PURPOSE: A roller assembly for a tripod constant velocity joint is provided to improve lubricating performance by supplying oil to a needle roller and reduce assembly time and manufacturing costs by reducing the number of retainer rings. CONSTITUTION: A roller assembly for a tripod constant velocity joint comprises an inner ring(41), a needle roller(42), an outer ring(44), and retainer rings(43a,43b). The inner ring is installed in the exterior surface of a trunnion of a spider. The needle roller is installed in the exterior surface of the inner ring. The outer ring comprises an oil groove(444) forming in the center of a central part(441) of the inner surface and a retainer groove forming between the central part and an edge part(442) of the inner surface. The outer ring is installed in the exterior surface of the needle roller to reduce frictional force between a housing and a shaft. The retainer ring is installed in the retainer groove of the outer ring.
