PROBLEM TO BE SOLVED: To provide a thrust roller bearing capable of suppressing the abrasion between a holder and rollers and ensuring low torque loss.SOLUTION: A thrust roller bearing comprises: a plurality of rollers arranged radially; and a holder including a plurality of pockets formed radially for holding the respective rollers to be rollable inside, a tin film or a metallic film containing tin at a thickness of 1 to 20 μm is applied at least onto a radially outer end surface of each of the pockets that is contacted by an end surface of each of the rollers by a centrifugal force and to which abrasion tends to occur of the holder, thereby making it possible to solve the problem.SELECTED DRAWING: Figure 1 |
