Claims

[Scope of utility model registration request]

(1) The tip of the nut that is screwed into one of the several bolts that connect the wheel disc and hub is made into a tapered surface, an annular groove is cut, and a split wall is placed inside the cylindrical case that is placed over the nut. A lock board is placed on the front of the split wall, the core rod is inserted into the core hole of the split wall, and several blind holes are drilled at equal angles in the circumferential direction on the front of the split wall to attach the magnet. The outer end of this magnet is inserted into the recess provided on the back of the lock plate to connect the lock plate to the split wall that is integrated with the case, and a magnet is embedded to repel the magnet inside the lock plate. A square piece is connected to the core rod of the lock plate and protrudes to the rear side of the split wall, and a back plate that leaves a slight gap from the split wall is fixed to the case and filled in this gap. Insert the base piece of the nail plate which has an inverted cross-section, make a rectangular square hole in this base piece, fit the square piece of the core rod loosely, and pass the end piece of the nail plate through the notch in the back plate to insert the toe. Hook it on the annular groove of the nut with a tension spring,
A wheel nut characterized in that, as the lock plate rotates, a square piece of a core rod pries a square hole in a nail plate to remove the toe from an annular groove of the nut.

(2) The wheel lock according to claim 1 of the utility model registration, in which the square piece of the core rod and the square hole of the pawl plate have a margin set so that the rotation angle of the lock plate is equal to or less than the spacing between the magnets.
