Abstract
Scroll compressor includes a shaft rotatably supported to a casing; an eccentric bush having a recess part into which one end portion of the shaft is inserted, an eccentric part eccentric to the shaft, and a balance weight disposed at the opposite side of the eccentric part with respect to the recess part; an orbiting scroll for performing the orbiting motion in interlock with the eccentric part; and a fixed scroll for forming a compression chamber together with the orbiting scroll. The casing has an orbiting groove in which the eccentric bush performs the orbiting motion, a buffer member is interposed between the orbiting groove and the balance weight. Rotation clearance is formed between the recess part and the shaft. The buffer member is compressed between the balance weight and the orbiting groove before the recess part and the shaft contact each other by the rotation clearance.
