Claims

[Scope of utility model registration request]

When rotatably supporting the shaft via a rolling bearing on the inner circumferential wall of the shaft hole, an annular member made of a separate part is fitted and locked on the inner circumferential wall of the shaft hole, and one axial end surface of this member is fitted and locked. The other axial end surface of the outer race of the rolling bearing is abutted and locked, and the one axial end surface of the inner race of the rolling bearing is abutted and locked to the other axial end surface of an annular locking body provided on the outer periphery of the shaft. A locking structure for rolling bearings characterized by:
