Abstract
A tripod type homokinetic universal joint which comprises an outer member, a tripod member, and bearing assemblies interposed between the outer member and the tripod member. Each bearing assembly has a plurality of rows of rollers adapted to roll on rolling guide surfaces on track grooves formed in the inner wall of the outer member. The rolling guide surface is defined by side faces of the track groove and near-corner portions of the base of the track groove. The side faces are so oblique that the track groove will be narrowed toward its inlet. Whereby the rollers cannot get off the rolling guide surface even if no shoulders are formed on the side faces of the track groove.
