1. A compressor, comprising: a sealing case having a lower portion in which oil is to be stored; a frame disposed in the sealing case; a compression mechanism comprising a cylinder and a piston to compress a refrigerant of the cylinder; an electric motor-operated mechanism comprising a stator fixed to the frame and a rotor that rotates in the stator; a rotation shaft coupled to an inner side of the rotor that rotates together with the rotor, wherein a pickup portion is disposed in a lower portion of the rotation shaft; and a cap member to accommodate the pickup portion and configured to guide the oil to be stored in the lower portion of the sealing case to the rotation shaft, wherein the cap member is disposed at a lower portion of the rotation shaft such that the cap member closely contacts the rotor to prevent a gap from being formed between the rotor and the cap member, and the cap member includes at least one leg portion fixed to at least one of the frame and the stator so that the rotation shaft is rotatable without rotating the cap member.
