Rolling bearing for assembly of non-driving wheel of car, has fillet allowing radial clearance to fix cap on exterior unit by decreasing external diameter of peripheral side so as to be placed in groove while passing beyond back side

摘要

The bearing has an interior rotary unit (3), a stationary exterior unit (1) and a set of moving bodies (6) that is placed in a bearing space (5) formed between the stationary and rotary units so as to allow relative rotation of the moving bodies. A connection fillet (18) is arranged for allowing elastic radial clearance between a set of side portions (17) and a central portion (16) to fix a cap (13) on the exterior unit by decreasing external diameter of a peripheral side (22) so as to be placed in an annular groove (24) while passing beyond a back side (25).
