An oil bath type bearing device which supports a rotating shaft rotating around an axis the bearing device is provided. The oil bath type bearing device includes a plurality of bearing pads which are arranged at intervals in a circumferential direction along an outer peripheral surface of the rotating shaft, an annular carrier ring which supports the plurality of bearing pads from an outer peripheral side and in which an oil supply hole through which a lubricant is supplied is formed, and a casing which covers the carrier ring from the outer peripheral side and holds the lubricant between the rotating shaft and the casing. The oil supply hole penetrate the carrier ring from the outer peripheral side to an inner peripheral side and extends toward a rear side in a rotational direction of the rotating shaft as the oil supply hole goes radially inward with respect to the axis.
