CONSTANT VELOCITY JOINT

PROBLEM TO BE SOLVED: To provide a constant velocity joint which stably suppresses rotational wobbling while employing a simple constitution.SOLUTION: A constant velocity joint has: a cylindrically-formed outer ring 24 in which three pieces of roller guide grooves 26 are formed at an internal peripheral face in an axial direction; a tripod 34 in which a torque transmission angle is formed so as to be changeable with respect to an axial line of the outer ring 24, and which comprises three pieces of tripod shaft parts 38 which extend to the outside of a radial direction; three pieces of rollers 40 which are rotatably supported to the respective tripod shaft parts 38, and rollingly arranged in groove extension directions of the respective roller guide grooves 26; and an elastic torus-shaped member 60 which is arranged between the roller guide grooves 26 and upper parts of external peripheries of the rollers 40. 【課題】簡素な構成を採用しつつ、回転ガタの抑制を安定して行う等速ジョイントとする。【解決手段】等速ジョイントであって、筒形状に形成され、その内周面の軸方向に３本のローラ案内溝２６が形成される外輪２４と、外輪２４の軸線に対しトルク伝達角度が変更可能に配設され、径方向外方に延びる３本のトリポード軸部３８を備えるトリポード３４と、各トリポード軸部３８に回転可能に支持され、各ローラ案内溝２６の溝延伸方向に転動可能に配置される３つのローラ４０と、ローラ案内溝２６とローラ４０の外周上の間に配設される弾性変形可能なトーラス状部材６０を有する。【選択図】図１
