The present invention relates to an anti-loosening nut, comprising: a tightening nut formed with a screw hole on an inner diameter; a coupling nut formed with the screw hole having a diameter the same as the inner diameter of the tightening nut, and arranged on one side of the tightening unit; and a connection ring molded between the tightening nut and the coupling nut to mutually be reacted during bolt coupling of the tightening nut and the coupling nut. According to the present invention, the anti-loosening nut has the effects in improving locking functions by increasing a frictional force between the tightening nut and the coupling nut. |
