MOUNT-REMOVAL DEVICE OF SLIP STOPPER FOR WHEEL

PURPOSE:To form the above described convenient device obtaining a slip preventive effect by such means that at normal time slip preventive fittings are placed in a contactless state to the wheel of an automobile while at snowfall time the slip preventive fittings are contacted by the one-way turning operation of a hook ring. CONSTITUTION:A center pin 2 is mounted to the center of a wheel 1, and a pulley 3 is rotatably mounted to this pin. A rotary guide 4 and support 14 are rotatably mounted to the pulley 3, and plural slip preventive fittings 6 are mounted to the periphery of the guide 4. Further plural moving metal fittings 7 are provided to the periphery of the guide 4, and the neighboring metal fittings 7 are linked by springs 9 to each other. Still further a hook ring 5 is rotatably mounted to the guide 4, and the both 4 and 5 are connected by a spring 13. Then the above described pulley 3 and the moving metal fittings 7 are connected by an elastic cord 10, and the cord 10 is wound to the pulley 3 by rotating the pulley 3, in this way, the moving metal fittings 7 are spread to the periphery of the guide 4.
