Claims

[Claims for Utility Model Registration] In a bearing structure comprising a rotating shaft and a bearing that holds the rotating shaft in a cantilevered manner, oil is applied to a position of the rotating shaft corresponding to the bearing due to rotation of the rotating shaft. A spiral groove is formed so as to flow in the direction, and the relative position of the rotating shaft in the axial direction with respect to the bearing is controlled so that the portion of the rotating shaft in which the groove is formed is pivotally supported within the bearing. characterized by the provision of means for regulating,
