A tripod type constant velocity universal joint, comprising: an outer joint member having track grooves formed at trisected positions on the outer joint member in a circumferential direction of the tripod type constant velocity universal joint to extend in an axial direction of the tripod type constant velocity universal joint; a tripod member comprising trunnion journals radially projecting from trisected positions on a trunnion barrel in the circumferential direction; and spherical rollers each fitted in a rotatable manner about each of the trunnion journals through intermediation of a plurality of needle rollers, of which movement in an axial direction of the trunnion journal is restricted, the spherical rollers being movable in the axial direction of the trunnion journal by relative movement to the needle rollers, and the spherical rollers being received in the track grooves, and each having an outer spherical surface guided by roller guide surfaces formed on both side walls of each of the track grooves, characterized in that a corner portion without having a recess shape is formed at a root portion of the each of the trunnion journals and is connected to a shoulder surface of the trunnion barrel so as to restrict movement of each of the plurality of needle rollers in the axial direction toward the root portion of the each of the trunnion journals by interference between an end surface corner rounded portion of the each of the plurality of needle rollers and the corner portion at the root portion, without contact between the end surface of the each of the plurality of needle rollers and the shoulder surface of the trunnion barrel. an outer joint member having track grooves formed at trisected positions on the outer joint member in a circumferential direction of the tripod type constant velocity universal joint to extend in an axial direction of the tripod type constant velocity universal joint; a tripod member comprising trunnion journals radially projecting from trisected positions on a trunnion barrel in the circumferential direction; and spherical rollers each fitted in a rotatable manner about each of the trunnion journals through intermediation of a plurality of needle rollers, of which movement in an axial direction of the trunnion journal is restricted, the spherical rollers being movable in the axial direction of the trunnion journal by relative movement to the needle rollers, and the spherical rollers being received in the track grooves, and each having an outer spherical surface guided by roller guide surfaces formed on both side walls of each of the track grooves, characterized in that a corner portion without having a recess shape is formed at a root portion of the each of the trunnion journals and is connected to a shoulder surface of the trunnion barrel so as to restrict movement of each of the plurality of needle rollers in the axial direction toward the root portion of the each of the trunnion journals by interference between an end surface corner rounded portion of the each of the plurality of needle rollers and the corner portion at the root portion, without contact between the end surface of the each of the plurality of needle rollers and the shoulder surface of the trunnion barrel.
