There is provided an axleand a wheel body rotatable with respect to the axle. An automatic air supply mechanismis provided on the wheel body. The automatic air supply mechanismhas a constant pressure maintaining sectionand a compression section. The constant pressure maintaining sectionis configured to maintain the air pressure therein at a constant value and connected to the pneumatic tire mounted on the wheel bodyin air flow communication. The compression sectioncompresses air when the wheel bodyis rotated with respect to the axleand feeds the compressed air into the constant pressure maintaining section
