PROBLEM TO BE SOLVED: To provide a compact tripod type constant velocity universal joint having a simple lightweight structure. SOLUTION: In this tripod type universal joint, in one shaft 1 out of two shafts to which rotating torque is input/output, three cylindrical grooves 5 are provided from the shaft center to the radial direction in circumferentially equally arranged positions within a plane vertical to the axis line of the shaft 1. Spherical rollers 3 are arranged in the respective cylindrical grooves 5 in the one shaft 1 so as to be slidable in the radial direction, respectively. The other shaft 2 out of the two shafts is arranged so as to be slidable in the axis direction with respect to the spherical rollers 3, and projection positions of the spherical rollers 3 to the other shaft 2 hold the circumferentially equally arranged positions.
