Abstract:
1. A scroll type compressor comprising: a main shaft that is rotatably supported in a housing that constitutes an outer shell; a rotating scroll that is rotatably connected to a position offset with respect to a center of the main shaft; a fixed scroll that forms a compression chamber compressing a cooling medium by being opposed to the rotating scroll and is fixed to the housing; a balancer that is provided integrally with the rotating scroll and reduces the imbalance of the rotating scroll; a convex portion which is provided in one of the main shaft or the balancer and protrudes in a direction parallel to an axis line of the main shaft; a concave portion which is provided in the other of the main shaft or the balancer and has an inside diameter larger than an outside diameter of the convex portion and into which the convex portion is inserted; and a first elastic body that is provided in a compressed condition in the direction of the axis line between the main shaft and the balancer and exerts a resistance force on the movement of the convex portion in a direction orthogonal to the axis line in the concave portion.
