。[Claims for Utility Model Registration] A turbine shaft is rotatably supported by ball bearings at two locations in the axial direction, and these bearings are supported by a housing via oil film dampers, and the outer rings of both bearings are connected to the oil film damper. is preloaded in the axial direction by a preload spring and a spring bearing arranged on the inner periphery of the oil film damper. In a bearing device in which a small hole for an oil jet toward the bearing is formed, a notch is formed in the end face of the spring bearing that contacts the end face of the outer ring of the bearing, connecting the outer periphery of the spring bearing, the outer ring, and the inner periphery. Features of the turbine shaft bearing device.
