The fastener also includes a second ring for engaging the opposite side of the wheel, and a third ring having an inner surface engageable with the tapered outer surface of the boss of the first ring. Bolts connectable to the second and third rings urge the second and third rings axially toward each other whereby the second ring is urged against said opposite side of the wheel so that the wheel is axially pressed between the first and second rings, and the inner cylindrical surface of the boss is radially pressed against the shaft.
