<p>The present invention relates to a loosening prevention nut wherein the inner circumference of a body is threaded, wherein a breaking groove is formed on the outer circumference of the body in a circumferential direction to break the body into an upper nut part and a lower nut part, wherein one or more through-holes are formed through the breaking groove in a radial direction to facilitate the breakage. According to the present invention, the upper and lower nut parts are integrated with each other to facilitate the coupling in order to improve work efficiency; the center of the body breaks when a certain amount of torque is applied to prevent the upper and lower nut from being loosened from each other by friction to the coupling surface; and a fastening force to a bolt increases as part of the broken part burrows into a gap on a screw part to be pressurized in order to prevent the natural loosening caused by mechanical vibration and the like.</p> |
