To provide a compact air supply device minimizing inertia moment of the overall wheel including an air supply device as much as possible, and capable of being stored in a limited space within a wheel.SOLUTION: An axis 68 of a first cylinder 61 is disposed near a rotation axis 9 of a wheel 2, and a straight line 7 including a common perpendicular of the axis 68 of the first cylinder 61 and the rotation axis 9 passes through a sliding range 69 of a first piston 71. A second cylinder 62 and a second piston 72 have the same structure as these. Furthermore, the first cylinder 61 and the second cylinder 62 are disposed at positions that are point symmetric with respect to the rotation axis 9. Therefore, a large number of members configuring an air supply device 1 can be arranged together around the rotation axis 9.SELECTED DRAWING: Figure 8 【課題】空気供給装置を含む車輪全体の慣性モーメントを可及的に小さくするとともに、車輪内の限られた空間に収容することのできるコンパクトな空気供給装置を提供する。【解決手段】第１シリンダ６１の軸線６８を車輪２の回転軸９近傍に配置するとともに、第１シリンダ６１の軸線６８と回転軸９との共通垂線を含む直線７が、第１ピストン７１の摺動範囲６９を通るよう構成している。第２シリンダ６２、第２ピストン７２も、これらと同様の構成である。さらに、第１シリンダ６１および第２シリンダ６２を、回転軸９に対して点対称の位置に配置するよう構成している。このように構成することで、空気供給装置１を構成する多数の部材を回転軸９まわりにまとめて配置することができる。【選択図】 図８
