PROBLEM TO BE SOLVED: To provide a new type sliding type constant velocity ball joint increasing a mounting angle and comparatively shortening a moving distance. SOLUTION: A first external raceway forms a first raceway pairing in which first control angles are opened in a first shaft direction and first balls are held, together with a first internal raceway. A second external raceway forms a second raceway pairing in which second control angles are opened in a second shaft direction and second balls are held, together with a second internal raceway. In this case, the control angles are defined as angles formed by tangential lines of ball contacts within the raceways. An external joint part and an internal joint part can be relatively moved in a shaft direction. When the joint parts are relatively moved in the shaft direction, a first control angleβ1 and a second control angleβ2 change in opposite directions each other. The moving distance in the shaft direction is limited to an observation of a minimum value of at least 8 deg. for each further smaller control angle.
