Claims

[Claims for Utility Model Registration] An outer joint member having a cylindrical shape with one end open and having a plurality of spherical guide grooves extending in the axial direction on the inner circumference; an inner joint member having a plurality of tripod shafts protruding into each spherical guide groove; a roller member rotatably provided to each of the tripod shafts via a needle bearing and rolling in the spherical guide groove; and a retainer provided at both ends in the axial direction of the needle bearing and a retainer that prevents the roller member from being pulled out, and in which at least the needle bearing is coated with lubricating oil, the roller member is disposed inside the roller member. a pair of ring members fixed to both circumferential ends; a first base joined to one of the ring members; and an elastically deformable first base extending obliquely inward from the first base and having its tip constantly pressed against the retainer. A first seal ring consisting of a bent portion, and a second seal ring joined to the other ring member.
a second seal ring comprising a base and an elastically deformable second bending part that extends diagonally outward from the second base and whose tip is always in pressure contact with the inner joint member, and is applied to the needle bearing. A constant velocity joint characterized by sealed lubricating oil.
