ROLLING BEARING UNIT FOR SUPPORTING WHEEL

摘要

PROBLEM TO BE SOLVED: To provide a structure capable of increasing the supporting rigidity to the input applied to an outer wheel side supporting flange 6 via an outer wheel side fitting surface 15 from a caliper or a support during the braking without increasing the wall thickness of an outer wheel 1. SOLUTION: To solve the above-described problem, the thickness in the axial direction of the outer wheel side supporting flange 6 for supporting and fixing the caliper or the support is increased to the inner side in the radial direction.
