The auxiliary self-propelled device of the new vehicle,It contains a fixed support provided on the vehicle,A connecting rod pivoted on the fixed support,At least one power source fixed on the fixed support,And at least one actuator set on the connecting rod and connected with the power source,And the said actuator group has a body connected with the power source and fixed on the connecting rod.1. A control part that can drive the power source；2. Pedals on both sides of the body；And at least one rotating wheel pivoted at the lower end of the body；Therefore,The vehicle pusher may stand on such steps,The rotating wheel is used for rotation.To move the vehicle by pushing it,Therefore, the turning wheel can reduce the physical consumption of the vehicle pusher.And greatly improve the moving range of the vehicle.More convenient operation.本新型載具之輔助自走裝置，其包含有一設於該載具上之固定支架，一樞設於該固定支架上之連接桿，至少一固設於該固定支架上之動力源，以及至少一設於該連接桿上且與該動力源連接之作動組，而前述該作動組具有一與該動力源連接且固設於該連接桿上之本體，一可驅動該動力源之控制件，二設於該本體二側之踏板，以及至少一樞設於該本體下端之轉動輪；是以，該載具推移者可站立於該等踏板上，利用該轉動輪進行轉動，以推移該載具進行移動，該轉動輪故可減少該載具推移者體能之消耗，且大幅提升該載具移動範圍，更增加行動之便利性。
