Claims

[Scope of utility model registration request]

In a wheel nut lock, a wheel nut that is screwed onto a bolt provided on a wheel shaft body to which a tire is screwed can be attached and detached using a key equipped with a magnet, and the cylindrical part of the rotator is attached to a nut with a thread carved on the inner wall surface. In addition to forming a space for insertion and forming an annular protrusion protruding from the periphery of the distal end of the space, a case to be fitted into the nut, and a plurality of recesses formed on the inner wall surface of the case, a rotator which is rotatably fitted to a shaft formed in the rotator and forms a flange, and a plurality of insertion holes into which magnets are inserted into the flange of the rotator;
A magnet fitted into the insertion hole, a spring that biases the magnet, a slider that rotates the rotator in the circumferential direction and slides in the axial direction, and a slider that is interposed between the slider and the case and that A spring that biases the slider is provided, and an inclined surface is formed that is connected to a guide groove that guides the slider on one side of the rotator and a groove that fits a latch on the other side, and when the rotator is biased by the spring and rotates. A wheel locking device characterized in that a slider can displace a rotator circumferentially by a cam groove, and a latch can be moved circumferentially by a sloped surface.
