Claims

[Scope of utility model registration request]

Three track grooves in the axial direction are formed on the inner surface of the outer ring, and the tripod member assembled inside the outer ring has three leg shafts facing each of the track grooves, allowing rotation around each leg shaft. In a tripod type constant velocity universal joint in which a spherical roller provided in the track groove is incorporated into the track groove, the roller guide surfaces on both sides of the track groove have a spherical outer circumferential surface of the spherical roller having a larger curvature than the spherical outer circumferential surface of the spherical roller. point contact with 3
A tripod type constant velocity universal joint characterized by being formed with two or more surfaces.
