    摘要： A bearing (200) includes an outer ring (205) with a first outer roller race (219), a second outer roller race, (219') and a radially inward facing outer ball race (222B). The bearing (200) includes a first and second inner rings (207, 207') that axially abutting one another at an abutment interface. The first inner ring (207) has a first inner roller race (214), the second inner ring (207') has a second inner roller race (214') that are disposed in an interior area coaxially with the outer ring (205). A plurality of first rollers (203) rollingly engage the first outer roller race (219) and the first inner roller race (214). A plurality of second rollers (203') rollingly engage the second outer roller race (219') and the second inner roller race (214'). A plurality of balls (221) rollingly engage the outer ball race (222B) and the inner ball race (222A).

    摘要： A comb-shaped resin retainer (1) includes an annular section (2) and a plurality of pillar sections (3) which protrude to one side in the axial direction from one side of the annular section (2). A gap between the pillar sections (3), (3) adjacent to each other in the circumferential direction serves as a pocket (Pt) for retaining a cylindrical roller (4). A side face (5) of the pillar section (3) which serves as the inner face of the pocket (Pt) is formed in a recessed shape. Each pillar section (3) is tilted so as to become closer to the retainer axial center as the pillar section (3) extends toward the tip of the pillar section (3). A flat portion (5a) is provided on the side face (5) of the pillar section (3) which serves as the inner face of the pocket (Pt). The flat portion (5a) continues axially from the tip portion of the pillar section (3) to the base end portion thereof.
