A compressor may include a casing, and an electric drive that is disposed inside of the casing and rotate a rotational shaft. A compression portion may be disposed inside of the casing. The compression portion may include a cylinder, a main bearing, and a sub-bearing, which together define a compression space. The compressor may include at least one first oil drain portion recessed radially inward on one of an outer peripheral surface of the main bearing or the cylinder, which has a relatively smaller diameter. The compressor may further include at least one second oil drain portion formed by penetrating, in an axial direction, a remaining one of the main bearing or the cylinder, which has a relatively larger diameter.
