Abstract
In a constant velocity joint on the double Cardan type including a pair of flange yokes each having an annular flange portion and a pair of arm portions and connected together at the flange portions to define a radially inwardly open annular groove therebetween; a pair of pin yoke each having a connection end portion, a spherical end portion and a pair of arm portions connecting the connection end portion and the spherical end portion; a pair of cross pieces each pivotably connecting the pair of arm portions of each one of the flange yokes and the pair of arm portions of each one of the pin yokes in a manner of universal joint; and a centering disk bearing a socket portion for receiving the spherical end portions of the pair of pin yokes and slidably received in said annular groove at an outer peripheral portion thereof, the improvement is in that the socket portion of the centering disk is eccentrically shifted from a diametrical center of the centering disk, so that the centering disk is held from random rotation relative to the flange yokes.
