Claims

[Claims for Utility Model Registration] A thrust roller bearing in a structure in which a thrust roller bearing interposed between two relatively rotating members is fixed in an axially immovable manner to an annular race receiving portion provided on one of the members. A protrusion protruding in the radial direction is provided on the inner periphery of the inner race or the outer periphery of the outer race, and the protrusion engages in the axial direction with the race receiving portion of the one member to prevent the race having the protrusion from coming off. A thrust roller bearing characterized in that an annular recess is formed in the race receiving part, and flat parts on both axial ends of the recess are provided in the race receiving part to support the inner peripheral part or the outer peripheral part of the race. fixed structure.
