The present invention relates to a scroll compressor. According to the present invention, the scroll compressor can minimize a stirring loss due to stirring oil in a balancing space unit by suppressing inflow of the oil into the balancing space unit or suppressing residual oil as the balancing space unit is formed in a sub frame to accommodate at least one balance weight and an oil discharge hole is formed in a main frame. A thrust surface of the main frame is formed to be adjacent to an axial center of a driving shaft to suppress a leakage in an axial direction in the center of a rotation scroll. The size of the main frame is reduced, and the whole weight of the compressor is reduced. Also, a centering work of the sub frame is facilitated, and the increase in the outer diameter of the sub frame is suppressed so that the the size of the compressor can be reduced. The scroll compressor includes a casing, the main frame, a fixed scroll, the rotation scroll, the driving shaft, the sub frame, an oil pump, the at least one balance weight, and the balancing space unit. |
