (16) on an entire circumference thereof, the thrust race (16) is brought into close contact with the end surface of the block member (5) to the outer side in a radial direction beyond key groove portions (25b, 25c) which are paired and formed on the block member (5), the turning scroll member (11), the thrust race (16), and the block member (5) define a retention space, and the medium with oil is retained in the retention space.</p> |
