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 the balancer-integrated bush and at least one of the rotating shaft and the eccentric pin, 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 the balancer-integrated bush comprises a body and a projecting portion which projects in parallel with the rotating shaft from the body towards the rotating shaft, the projecting portion includes a first opposing surface opposing a peripheral surface of the rotating shaft, the body includes a second opposing surface opposing an end surface of the rotating shaft, and the first opposing surface and the second opposing surface form a concaved portion capable of accommodating the end part of the rotating shaft, characterised in that the elastic member is attached to a part opposing the first opposing surface within the peripheral surface of the rotating shaft, or to the first opposing surface. 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 the balancer-integrated bush and at least one of the rotating shaft and the eccentric pin, 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 the balancer-integrated bush comprises a body and a projecting portion which projects in parallel with the rotating shaft from the body towards the rotating shaft, the projecting portion includes a first opposing surface opposing a peripheral surface of the rotating shaft, the body includes a second opposing surface opposing an end surface of the rotating shaft, and the first opposing surface and the second opposing surface form a concaved portion capable of accommodating the end part of the rotating shaft, characterised in that the elastic member is attached to a part opposing the first opposing surface within the peripheral surface of the rotating shaft, or to the first opposing surface.
