<P>PROBLEM TO BE SOLVED: To give a sufficient axial force by a small calking load even in a large size bearing, and to inexpensively and certainly fix the bearing 3 to a shaft body 2 in a rolling bearing unit in which the rolling bearing 3 is attached to the outer periphery of the shaft body 2 such as a vehicular hub unit. <P>SOLUTION: This rolling bearing unit is provided with a shaft body 2; an inner ring 42; an outer ring 33; and rolling bodies 34, 35. A cylinder formed at the vehicle inner side end of the shaft body 2 is bent and formed outwardly in a radial direction to form a calked part 5, and the inner ring 42 is fixed to the shaft body 2. A recess 6 is formed at the vehicle outer side end of the shaft body 2, and the recess 6 is formed from the vehicle outer side end to an axial position close to the vehicle inner side more than an end surface at the vehicle outer side of the inner ring 42. <P>COPYRIGHT: (C)2009,JPO&INPIT |
