A compact tripod type constant velocity joint with double roller type roller units capable of preventing plastic deformation of snap rings in assembling. In each of the roller units, an outer roller has an inner diameter 'Do' of 26.4 mm or less. The inner diameter 'Do' (mm) of the outer roller, a groove depth 'Depth' (mm) of engaging grooves formed on the outer roller and an outer diameter 'Ds' (mm) of the snap rings satisfy the formula below. Then, in a state where the snap rings are seated in the engaging grooves, diametrical gaps of 0.1 mm or more are formed between outer peripheral ends of the snap rings and groove bottoms of the engaging groove. Do+2xDepth-Ds>=0.1.
