Abstract
A centering process and fastening bolt are not required for assembling a fixed scroll and an orbiting scroll of a scroll compressor that includes a hermetically sealed container and a compression mechanism. The fixed scroll includes a cylindrical portion formed in a circumferential direction on an outer circumferential side of the fixed wrap, a flange provided in the circumferential direction further outside of the cylindrical portion, and a first hole provided in the flange in an axial direction. The frame includes an inner circumferential surface, a flange provided in the circumferential direction further outside of the inner circumferential surface, and a second hole in the axial direction which is provided in a position of the flange opposite to the first hole. A knock pin is inserted in the first and second holes to prevent the frame and the fixed scroll from being displaced in the rotational direction.
