自在に支持したことを特徴とする軸受支持構造。One side of the bearing is fitted and supported within the bearing housing, and the other side of the bearing is fitted through an elastic body into the bottom bearing housing with an inner diameter larger than the outer diameter of the outer ring of the bearing, and is pressed and supported in the radial direction. In the bearing support structure, a ring-shaped groove concentric with the center of the inner circumferential surface of the bearing housing is provided on the inner circumferential surface of the bearing housing on the other side, and an opening of an appropriate length is provided in this groove. In addition, a ring spring having a protrusion formed inside by bending a portion inward is inserted, and the protrusion of this ring spring protruding from the inner peripheral surface of the bearing housing presses the other side bearing in the radial direction. A bearing support structure characterized in that the bearing is supported slidably in the axial direction.
