The invention provides a bearing fixing structure. A bolt is prevented from getting loose through a fixing component fixed to a housing through the bolt so that an outer ring is prevented from rotating. The bearing fixing structure comprises a first plane (3) on the outer ring (2), the fixing component (5) with a curved surface (9), and the bolt (7) used for fixing the fixing component (5). The curved surface (9) contacts with the first plane (3) at different positions according to rotating direction and thus prevents the outer ring (2) from rotating. At the time, the direction of the contact load applied to the fixing component (5) becomes the direction passing through the central axis of the bolt (7) or the direction of the torque in the fastening direction of the bolt (7) to the fixing component (5). |
