Abstract

A fixed constant velocity universal joint (1) characterized in that: the track grooves of an outside joint member comprise first track groove parts (7a) located toward the interior and second track groove parts (7b) located toward the opening; the first track groove parts (7a) are formed having arc shaped ball trajectory central lines (Xa) the center of curvature of which has no offset in the axial direction with respect to the joint center (O) with the plane (M) containing at least the ball trajectory central lines (Xa) and the joint center (O) being inclined with respect to the joint axis line (N N) and the direction of inclination thereof being in the opposite direction at the adjacent first track groove parts (7a) in the circumferential direction; when the ball trajectory central lines (Xb) of the second track groove parts (7b) are projected on the planes (M) the ball trajectory central lines (Xb) have a linear portion and this linear portion is formed inclined such that this linear portion approaches the joint axis line (N N) as this linear portion runs toward the opening side; the end part (A) of the ball trajectory central lines (Xa) of the first track groove parts (7a) is located closer to the opening side from the joint center (O) in the axial direction and the ball trajectory central lines (Xb) of the second track groove parts (7b) are connected to this end part (A); and with a plane (P) containing the joint center (O) as the reference when the operating angle is 0° the ball trajectory central lines (Y) of the track grooves of an inside joint member are formed so as to be mirror symmetric with respect to the ball trajectory central lines (X) of the track grooves of the outside joint member with which a track groove pair is formed.
