1. A nonslip device for a vehicle, the nonslip device comprising:
a fixing plate having a hole to be fixed to a rotation shaft extension of a vehicle wheel or to an aluminum wheel by using a bolt and a nut; a fixing circular flange and a middle spoke assembly connecting a middle circular flange and the fixing plate and lightening and strongly connecting a nonslip circular flange; the middle circular flange fixing each end of a plurality of resilient body parts provided at regular intervals in a circle; the plurality of resilient body parts provided between the middle circular flange and a frictional circular flange, and having, owing to uniform elasticity of a material, flexibility and resilience required to mount the nonslip device to the vehicle and enhance a frictional force on a slippery road; the frictional circular flange connected to each end of the plurality of resilient body parts, enhancing frictional resistance via a drainage hole formed therein and a frictional circular flange protrusion, and increasing the frictional resistance by contacting a slippery road surface in an oval shape as an outer diameter of the frictional circular flange is larger than an outer diameter of a tire; the drainage hole discharging water, snow, sand, or mud; a plurality of the frictional circular flange protrusions formed on a surface of the frictional circular flange to cause frictional resistance between the slippery road surface and the fictional circular flange; and an assisting device used to decrease an interval between the two circular flanges by hooking the assisting device on certain regions of the two circular flanges such that the certain regions of the two circular flanges are compressed with small vice pliers with respect to pliers used to mount the nonslip circular flange to the vehicle. |
