In a bearing device, a squeeze film damper includes an annular mass member disposed in a floating state between an outer periphery of an outer race and an inner periphery of a bearing retaining member, a first squeeze film damper part formed between the outer periphery of the outer race and an inner periphery of the annular mass member, and a second squeeze film damper part formed between an outer periphery of the annular mass member and the inner periphery of the bearing retaining member. Therefore, due to the floatingly supported annular mass member being eccentric with the opposite phase to a rotating shaft, which is eccentric and undergoes centrifugal whirling, an inertial force acting on the annular mass member counteracts the centrifugal force acting on the rotating shaft, thus enabling a damping effect to be exhibited.
