PURPOSE: An abrasion preventing device of a scroll compressor is provided to restrict abrasion of a driving shaft or between frames contacting to the driving shaft by supporting radially the driving shaft with rotating a rolling bush together with the driving shaft even if the driving shaft rotates at high speed. CONSTITUTION: An abrasion preventing device of a scroll compressor is composed of a fixed scroll; an orbiting scroll engaged with the fixed scroll to form a plurality of compression chambers, which move continuously, together with the fixed scroll; a frame(10) for rotatively supporting the orbiting scroll in the axial direction and having a shaft hole(11) bored in the central part; a driving shaft(20) inserted into the shaft hole of the frame to support radially and rotatively combined with a rotor of a driving motor to transmit rotary power to the orbiting scroll; and a rolling bush(30) rotatively interposed between sliding surfaces of the frame and the driving shaft to form each bearing surface with inner and outer peripheral surfaces.
