ABSTRACT:
An air supply device is provided on a rotating body having an air filling portion into which air is filled. The air supply device has a device body provided with a cylinder, and a piston mounted movably in the cylinder, the device body being joined at the middle of a valve so that a through-hole is communicated to a flow passage of the valve. A direction, in which the piston is moved, corresponds substantially to a radial direction of a tire unit (wheel), and the piston can be moved by a centrifugal force, which is generated by rotation of the tire unit. A latch for latching the piston is formed below the piston in the cylinder, in which a coil spring is mounted. Also, the device body is provided with an adjusting screw, check valves, and an air filter.
