ABSTRACT:
In a supercharger, a pair of oil film dampers are installed by way of oil films on an inner circumferential wall of a bearing housing and respectively install thereon ball bearings for a rotor shaft. A hollow, generally cylindrical thrust member selectively abuts at the opposite axial ends upon the dampers, whereby to hold the oil film dampers, the ball bearings and therefore the rotor shaft in place relative to the bearing housing. The thrust member is fixed to the bearing housing by a pin received in a tangential groove of the thrust member, i.e., a groove elongated in parallel to a tangential line of a circular cross section of the thrust member.
