PROBLEM TO BE SOLVED: To provide a nonslip metal fitting attachment/detachment device for an automobile by which a nonslip metal fitting can be attached and detached to/from an external periphery of a tire without stopping an automobile by an operation from a driver's seat or the like when the automobile travels on a road face on which a snowfall and freezing mixedly exist on assumption that the device is attached to the automobile such as a truck and a bus which are attached with double-tires.SOLUTION: A reduction gear which is driven by a motor coaxially with an axle is arranged at an end of the axle which penetrates tire wheels of rear wheels. By forwardly rotating and reversely rotating the reduction gear by a radio operation from a driver's seat, a substantially L-shaped nonslip metal fitting which is fixed to a casing and an output shaft of the reduction gear becomes attachable and detachable by being deployed and closed with respect to a tire external periphery so as to open a fan with a tire as a center. Means is arranged which allows traveling by holding the closed nonslip metal fitting by a holding machine which is attached to a vehicle body.SELECTED DRAWING: Figure 1 |
