PURPOSE:To obtain the optimum air-pressure of a tire in accordance with a situation by providing an inflating mechanism in a wheel for operating by a driver on the basis of the rotational force of running. CONSTITUTION:A projection 1 is provided in the lower part of a car-side spring. This projection 1 is operated by a driver via an operation part 7. When the projection 1 is shifted to the right, a moving part 2 of an inflating mechanism provided in a wheel 5 is automatically operated via gears, cams, and others by the rotation of the wheel 5, and consequently, air is supplied into a tire 6. Meanwhile, when the operation part 7 is shifted oppositely to the above, that is, to the left, a deflecting projection 3 is operated. Then, a deflating valve 4 in a deflating mechanism provided in the wheel 5 is opened, and the tire 6 with excessive air pressure is deflated. |
