Abstract
A compressor having a simplified structure includes a rotation shaft having a spiral groove formed in an outer circumferential surface of the rotation shaft, and a cap member that accommodates a lower portion of the rotation shaft so that the rotation shaft can rotate in the cap member. The cap member may be fixed to one of a stator and a frame such that the cap member does not rotate together with the rotation shaft. Through the simplified structure, oil stored in a sealing case can ascend, and noise caused by rotation of the rotation shaft can be reduced.
