Zusammenfassung:	In a tripod type constant velocity universal joint 1, when D1 represents a large inner diameter being a diameter of a circle connecting radially outer end portions of roller guide surfaces 7 and D2 represents a small inner diameter being a diameter of a circle connecting radially inner end portions of the roller guide surfaces 7, a ratio D2/D1 between the small inner diameter D2 and the large inner diameter D1 is set within a range of from 0.73 to 0.80. Further, when d represents a large diameter of a spline formed in a trunnion hub 8 of a tripod member 3 and PCD represents a pitch circle diameter of the roller guide surfaces 7, a ratio d/PCD between the large diameter d and the pitch circle diameter PCD is set to 0.60 or more.
