PROBLEM TO BE SOLVED: To provide a double roller type tripod-shaped constant velocity joint capable of allowing a worker to assemble a roller unit to a tripod shaft portion without mistaking a direction of the roller unit in the double roller type tripod-shaped constant velocity joint having an approximately spherical tripod shaft portion.SOLUTION: A flange portion 31B projecting to a radial inner side and holding an inner roller 34 and a rolling element, is annularly formed on one end face of an outer roller 31, and an inner component holding portion (35) for holding the inner roller and the rolling element, is disposed at a side of the other end face of the outer roller. An inner peripheral face of the inner roller to which a tripod shaft portion 11A is inserted in a roller unit 30 in which the rolling element and the inner roller are held in the outer roller by the flange portion and the inner component holding portion, is provided with a tripod shaft portion insertion restricting portion (34A) for permitting insertion of the tripod shaft portion only from an end face of a side free from the flange portion of the outer roller in the roller unit. |
