To provide an anti-loosening device for a fastening unit of a wheel.SOLUTION: An anti-loosening device 1 is configured to be arranged within a wheel hub H along an axial direction, so that a main axis of the anti-loosening device coincides with a wheel axis W. The anti-loosening device 1 comprises: a gear 3 arranged to cooperate with inner teeth H3; an elastic element 5 extending axially with respect to the gear 3; and a coupling element 8 provided in a sector of the gear 3, and arranged to receive a corresponding fastening member 10. The anti-loosening device is arranged to create a compressed configuration, wherein the gear is decoupled with respect to the inner teeth, and is arranged within a cavity portion provided on an inner surface H2 of the wheel hub, so as to allow rotation of the anti-loosening device around the main axis. The coupling element is arranged to be radially aligned with respect to each anti-rotation sector 9 provided on a fastening unit, in such a way that in the final assembled condition, the fastening member coupled to the coupling element cooperates with the anti-rotation sector, to avoid loosening of the locking unit 2.SELECTED DRAWING: Figure 1
【課題】車輪の締結部の緩み防止装置を提供すること。【解決手段】緩み防止装置1は、緩み防止装置の主軸が車輪軸Wと一致するように、軸方向に沿って車輪ハブH内に配置されるように構成され、内側歯部H3と協働するように配置されるギア3と、ギアに対して軸方向に延在する伸縮性要素5と、ギアの区域に設けられ、対応する締結部材10を受容するように配置される連結要素8とを含む。緩み防止装置は圧縮形状を生み出すように配置され、この圧縮形状において、ギアは内側歯部に対して連結解除され、車輪ハブの内側表面H2に設けられた空洞部分内に配置され、主軸の周りでの緩み防止装置の回転が可能となる。連結要素は組み立てられた状態において、連結要素に連結された締結部材が回転防止区域9と協働して係止部2の緩みを回避するように、締結部上に設けられたそれぞれの回転防止区域に対して径方向に整列するように配置される。【選択図】図1
