To prevent a tire from falling off when a wheel nut for fastening a vehicular tire relaxes.SOLUTION: A metal rosette 3 for a left screw is sandwiched between a wheel nut 1 of a right screw and a presser nut 2 of a left screw. Teeth 4 of the metal rosette 3 for the left screw are fitted into a groove dug in the wheel nut 1 of the right screw and a groove dug in the presser nut 2 of the left screw. Accordingly, the wheel nut 1 of the right screw cannot rotate to relax, since a rotating and relaxing direction of the wheel nut 1 of the right screw and a rotating and relaxing direction of the presser nut 2 of the left screw are mutually opposed. As a result thereof, the wheel nut 1 of the right screw cannot fall off, so that the tire cannot fall off.SELECTED DRAWING: Figure 1

    【課題】自動車のタイヤを締め付けている、ホイールナットが緩み、タイヤが脱落するのを防止する事。【解決手段】右ネジのホイールナット1と、左ネジの押さえナット2の間に、左ネジ用の菊座金3が挟み込まれている。この左ネジ用の菊座金3の歯4は、右ネジのホイールナット1に掘られた溝と、左ネジの押さえナット2に掘られて溝にはまり込んでいる。それにより、右ネジのホイールナット1が回転して緩む方向と、左ネジの押さえナット2が回転して緩む方向が互いに対立する為、右ネジのホイールナット1が回転して緩む事は無い。その結果、右ネジのホイールナット1が脱落し、タイヤが脱落する事も無い。【選択図】図1
