PROBLEM TO BE SOLVED: To provide a mobile vehicle capable of suppressing the inclination angle of the body part to the running surface at a low level in shifting from a two-axle wheels grounded state to an erected state.SOLUTION: When a state in which two-axle wheels 22 and 23 are grounded on the running surface Sd (two-axle wheels grounded state) is transferred to a state in which the vehicle is erected on one-axle wheel 22, the body part 10 of the vehicle is rotated around a support shaft Cwith respect to the support part 21 in the two-axle wheels grounded state； an inertial force around the support shaft Cis produced by decreasing the rotation speed of the body part 10 with respect to the support part 21； and the support part 21 is rotated around the axle 22a of one-axle wheel 22 grounded on the running surface Sd by the inertial force F to transfer to the state in which the vehicle is erected on the one-axle wheel 22.【課題】２軸車輪接地状態から起立状態へ移行する際に走行面に対する本体部の傾斜角度を小さく抑えることができる移動車両を提供する。【解決手段】２軸の車輪２２，２３を走行面Ｓｄに接地した状態から１軸の車輪２２による起立状態へ移行する際に、２軸車輪接地状態において支持部２１に対して本体部１０を支持軸Ｃ２１回りに回転させ、続いて支持部２１に対する本体部１０の回転速度を低下させることにより支持軸Ｃ２１回りの慣性力Ｆを発生させ、続いて当該慣性力Ｆによって、走行面Ｓｄに接地している１軸の車輪２２の車軸２２ａ回りに支持部２１を回転させることで当該１軸の車輪２２による起立状態に移行させる。【選択図】図８Ｄ
