Abstract
Abstract The connecting device for a wheel includes an outer ring having axial slits, an inner tapered surface, an inner threaded surface formed adjacent the maximum inside diameter end of the tapered surface, and an outer peripheral surface. A split inner ring having a tapered surface complementary to said tapered surface of the outer ring placed on the shaft and includes an annular groove formed at the maximum outside diameter end side of the inner ring tapered surface. A nut, having a threaded surface, is threadably engaged with the threaded surface of the outer ring. The nut includes annular projection fitting into the annular groove in the inner ring and has a seating surface perpendicular to the shaft.
