PROBLEM TO BE SOLVED: To provide a slide tripod-type constant velocity joint which is small in the number of part items, easy in manufacturing, and has a retainer for preventing the come-off of rolling bodies.SOLUTION: A slide tripod-type constant velocity joint comprises an outer ring 10, a tripod 20, a roller 30, a plurality of axial rolling bodies 40 and a retainer 50. Holes 24 of prescribed depths having openings at tip face are formed at tripod shafts 22, and the retainer 50 comprises: a cylinder part 52 having an external peripheral face which is fit to an internal peripheral face of the hole having the prescribed depth of each tripod shaft; an annular contact part 58 which is connected to the cylinder part 52, arranged outside a radial direction of each tripod shaft, abuts on an end of each axial rolling body 40 at an abutment point B, and regulates the movement of the axial rolling body to a come-off direction. 【課題】部品点数が少なく、製作が容易である、転動体の抜けを防止するリテーナを備えた摺動式トリポード型等速ジョイントを提供する。【解決手段】外輪１０と、トリポード２０と、ローラ３０と、複数の軸状転動体４０と、リテーナ５０と、を備え、各トリポード軸２２には、各先端面に開口を有する所定深さの穴２４が形成され、リテーナ５０は、各トリポード軸の所定深さの穴の内周面に嵌合される外周面を備えた筒部５２と、筒部５２と連結されて各トリポード軸の径方向外方に配置され各軸状転動体４０の端部と当接点Ｂで当接して各軸状転動体の抜け方向への移動を規制する環状の接触部５８と、を備える。【選択図】図１
