PROBLEM TO BE SOLVED: To reduce a manufacturing cost compared to conventional examples and to adopt a structure facilitating assembly thereof, in the structure for positioning a bearing for rotatably supporting an intermediate region in an axial direction of a turbine shaft of a supercharger to a side hole of a housing. SOLUTION: Grooves 51a and 51b extending in a circumferential direction are installed on one end side in the axial direction on a periphery of the bearing 5. Inner linear portions 22a and 23a of at least one pair of arm parts 22 and 23 on a retainer plate 20 are fitted into the grooves 51a and 51b, the retainer plate being fixed on one opening side of the side hole in the housing and having a substantially U-shaped notch 21 situated nearly in the center.
