Abstract
A hermetic compressor is provided that may include a vane that is inserted into a roller, rotates with the roller, and is pushed out toward an inner circumference of a cylinder by rotation of the roller to divide the compression chamber into a plurality of spaces. The vane may include a body having a sealing surface that contacts the inner circumference of the cylinder and inserted into the roller; and a guide that extends from an axial end of the body in a direction crossing a direction the vane slides out, and that is slidably inserted into a guide groove formed on at least one of the first bearing or the second bearing to restrain the vane from sliding out of the roller toward the inner circumference of the cylinder.
