1. A scroll compressor, comprising:
a shaft configured to be rotated by a drive source;
an eccentric bush having a recess portion into which the shaft is inserted, an eccentric portion eccentric to the shaft, and a balance weight for balancing a rotation;
an orbiting scroll configured to be orbited by the eccentric portion; and
a fixed scroll configured to be engaged with the orbiting scroll, wherein a rotational clearance is formed between an outer peripheral surface of the shaft and an inner peripheral surface of the recess portion, and the eccentric bush is formed to be capable of performing a swing motion relative to the shaft in a range of the rotational clearance based on a drive pin configured to connect the shaft and the eccentric bush, and wherein an adjusting mechanism configured to reduce the swing motion of the eccentric bush is disposed between the shaft and the eccentric bush.
