PROBLEM TO BE SOLVED: To provide a constant velocity fixed joint appropriate for high velocity at least within a small range of the angle of connection at a low manufacturing cost. SOLUTION: An outside joint part 11 forming an annular member provided with a first longitudinal axis L11 is formed of a first ball raceway track 12, and an inside joint part 13 forming a hub provided with a second longitudinal axis L13 is formed of a second ball raceway track 14, and an annular ball cage 17 is formed of a cage window 16 arranged between the outside joint part and the inside joint part and having torque transmitting balls 15 distributed in the periphery held in a common plane surface. The first and the second ball raceway tracks are extended at a certain distance from each first and second longitudinal axis, and form a cross angle with each longitudinal axis, and distributed in the periphery, and connected to each other so that the cross angle of the pair of ball shafts coincide with each other and opened in the opposite direction in relation to the longitudinal axis. The outside joint part is positioned in both sides of a central joint plane surface and while cut off by the first ball raceway track, and formed of two separate peripheral areas brought in contact with the outside opposite surfaces 19 of the ball cage as the same time as inside guide surfaces 25.
