Abstract:
A thrust roller bearing cage having pockets for accommodating rollers includes an inner annular portion and cage bars that extend in a radial manner from a radially outer edge of the inner annular portion so as to separate the pockets from each other in a circumferential direction. The inner annular portion has a first axial end surface and a second axial end surface. The first axial end surface has an oil passage groove for guiding lubricating oil to the pockets. The second axial end surface is recessed more than the first axial end surface in an axial direction of the inner annular portion so as to form a recessed portion that communicates with the oil passage groove. The whole of a region of the first axial end surface that is located radially directly inside the cage bars is located radially outside the second axial end surface.
