Abstract
Provided is a resin cage for a tapered roller bearing in which a mold parting line which is extended in an axial direction is formed in a pillar portion defining a pocket. On facing surfaces of adjacent pillar portions, on an outer diameter side from the mold parting line, a first conical surface which slides in contact with an outer peripheral surface of a tapered roller is formed, and a first flat surface in a radial direction is formed in a portion on the outer diameter side from the first conical surface. On an inner diameter side from the mold parting line, a second conical surface which slides in contact with the outer peripheral surface of the tapered roller is formed, and a second flat surface in a radial direction is formed in a portion on the inner diameter side from the second conical surface.
