PROBLEM TO BE SOLVED: To prevent increase of a bearing torque caused by that engine oil resides in an annular gap to increase an agitation resistance of the engine oil in a rolling bearing.SOLUTION: A bearing device for a turbocharger includes, in an inner peripheral side of an outer ring housing 10, a cylindrical outer ring spacer 13 both end faces 35 in the axial direction of which come into contact with end faces 27 of outer rings 22 to maintain a gap between rolling bearings 20. An inner diameter 13R of the outer ring spacer 13 is larger than an inner diameter 22R of the outer ring 22, and a center shaft 13A of the outer ring spacer 13 is eccentric downward with respect to a center shaft 22A of the outer ring 22. |
