PURPOSE:To prevent dust pollution attributable to a spiked tire from occurring, by installing an air outlet in a part adjoining an outer circumferential surface of the tire in a car body, and blowing off warm air out of this air outlet, while embedding a pin consisting of a form memory alloy driven in the outer circumferential surfacae of the tire. CONSTITUTION:An air outlet 1 is installed in a part adjoining an outer circum ferential surface of a tire 3 in a car body, for example, in a tire house part and the like. And, the warm air produced out of a cylinder or the like of an engine is guided by a hose 2 and blown out of the air outlet 1. With this blowoff, a pin 4 consiting of a form memory alloy driven in the outer circumferential surface of the tire 3, namely, a gounding surface is raised its temperature up to some extent and embedded insid the grounding surface of the tire 3. Therefore, at an ordinary road without ice and snow, the pin 4 is accurately embedded inside, whereby any damage to the road by the pin 4 and dust occurrence are effectively preventable. |
