Claims

[Scope of utility model registration request]

A slit in the axial direction is provided at the position of the minimum wall thickness of the inner ring, which has a flange at one end and whose outer circumferential surface is eccentric with respect to the inner circumferential surface into which the shaft fits, and the inner ring is flange-shaped within an equal angle range from the slit. An inner race with a circumferential groove to separate it from the inner ring; an outer ring whose outer circumferential surface, which fits into the boss hole of the rotating body, is eccentric with the same amount of eccentricity as the inner ring; An axially tapered keyway for separating the outer ring is provided at the position of maximum thickness, and an expandable part is formed of a plurality of slits that enter alternately in opposite directions from both sides of the outer ring in the middle thick part equally spaced from the keyway. A tapered key that fits into the keyway; and a bolt for pushing the tapered key into the keyway, and when the tapered key is pushed in, the outer race is inserted into the boss hole of the rotating body. A fastening device for a shaft and a rotating body, characterized by being wedged between a ring and a shaft.
