<p>PROBLEM TO BE SOLVED: To provide a scroll compressor capable of improving the shrinking strength of a balance weight set larger in proportion to an increase in the rotational speed of a compressor with respect to a drive bush, and securing a space for accommodating and installing the balance weight.SOLUTION: Provided is a scroll compressor configured so that an orbiting scroll is coupled to a crankpin provided on one end of a drive shaft pivotally supported by a bearing member via a drive bush 23 so the orbiting scroll can be driven to make an orbital motion, a balance weight 33 being integrally shrunk-fitted to the drive bush 23, and an axial length i of a fitted portion 35 shrunk-fitted into the balance weight 33-side drive bush 23 in a shrunk-fitted portion, an inside diameter d of the fitted portion 35, and an outside diameter D of the fitted portion 35 satisfying l/d≥0.25 and D/d≥1.4.</p> |
