Vehicular wheel bearing having improved sealing property

A vehicular wheel bearing (100) for rotatably mounting and supporting a vehicular wheel to a vehicle body, the vehicular wheel bearing comprising:

• a wheel hub (210) to which the vehicular wheel is mounted and which rotates with the vehicular wheel;
• at least one inner ring (220) mounted to the wheel hub (210);
• an outer ring (300) mounted and fixed to a vehicle-body-side member;
• a plurality of rolling elements (400) of rotatably supporting the wheel hub (210) and the inner ring (220) relative to the outer ring (300);
• an inboard-side sealing member (500) which performs sealing at an axial inner end portion of a bearing space portion in which the rolling elements (400) are located;
• and
• an outboard-side sealing member (600) which performs sealing at an axial outer end portion of the bearing space portion in the rolling elements (400) are located,
• wherein the outboard-side sealing member (600) comprises a frame (700) press-fitted to the outer ring (300) and an elastic sealing part (800) integrally attached to the frame (700),
• the frame (700) comprises a press-fitting part (710) and a flange part (720) bent and extending from the press-fitting part (710),
• the elastic sealing part (800) comprises a base part (810) with which all or a part of the frame (700) is covered, one or more of sealing lips (820) formed to extend from the base part (810), an overmold part (830) which extends beyond an inner axial end portion (714) of the press-fitting part (710) of the frame (700) and is mounted in close contact with an outer circumferential surface of the outer ring (300), and
• the overmold part (830) is configured to be axially spaced apart from a press-fitting surface (712) of the press-fitting part (710) of the frame (700),
• wherein the press-fitting part (710) of the frame (700) comprises a corner portion (716) of a rounded or chamfered shape in an inner circumferential portion of the inner axial end portion (714), and
• the overmold part (830) is formed so that the corner portion (716) is partially covered therewith, and
• wherein an intersection point P of the corner portion (716) and the overmold part (830) is configured to be located at a distance of 0.01 mm or more in a radial direction from an installation surface (310) to which the frame (700) of the sealing member (600) is press-fitted.
