PROBLEM TO BE SOLVED: To improve durability of thrust bearing by accommodating a thrust load of a rotating shaft appropriately. SOLUTION: A thrust collar 51 is installed on the rotating shaft 15 upon which a turbine 19 and a compressor 20 of a super charger 10 are mounted on both ends thereof, and on the other hand a bearing plate 44 is supported freely movable in axial direction in a support member 41 through which the rotating shaft 15 penetrates, a coned disc spring 50 interposed between the support member 41 and the bearing plate 44 urges the bearing plate 44 to press the thrust collar 51.
