A rotating shaft is rotatably supported inside a bearing, and a plurality of radial protrusions are provided on either the inner circumferential surface of the bearing or the outer circumferential surface of the rotating shaft. In a bearing device in which a rotating shaft is supported by forming an oil film between each of these protrusions and the other party facing the protrusions, the protrusions have a predetermined oil film dynamic pressure. A bearing device characterized in that the bearing device is formed so as to face a counterpart side with an area larger than a certain amount that produces an effect. 2 A rotary shaft is rotatably supported inside the bearing, and a plurality of radial protrusions are provided on either the inner peripheral surface of the bearing or the outer peripheral surface of the rotary shaft, and each of these In a bearing device in which a rotating shaft is supported by forming an oil film between a protruding part and a partner facing the protruding part, the bearing or the rotating shaft provided with the protruding part is formed from a sintered oil-impregnated alloy. and the protrusion is formed so as to face the other side with an area of a certain size or more that produces a predetermined oil film dynamic pressure effect, and at least a portion of the opposing surface of the protrusion is blinded. A bearing device characterized by:
