Patent ID: 8480305

Claim:
A resin crown-type cage for an angular contact ball bearing, which rollably holds a plurality of balls, serving as rolling elements of the angular contact ball bearing, between an inner ring and an outer ring at predetermined intervals, comprising: a ring portion; and a plurality of column portions that protrude from the ring portion in an axial direction and that are arranged in a circumference direction, wherein the column portions next to each other in the circumference direction form pockets that house the balls serving as the rolling elements, wherein each of the column portions has a column portion radially inward section that forms a bearing-radial-direction inward side portion of the column portion, and a column portion radially outward section that is connected to the column portion radially inward section at a radially outer end position of the column portion radially inward section, so as to protrude on both sides in the circumferential direction from the column portion radially inward section, wherein an inner surface of each of the pockets is formed in a spherical shape that lies astride the column portion radially inward section and the column portion radially outward section, and wherein a connection position at which the column portion radially outward section is connected to the column portion radially inward section is adjusted to a position radially outward of a pitch circle of the plurality of the balls that are held in the respective pockets so that a thickness of the column portion radially inward section at the connection position is larger than a thickness of the column portion radially inward section at the pitch circle position.
