Abstract
A wheel nut loosening detection device including: a wheel having a wheel nut fastening unit; a hub; a wheel bolt configured to penetrate the wheel and the hub; a wheel nut fastened to the wheel bolt and configured to fix the wheel and the hub; at least one magnet mounted on the wheel nut; and a closed circuit mounted in the wheel nut fastening unit and disposed adjacent to the at least one magnet. The wheel nut loosening detection device further includes a current detector configured to output a corresponding output signal in response to a change in current in the closed circuit, and an output unit configured to output a warning signal in response to the output signal of the current detector.
