Abstract
A tripod type constant velocity universal joint comprises a tripod member (4) having three radially protruding trunnions (5), each of which rotatably carries a roller (7) with cylindrical rolling elements (6) therebetween. The outer circumferential surface of the trunnion (5) assumes a true spherical surface (m) having its center on the axis of the trunnion (5) or is defined with a combination of true spherical surfaces (m.sub.1) lying at both axial end portions of the trunnion (5) and having its center on the axis of the trunnion and an intermediate curved surface (m.sub.2, m.sub.3) standing between the true spherical surfaces (m.sub.1) and having a radius of curvature larger than those of the true spherical surfaces.
