PURPOSE: An anti-rotation device of scroll compressor is provided to reduce material cost by reducing size of an Oldham's coupling and to improve reliability and efficiency of the compressor by reducing abrasion between a key part and a key groove part. CONSTITUTION: An anti-rotation member, Oldham's coupling(120), comprises a body part(121) formed in ring-shape and key parts(122a,122b,122c,122d) protruding on both sides of the body parts and inserted to key groove parts(3b,3c,113a,113b) formed on a frame(110) and a fixed scroll or on the fixed scroll and a rotary scroll(3). One of an inner circumferential surface and a periphery of the body part is formed linearly.
