とを特徴とする軸受装置。 In a bearing device in which an outer race is fitted and held movably in the axial direction on the inner periphery of the bearing support part of the bearing housing, and the outer race is biased in the axial direction to apply preload to the rolling bearing. A spring fitting hole is formed on the outer circumferential side of the bearing support part, and a coil spring is disposed in the spring fitting hole.A pressure lever whose middle part is supported as a fulcrum is provided astride the side surface of the bearing housing and the side surface of the outer race. A bearing device characterized in that the tip of the coil spring is brought into pressure contact with one end of a pressure lever, and the other end is configured to press the side surface of the outer race.
