摘要

A scroll compressor comprising: an orbiting scroll (20) joined with a crank pin (12) provided at an end of a drive shaft (11), the orbiting scroll (20) being supported about the shaft (11) by a bearing member (6) via a drive bush (23), so that the orbiting scroll (20) can be driven in a revolving orbital manner, a balance weight (33) provided on the drive bush (23) by means of shrink fitting, and such that l/d ‰¥ 0.25 and D/d ‰¥ 1.4 are satisfied, assuming that, in a shrink fitted portion (35), an axial-direction length of a fitting portion (35) of the balance weight (33) to be shrink fitted to the drive bush (23) is l, that an inner diameter thereof is d, and that an outer diameter thereof is D.
