Claims

[Scope of Claim for Utility Model Registration] A lock nut for fixing a member attached to the rotating shaft, the lock nut having a threaded part on the inner circumferential surface to be screwed into the male threaded part of the rotating shaft, wherein the slot extending from the threaded part to the outer circumferential surface is circular. An inner nut is formed intermittently in the circumferential direction and has an annular tapered surface near the outer edge of one end surface, and a recess into which the inner nut is fitted from the axial direction, and a recess from the inner circumferential surface of the recess. An outer nut having a plurality of screw holes equally spaced around the circumference extending over the outer circumferential surface;
A lock nut comprising: a set screw that is screwed into the screw hole of the outer nut and has a tapered portion at its tip that is pressed against the tapered surface of the inner nut.
