ABSTRACT:
A tripod type constant velocity universal joint of a single roller type is provided, which can be used in a vehicle operating at high angles without causing an increase in costs by lowering the level of vibration even at a high operating angle. A tripod type constant velocity universal joint is composed of an outer joint member with three track grooves, extending in its axial direction, on the inner circumferential surface of the outer joint member, a tripod member with three radially projecting leg shafts around the circumference of the tripod member, and rotatable rollers mounted on each leg shaft through a plurality of needle rollers and positioned in the track grooves of the outer joint member, the outer circumferential surfaces of the rollers being guided by roller guide surfaces provided on both sides of the track grooves. In this construction, grooves extending along the track grooves are provided on the roller guide surfaces where the rollers contact.
