An inner ringis fit to a stepped partformed on the inner end of a hubA desired pre-load is applied to rolling elementsin a state that an outer end faceof the inner ringis butted against a step surfaceformed on the hubThe inner ringis fit to the hubby interference fitting causing a static friction force, which is larger than a thrust load acting on the inner ringbased on the pre-loading. Therefore, the inner end face of the inner ringis clamped with a caulking portion, which is formed by expanding outward in the diameter directions a cylindrical portionformed in the inner end of the hub
