Claims

[Scope of utility model registration request]

In a device in which a rotating body such as a flywheel is attached to an end of a rotating shaft, a mounting portion having a convex cross section having a small diameter portion and a large diameter portion concentric with the rotating shaft is provided at the end of the rotating shaft, and the small diameter A central female thread with a tapered part is formed in the center of the part, and a female mounting thread for fixing the rotating body to be attached is formed in the large diameter part. A fitting hole into which the large diameter portion is fitted, and a large diameter recess into which the large diameter portion is fitted are formed, and a through hole for a tightening bolt which is screwed into the mounting female screw is formed in the large diameter recess. When fixing the rotated object to the rotating shaft mounting part with a tightening bolt by fitting the hole and large diameter recess into the small diameter part and large diameter part of the mounting part, respectively, screw the tapered bolt into the center female thread of the small diameter part. A mounting mechanism for mounting a rotating body such as a flywheel to a rotating shaft, characterized in that the small diameter portion is mounted in close contact with the inner diameter of the fitting hole by expanding the outer diameter of the small diameter portion by tightening the fitting together.
