The small diameter side and the large diameter side of the raceway of the inner ring is an inclined face that is continuous with the raceway. A small diameter flange portion of the retainer is provided with a circumferential inner flange portion that projects to the inner diameter side and a circumferential outer flange portion that projects to the outer diameter side.
