PROBLEM TO BE SOLVED: To provide a wheel hub having an air automatic feed device capable of providing the air automatic feed device and other devices without impairing their functions in the hub in which it is less probable that water such as rain water or the like is intruded into a pneumatic tire when air is fed to the pneumatic tire by the air automatic feed device. SOLUTION: The inside of the hub body 102a is divided to an air feed chamber 112 and an other device storage chamber 113 by a division member 120. The air feed chamber 112 feeds air in the air feed chamber 112 upon rotation of the hub body 102 relative to an axle 101 by communicating with an air feed part 10a of the air automatic feed device 10 through a first air passage 51. Whereas, an interior speed change device 200 is stored in the other device storage chamber 113. COPYRIGHT: (C)2005,JPO&NCIPI
