PROBLEM TO BE SOLVED: To provide a bearing fixing structure capable of inhibiting rotation of an outer race without generating loosening at a bolt by using a fixed member fixed to a case with one bolt.SOLUTION: A bearing fixing structure has a first flat face 3 which is formed at an outer race 2 and oriented toward the outside of the radial direction while being parallel with the axial line of a bearing 1, a fixed member 5 having a curved face 9, and a bolt 7 for fixing the fixed member 5 to the case 6. When the outer race 2 starts to rotate, the curved face 9 inhibits the rotation by contact with the first flat face 3 in a portion which differs according to its rotation direction. The direction of a contact load imparted to the fixed member 5 at that time becomes a direction which passes through a center axial line of the bolt 7 or a direction in which torque in the fastening direction of the bolt 7 is imparted to the fixed member 5. |
