This creation system provides a kind of Wheel structure of wheelchair,Espespecially a kind of push wheel chair person can save outside force,Also the person foot that can prevent wheelchair because swing displacement it is improper due to collide accident innovation structure design； Thereby enable this creation by because the Hou wheel unary system be can steering structure,Wheel units are structure in stays,So that user system drives the wheel units to turn to Hou wheel unit,In other words,The Wheelchair structure circumflex branch point of this creation ties up to what wheel units and makees rotation,And revolve using Hou wheel unit as swing end,It is outer to save force that push wheel chair person can reduce torque when turning to,Also the person foot that can prevent wheelchair collides epigenesist of anticipating because swing displacement is improper.本創作係提供一種輪椅之輪體結構，尤指一種推輪椅者可節省施力外，亦可防止坐輪椅者腳部因旋擺位移不當而發生碰撞意外之創新結構設計；藉此令本創作藉由因該後輪單元係為可轉向結構，前輪單元為無法轉向結構，俾使用者係以後輪單元驅動該前輪單元轉向，換言之，本創作之輪椅結構旋支點係在於前輪單元作自轉，並以該後輪單元為旋擺端作公轉，推輪椅者轉向時可減少力矩來節省施力外，亦可防止坐輪椅者腳部因旋擺位移不當而發生碰撞意外者。
