Annular rings are securely fixed to a shaft in a manner rendering them difficult to come loose, and easily mounted and removed. The rings, in the form of sleeves 21 and 22, are fitted over the outer periphery of a shaft 2 and fastened by a plurality of spacers in which a spacer 25 on one end of the rings is pressed by a belleville spring 27 which is compressed and deformed, and a spacer 23 on the other end of the rings is pressed by a head part 29b of a bolt 29 which is substantially parallel to an axis 0. The bolt 29 with a head is screwed to a screw hole 28a of a tightening nut 28 screwed to a screw part 2b of shaft 2.
