Abstract: A scroll compressor is provided in which a boss of an orbiting scroll is inserted into and coupled to a boss coupling recess of a crank shaft, so that friction loss of a bearing portion of the crank shaft may be reduced, compression efficiency and reliability of the compressor may be enhanced, and noise and material costs may be reduced. A bush bearing may be formed as a coating on the boss of the orbiting scroll, so that a thickness of the bearing portion of the crank shaft may be reduced. Since an outer circumferential surface of the bearing portion is in contact with an inner circumferential surface of the boss coupling recess, damage to the bearing portion may be prevented.
