PROBLEM TO BE SOLVED: To provide a bearing device for enabling supply of oil into rolling bearings 20 while restricting the supply amount.SOLUTION: The bearing device includes a cylindrical outer ring housing 10 provided in a casing 2 and having an oil drain hole 15 formed in part of the axial center, and the rolling bearings 20, 20. Oil supplied between an inner peripheral face 5 of the casing 2 and an outer peripheral face 16 of the outer ring housing 10 is supplied through a space between an axial end face 17 of the outer ring housing 10 and a side wall face 6 inside the casing 2 into the rolling bearings 20. The oil passing through the rolling bearings 20 is drained from an annular space 50 through the drain hole 15. In the axial end face 17 of the outer ring housing 10, a cutout groove 14 passing therethrough in the radial direction is formed as an oil flow path. |
