<p>PURPOSE:To make the removal of a case attainable with a key rotated, by installing a stop piece in the backside of a partition wall inside the case, and stopping the rotation toward an unlocking direction for the case, in case of a wheel lock fitted with a built-in electronic lock. CONSTITUTION:In the case where an aluminum wheel attached to the hub of an axle is locked, first a wheel lock nut 13 is tightly screwed in one bolt among plural pieces of bolts used for clamping the aluminum wheel. Next, a case 12 fitted with a built-in electronic lock is inset in a concave 8, making it cover the nut 13, and a claw tip 17 projecting out of a partition wall 20 of the case 12 is applied to a taper surface 14 of the nut 13. Afterward, the case 12 is thrust in the inside of the concave 8 to the fullest extent with a fingertip, and the claw tip 17 is expanded wide against a spring 54 while sliding on the taper surface 14, making the tip 17 engage an annular groove 15, Likewise, a magnet 50 inside a lock plate 36 fitted with a stop piece 45 is forced into a concave 35, thus a wheel locking state is secured with the coupling of the lock plate 36 to the case 12.</p> |
