A constant-velocity joint includes an inner member. The inner member has holders that hold respective roller assemblies. Each of the holders has contact regions, which are held in abutment against an inner circumferential wall surface of an inner roller of a corresponding one of the roller assemblies, and non-contact regions, which are spaced from the inner circumferential wall surface of the inner roller. The contact regions are formed by first through fourth lobes, and the non-contact regions are formed by first through fourth recesses, for example. Hypothetical tangential lines L1 and L3, which are tangential to the first lobe and the third lobe, extend parallel to the longitudinal directions of respective guide grooves. Hypothetical tangential lines L2 and L4, which are tangential to the second lobe and the fourth lobe, extend perpendicularly to the longitudinal directions of the guide grooves.
