    摘要: A cross groove-type constant-velocity universal joint includes an inner ring (10) having an outer circumferential surface on which ball grooves (12a, 12b) tilted in mutually opposite directions with respect to an axial line are alternately formed in a circumferential direction; an outer ring (20) having an inner circumferential surface on which ball grooves (22a, 22b) tilted in mutually opposite directions with respect to the axial line are alternately formed in the circumferential direction; a ball (30) received in an intersection of a pair of the ball groove (12a, 12b) of the inner ring (10) and the ball groove (22a, 22b) of the outer ring (20); and a cage (40) interposed between the inner ring (10) and the outer ring (20) to retain the ball (30) on the same plane. The maximum diameter of the outer circumferential surface of the inner ring (10) is greater than the minimum diameter the inner circumferential surface of the cage (40). On both end portions in the direction of width of the outer circumferential surface of the inner ring (10), spherical portions (16a, 16b) which have the centers of curvature at the positions offset by a predetermined distance across the center of width of the inner ring (10) are provided. Furthermore, the inner circumferential surface of the cage (40) is provided with a cylindrical portion (44) at a central portion in the direction of width, and spherical portions (46a, 46b) provided at both end portions, the spherical portions having the centers of curvature at the positions offset outwardly by a predetermined distance from the center of width of the cage (40).
