Claims

[Claim for Utility Model Registration] An axial taper whose width increases inward from both ends at the position of minimum wall thickness of a cylindrical eccentric ring whose outer circumferential surface is eccentric with respect to the inner circumferential surface into which the shaft is fitted. The inner race has a shaped slit, and the wall thickness of a cylindrical eccentric ring in which the outer circumferential surface that fits into the boss hole of the rotating body is eccentric with the same amount of eccentricity as the inner race with respect to the inner circumferential surface that fits on the inner race. An outer lace with an axial tapered slit whose width decreases inward from both ends at the maximum position, an inner taper key and an outer taper wedged into the slits of the inner lace and the slit of the outer lace, respectively. a pair of composite keys in which the keys are formed vertically and integrally, and screw holes with opposite threads are formed coaxially in the axial direction; and a bolt with opposite threads that is screwed into both the screw holes. A fastening device for a shaft and a rotating body, characterized in that the shaft and the rotating body are fastened or unfastened by moving a pair of compound keys in mutually opposite directions by fastening a bolt.
