Scroll compressor having a fitted bushing and weight arrangement

A scroll compressor, comprising:

• a compression mechanism unit including a fixed scroll and an orbiting scroll;
• a crank shaft configured to cause the orbiting scroll to orbit about the fixed scroll;
• a slider provided between the orbiting scroll and the crank shaft and including a tubular portion having an outer circumferential surface and a flange portion projecting from the outer circumferential surface of the tubular portion between a first tubular end and a second tubular end of the tubular portion;
• and
• a balance weight fitted to the slider and including
• a ring-like portion having an inner surface facing an outer circumferential surface of the flange portion,
• a weight portion having an inner surface facing the outer circumferential surface of the tubular portion between the first tubular end and the flange portion, and
• a projection projecting from an inner circumferential surface of the ring-like portion and having an inner surface facing the outer circumferential surface of the tubular portion between the second tubular end and the flange portion, wherein
• the outer surface of the tubular portion between the second tubular end and the flange portion and the inner surface of the projection are fitted together, and
• a gap is provided between the outer surface of the flange portion and a portion of the inner surface of the ring-like portion.
