Abstract: In a tapered roller bearing, neighboring pillar parts constitute a first engagement allowance in which an inner diameter-side opening width of each of the pockets becomes smaller than a roller diameter at a position of the opening width in a direction of a rotation axis of each of the tapered rollers at at least a part of an inner diameter side of each of the pockets, and constitute a second engagement allowance in which an outer diameter-side opening width of each of the pockets becomes smaller than the roller diameter at a position of the opening width in the direction at at least a part of an outer diameter side of each of the pockets. Bumps are formed on an inner surface of the small diameter ring part in the pockets. Small diameter-side end faces of the tapered rollers facing the bumps are substantially flat surfaces.

Abstract: A tapered roller bearing (1) is includes an outer ring (2) having an outer ring raceway surface (2a) on the inner peripheral surface thereof, an inner ring (3) having an inner ring raceway surface (3a) on the outer peripheral surface thereof, and a plurality of tapered rollers (4) arranged in a rollable manner between the outer ring raceway surface (2a) and the inner ring raceway surface (3a). A large flange (3b) is formed on an end portion of the inner ring (3) on a large-diameter side of the inner ring, and the inner ring raceway surface (3a) continuously extends to the end face (3c) of the inner ring (3) on a small-diameter side of the inner ring. The contact angle (?) is 37°30? to 50°. In this manner, the tapered roller bearing having high moment rigidity and long life can be provided.

Abstract: Provided is a resin cage for a tapered roller bearing in which a mold parting line which is extended in an axial direction is formed in a pillar portion defining a pocket. On facing surfaces of adjacent pillar portions, on an outer diameter side from the mold parting line, a first conical surface which slides in contact with an outer peripheral surface of a tapered roller is formed, and a first flat surface in a radial direction is formed in a portion on the outer diameter side from the first conical surface. On an inner diameter side from the mold parting line, a second conical surface which slides in contact with the outer peripheral surface of the tapered roller is formed, and a second flat surface in a radial direction is formed in a portion on the inner diameter side from the second conical surface.

Abstract: A mounting assembly comprises a rigid bracket having an essentially U-shaped portion and an elastic plate, the tip of which is fixed to the tip of the bracket. A guide rail of a passive seat belt system is inserted into a space between the inner surface of the shaped portion and the elastic plate to be secured to a vehicle body by a bolt.

Abstract: Disclosed herein is a lip suitable for use with a guide rail of a passive seat belt system in which a webbing is displaceable between an occupant-releasing position and an occupant-restraining position while being guided by a member movable along the guide rail. The lip is equipped integrally with at least one elastic clip for fixing the lip on the guide rail. Also disclosed is a combination of lips for such a guide rail. The lips are equipped integrally with at least one elastic clip extending between the lips, whereby the lips are fixed on the guide rail by the clip.

Abstract: Provided is a lip suitable for use with a guide rail of a passive belt system. The guide rail defines an elongated slot through a wall thereof so as to permit displacement of a webbing-carrying movable member along the length of the guide rail. The lip is formed of a lip main body and a gill. When the lip is provided with the guide rail, the lip main body extends along the outer surface of a side wall of the guide rail toward the slot. The gill branches out from a part of the lip main body, which part is located in the vicinity of a free edge of the lip main body. Where the guide rail has a substantially U-shaped transverse cross-section, the lip may preferably be provided on each longitudinal outer side wall of the guide rail.
