The invention relates to a scroll compressor, and the scroll compressor comprises a housing; a motor for generating a driving force inside the housing; a rotating shaft rotated by the motor; and a swirling scroll a rotating shaft for rotating; a fixed scroll forming a compression chamber together with the orbiting scroll; and a bearing rotatably supporting the rotating shaft and the orbiting scroll. The orbiting scroll may include a deformation preventing portion for preventing the deformation of the orbiting scroll when connected to the bearing. Thereby, when the bearing is connected to the orbiting scroll, the deformation of the orbiting scroll can be prevented, and the weight, the size, the balance of rotation, the durability, the sound insulation, the vibration, the cost, and the deterioration of the package can be prevented by the above bearing.
