Claim:
1. A scroll compressor comprising: a housing; a cylindrical rotating shaft rotatably supported by the housing; a fixed scroll fixed to the housing; a movable scroll which opposes the fixed scroll to form a compressing chamber; and a drive mechanism disposed in the housing and configured to allow the movable scroll to make an orbital motion by rotation of the rotating shaft, wherein the drive mechanism includes an eccentric pin extending in parallel with the rotating shaft from an end part of the rotating shaft, and a balancer-integrated bush disposed between the eccentric pin and the movable scroll, including an eccentric hole into which the eccentric pin is inserted, configured to rotate around the eccentric pin, further including a balancer in an integrated manner, and configured to rotatably move relative to the rotating shaft, wherein an elastic member is disposed between a concaved portion of the balancer-integrated bush and the end part of the rotating shaft, and the elastic member regulates a relatively movable range in which the balancer-integrated bush rotatably moves around the rotating shaft relative to the rotating shaft, wherein a face of the balancer-integrated bush that regulates rotation of the balancer-integrated bush relative to the rotating shaft is disposed between the concaved portion of the balancer-integrated bush and the end part of the rotating shaft, and wherein the face of the balancer-integrated bush that regulates rotation of the balancer-integrated bush corresponds to a location where the elastic member is disposed.
