Abstract
A scroll compressor according to the present disclosure includes a partition wall that divides a sealed vessel into a high-pressure space and a low-pressure space, a non-orbiting scroll provided in the low-pressure space, an orbiting scroll that forms a compression chamber between the orbiting scroll and the non-orbiting scroll, and a rotational shaft. The scroll compressor further includes a main bearing that supports the orbiting scroll, an elastic body that biases one of the non-orbiting scroll and the orbiting scroll so as to separate the non-orbiting scroll and the orbiting scroll from each other, and a plurality of columnar members that are fixed at one ends of the columnar members and are movable at the other ends of the columnar members, and are disposed in a circumferential direction. The non-orbiting scroll or the orbiting scroll that is biased by the elastic body is movable between the partition wall and the main bearing in an axial direction of the rotational shaft. The elastic body is disposed between the plurality of columnar members in the circumferential direction.
