Abstract
Circumferential rigidity of both axial end portions of each coupling-side convex portion is lower than circumferential rigidity of an axially intermediate portion of each coupling-side convex portion. The drive-side concave-convex portion is engaged with a half portion on the other axial side of the coupling-side concave-convex portion. The driven-side concave-convex portion is engaged with a half portion on one axial side of the coupling-side concave-convex portion.
