Abstract
An object is to provide a scroll compressor capable of avoiding problems caused by abnormal wear of a retaining ring used to prevent a cylindrical ring from being detached. The scroll compressor includes a crank shaft having a crank pin (C) at a shaft end, a drive bush () into which the crank pin (C) is fitted, a cylindrical ring () that is rotatably fitted to an outer periphery of the drive bush () and whose axial movement is inhibited by a retaining ring () mounted on the tip of the crank pin (C), a drive bearing that is fitted to an outer periphery of the cylindrical ring (). An orbiting scroll fitted to an outer periphery of the drive bearing is driven in an orbiting manner through the rotation of the crank shaft. A rotation inhibitor that interferes with the retaining ring () to inhibit the rotation of the retaining ring () is provided on an end surface of the drive bush ().
