Abstract: A gas vent plug is mounted in an aperture communicating with a bearing cavity, and includes a metal annular body, and an elastic tubular body constituted of an elastic member in tube form, integral with the metal annular body, and having a vent at one end face of the tube, protruding outwards in the axial direction of the tube. A circular groove is provided at one end face of the elastic tubular body so as to encircle the vent. Accordingly, variation in the working pressure is eliminated even in the case where the interference is increased when the gas vent plug is mounted in the aperture.

Abstract: A bearing assembly includes a full type tapered roller bearing and a roller presser which prevents separation of the rollers not only during transportation but while the outer ring is not mounted. The roller presser includes a ring member, and a plurality of arms extending from one side of the ring member. Each arm is inserted in one of the triangular spaces defined by the tapered raceway of the outer ring and the adjacent tapered rollers. The arms press the rollers against the inner ring. A pair of diametrically opposed bridges are provided, each extending between the free ends of a pair of adjacent arms. The bridges engage two diametrically opposed rollers, thereby preventing separation of the rollers not only during transportation but also while the outer ring is not mounted.
