An apparatus for fastening a wheel, having a boss hole therein, to a shaft. The fastening apparatus includes an axially slit outer ring having a cylindrical outer peripheral surface fitted into the boss hole, a tapered inner peripheral surface, a support flange formed at one end of the ring adjacent the small diameter end of the tapered surface for direct engagement with the shaft, a cylindrical inner peripheral surface formed at the large diameter end of the tapered surface, and an enlarged annular end flange formed at the other end of the ring. The fastening apparatus also includes an inner ring having a cylindrical inner peripheral surface for direct engagement with the shaft, a tapered outer peripheral surface complementary to the tapered inner peripheral surface, a cylindrical outer peripheral surface formed at the large diameter end of the tapered outer peripheral surface and complementary to the cylindrical inner peripheral surface of the outer ring, a flange portion enlarged in diameter formed at the large diameter end of the tapered outer peripheral surface, nonthreaded axial holes formed through the flange portion, and an axial slit. Bolts threadedly engage with tapped ho…
