The invention provides a tripod type constant velocity universal joint that can restrain generation of an excessive frictional force inside the joint because of the rotation phase angle of the inner joint member, thereby suppressing vibration and achieving higher rotation durability. The tripod type constant velocity universal joint includes an outer roller rotatably located inside the roller guide section of the outer joint member, and an inner roller spherically fitted to the trunnion of the inner joint member so as to be pivotally rotatable, and to support the outer roller permitting relative rotation and relative axial movement, so that when a torque is applied with the outer joint member and the inner joint member oriented with an operating angle theta, a facet of the outer roller inclined along with the rotation of the inner joint member is sustained by the track groove bottom portion formed in a flat plane.
