Abstract
A constant-velocity joint 1 includes an outer ring with three raceway grooves formed therein, a tripod member having three tripod shaft portions, and roller units each having a cylindrical inner roller externally fitted over the corresponding tripod shaft portion and an outer roller. The outer roller has an annular surface facing a ceiling surface of a raceway groove. The ceiling surface includes first and second contact portions and that come into contact with an outer edge of the annular surface when the roller unit is tilted. When an outside diameter of the annular surface is represented as a roller end surface diameter A, a width of the outer roller in an axial direction is represented as a roller width B, and an interval between the first and second contact portions is represented as a contact portion interval H, a relational expression (A+B)/H≧2.5 is satisfied.
