摘要： A thrust roller bearing includes a plurality of rollers, a cage, and a race. Each of a first member and a second member of the cage includes an annular web, an inner flange, and an outer flange. The inner flange of the first member and the inner flange of the second member are fixed to each other by crimping. A tab protruding in an axial direction is formed on the outer flange of the second member, and is inserted into one of a plurality of pockets of the first member. The race includes an annular portion forming a raceway surface, an outer race flange forming a first guide surface that guides the cage, and a guide portion forming a second guide surface that guides a shaft member.

摘要： A thrust roller bearing includes: a plurality of rollers which are radially arranged; a retainer having a pocket which is formed in a circular ring shape as a whole and rollingly retains the plurality of rollers; and at least one raceway ring which is provided with a race surface on which the plurality of rollers roll. The raceway ring includes an iron raceway ring and a resin raceway ring having insulating properties, and the iron raceway ring and the resin raceway ring are integrally assembled by being engaged with each other. In addition, the raceway ring may include a resin raceway ring having insulating properties and a pair of iron raceway rings disposed on both front and back surfaces of the resin raceway ring, and the pair of iron raceway rings and the resin raceway ring may be integrally assembled by being engaged with each other.

摘要： A thrust bearing includes: a retainer that is provided with a plurality of pockets; a plurality of rollers that are arranged so as to freely rotate inside the plurality of pockets; and at least one first race that has an annular-shaped first race section in which the plurality of rollers move. The first race is provided with a hook curl section that is formed by bending the first race section from an outer-diameter-side periphery thereof toward the inner-diameter side obliquely in the radial direction, and an outer peripheral surface of the retainer has a conical surface that is formed so as to be substantially parallel to an inner peripheral surface of the hook curl section. The inner peripheral surface of the hook curl section holds the retainer without separating therefrom by contacting the outer peripheral surface of the retainer in a sliding manner.
