<p>The present invention relates to an anti-release lock nut and, more particularly, to perfectly preventing main nut release by using a simple operation in which an outer wall nut assembled outside the main nut is further rotated in a fastening state during bolt-nut fastening. The present invention includes a main nut (10) in which a female screw portion (11) is formed in the inner diameter and circular outer portions (12) and linear outer portions (13) are repeatedly formed in the outer diameter for screw-fastening between a bolt (30) and a male screw portion (31) and a cut portion (15) is formed on one side to allow elastic tightening and loosening; and an outer wall nut (20) in which circular inner portions (22) and linear inner portions (23) having dimensions and shapes corresponding to those of the circular outer portions (12) and the linear outer portions (13) are repeatedly formed in the inner diameter so that the main nut (10) is accommodated inside and a fastening surface (21) is formed in the outer diameter to allow engagement by a wrench tool.</p> |
