Abstract:
A hub unit bearing includes: a hub spindle; an inner ring; an outer ring member; a plurality of tapered rollers that are rollably provided between outer circumferential surfaces of the hub spindle and the inner ring and an inner circumferential surface of the outer ring member; a cage including a large-diameter-side annular part, a small-diameter-side annular part; and a sealing device including a metal insert, wherein: the metal insert includes a cylindrical part that is mounted on the inner circumferential surface of the outer ring member and a flange part that radially extends inward from one end of the cylindrical part; and an engaging projection is provided on an outboard side end face of the large-diameter-side annular part of the cage, and an engaging groove engaged with the engaging projection is provided on an inboard side end face of the flange part of the metal insert.

Claim (Index 1):
A hub unit bearing comprising:\n a hub spindle; an inner ring that is fitted onto and fixed to the hub spindle; an outer ring member that is disposed around the hub spindle and the inner ring; a plurality of tapered rollers that are rollably provided between outer circumferential surfaces of the hub spindle and the inner ring and an inner circumferential surface of the outer ring member; a cage that retains the plurality of tapered rollers at an outboard side end at approximately regular intervals in a circumferential direction; and a sealing device that blocks an opening of an end of a bearing internal space at the outboard side end, wherein: the cage includes a large-diameter-side annular part, a small-diameter-side annular part that is disposed concentrically with the large-diameter-side annular part, a plurality of pillar parts that connect the large-diameter-side annular part and the small-diameter-side annular part in an axial direction and are provided at approximately regular intervals in a circumferential direction, and pockets that are formed between the pillar parts adjacent to each other in the circumferential direction and rollably retain the tapered rollers; the sealing device includes an annular metal insert that is fixed to an inner circumferential surface of the outer ring member and a seal member provided on an outboard side end face of the metal insert; the metal insert includes a cylindrical part that is mounted on the inner circumferential surface of the outer ring member and a flange part that radially extends inward from one end of the cylindrical part; and an engaging projection is provided on an outboard side end face of the large-diameter-side annular part of the cage, and an engaging groove engaged with the engaging projection is provided on an inboard side end face of the flange part of the metal insert.
