Abstract:
At a state where central axes of the drive shaft and the driven shaft are matched, the drive-side concave-convex portion is engaged with a half portion on the other axial side of the coupling-side concave-convex portion with a drive-side gap of which a circumferential width size increases towards the other axial side being interposed between a circumferential side surface of each drive-side convex portion and a circumferential side surface of each coupling-side convex portion. At the state where the central axes of the drive shaft and the driven shaft are matched, the driven-side concave-convex portion is engaged with a half portion on one axial side of the coupling-side concave-convex portion with a driven-side gap of which a circumferential width size increases towards one axial side being interposed between a circumferential side surface of each driven-side convex portion and a circumferential side surface of each coupling-side convex portion.
