An anti-slip structure for wheels on slope is disclosed, which is composed of a balance set, a pendulum, a wheel hub, and a round chassis. The balance set, the pendulum and the wheel hub are arranged on the round chassis, and a locking fastener is used to lock and fasten the aforementioned members so as to fix the balance set and allow the pendulum to change position whenever the wheels go up or down. The balance set has an anti-slip section that abuts against an inner ring of the wheel hub, so as to provide resistance that prevents the wearer from encountering danger caused by an over-speed of the wears foot range during going down a slope, or to generate a ratchet effect that prevents the wheels from backward slipping caused by insufficient pushing force during going up a slope. The invention is able to automatically rotate the relative position of the balance set and the pendulum in a human-based manner according to the change of upslope/downslope inclination, thereby enabling a wheel object installed with the structure of the invention to automatically produce a brake resistance effect.一種斜坡輪子止滑結構,係由一平衡組件、一擺錘、一輪轂及一圓底盤所組成,將該平衡組件、該擺錘及該輪轂設置於該圓底盤上,並利用一鎖固件鎖固上述構件使其固定該平衡組件及該擺錘會隨著輪子上、下坡而產生位置改變,該平衡組件上之一止滑部會抵頂在該輪轂之一內圈上,進而提供一阻力讓下坡時速度不至於超過使用者腳程而產生危險,或上波時產生的棘輪作用能避免上坡推力不足導致輪子向後滑動,本發明提供人性化自動依據上、下坡度的改變而轉動該平衡組件及該擺錘的相對位置,進而使裝設有本發明之輪子物品能自動具有剎車阻力之效用。10‧‧‧平衡組件101‧‧‧止滑部12‧‧‧擺錘121‧‧‧重力調整塊14‧‧‧輪轂161‧‧‧第一透孔162‧‧‧第二透孔163‧‧‧通孔18‧‧‧圓底盤181‧‧‧第一柱體182‧‧‧第二柱體20‧‧‧鎖固件231‧‧‧第一延伸部232‧‧‧第二延伸部241‧‧‧凸部242‧‧‧凹部
