To provide a structure in which phase matching between a screw hole provided in a rotary flange of a hub and a bolt insertion hole provided in a braking rotor can be readily performed.SOLUTION: In a hub unit bearing with a braking rotor, a projection part 41 projecting toward an inside in a radial direction is provided at an inner peripheral surface of a brake rotor 3 and a slit 17 opened at an outer end surface in an axial direction and at an outer peripheral surface and extending in the axial direction is provided in a brake pilot part 16. When the brake rotor 3 is externally fitted to the brake pilot part 16, the projection part 41 is engaged with the slit 17 without any backlash in a circumferential direction.SELECTED DRAWING: Figure 1
【課題】ハブの回転フランジに設けられたねじ孔と制動用回転体に設けられたボルト挿通孔との位相合わせを容易に行える構造を提供する。【解決手段】ブレーキロータ3の内周面に、径方向内方に向けて突出した突起部41を設けるとともに、ブレーキパイロット部16に、軸方向外端面及び外周面に開口し、かつ、軸方向に伸長したスリット17を設ける。ブレーキロータ3をブレーキパイロット部16に外嵌する際に、突起部41をスリット17に対し、円周方向に関するがたつきなく係合させる。【選択図】図1
