The present invention relates to a compressor in which a rotary member is suspended on a stationary member and rotated to compress the refrigerant. In the stationary member, top and bottom ends of a stationary shaft are fixed to improve the structural stability and assembly property. Bearing covers are provided on a contact portion of the stationary member and the rotary member such that the rotary member can be rotated when suspended on the stationary member. This stabilizes the operation. In the rotary member, a vane is integrally formed with a roller and mounted on a vane mounting hole of a cylinder-type rotor. This reduces the vibration and prevents refrigerant leakage to improve the compression effect. Although the rotary member is provided on an outer circumferential surface of the stationary member, it is possible to perform the suction and discharge of the refrigerant in the axial direction. This can lower the product height. The oil stored in a hermetic container is supplied to a lubrication passage provided between the stationary member and the rotary member, thereby reducing a friction loss between the components and achieving the operation reliability.
