A cage includes a pair of annular rings and a plurality of cage bars, and an area enclosed by the pair of annular rings and the circumferentially adjacent cage bars that serves as a pocket that holds the roller. The cage further includes a tab provided so as to protrude from a radially outer area of the cage bars to prevent the roller in the pocket from slipping out through the pocket toward a radially outer side. A surface of a bottom portion of the tab is discontinuous with surfaces of the cage bar, which are located on both sides of the tab in a longitudinal direction.
