A cage (120) includes a radially inward-side annular plate (140), a radially outward-side annular wall (151), a plurality of pillar portions (130), and pockets (131) formed in the pillar portions (130). Rollers (10) are rotatably retained in the pockets (131). An inner peripheral surface (151a) of the radially outward-side annular wall (151) is formed so as to be oblique toward a radially outward direction. A radially outward-side end surface (10a) of each of the rollers (10) has a spherical surface shape. |
