NUT CAP AND NUT LOCKING TOOL

WIPO Patent Application WO/2024/019104

A1

The present invention addresses the problem of assuredly preventing nuts from loosening and eventually falling off under the circumstances where intermittent shocks, vibrations, and the like continue.　The present invention pertains to a nut cap 20 which is fitted to the outer circumference of each of a plurality of nuts 6 that are screwed onto bolts 2 protruding from a rotating hub 1 so as to mount a rotary body 3 to the rotating hub 1.　An engagement groove 10 that is formed in the lateral circumference surface of each of the nuts 6 extends along the rotational direction of the nut. Under a fastened state, the engagement grooves 10 of the nuts 6 arranged at a regular interval along the circumferential direction about the rotational center of the rotary body 3 has a binding band 11 fitted therein from the radially outer side to thereby be tightened in a loop shape. The nut cap 20 has formed, at two or more positions, openings 22 that allow the binding band 11 fitted in the engagement groove 10 of the corresponding nut 6 to pass therethrough.
