Document Type and Number:
Japanese Patent JP2007161247
Kind Code:
A
Abstract:

To stabilize fitting attitude of a disc rotor to a hub wheel in a bearing device for an axle.

The bearing device for an axle is mounted in such a state that a disc rotor 5 of a disc brake device is put on the outer end surface of a flange 10 directed outward in the radial direction of the hub wheel 2. The flange 10 is provided with through holes 22 at several circumferential points thereof, and a wheel fitting bolt 12 is fitted into the through hole 11 so as to pass through with engagement of serration provided in the bolt on a head side thereof, and single annular groove 14 is provided in an intermediate part in the axial direction in the inner peripheral surface of an area of the through hole, to which the serration is threaded. With this structure, an influence of a thickness part fluidizing in the periphery of the through hole 11 to the outer end surface of the flange 10 can be prevented, and the outer end surface of the flange 10 is maintained smooth, and the disc rotor 5 can be put on the outer end surface of the flange 10 in the proper attitude.
