A walker is detachably joined to a wheel chair. The walker includes a first support structure and a second support structure detachably mounted to two opposite lateral sides of the wheel chair. The first support structure includes a first upper joining portion and a first lower joining portion. The second support structure includes a second upper joining portion and a second lower joining portion. The first support structure is joined to the second support structure to form the walker through the first upper joining portion joined to the second upper joining portion and the first lower joining portion joined to the second lower joining portion. The described joining portions for joining the support structures can be joined to or detached from each other. When joined to the wheel chair, the joining portions can prevent a user from falling off the wheel chair and allow the user to get on or off the wheel chair without difficulty. When connected to form the walker, the joining portions contribute to stabilization of the walker.一種結合輪椅之助行器結構,其係可拆卸地結合於一輪椅,該結合輪椅的助行器結構包括第一支持結構以及第二支持結構,分別可拆卸地安裝於輪椅的兩側邊。第一支持結構包括第一上聯結部以及第一下聯結部,第二支持結構包括第二上聯結部以及第二下聯結部,藉由該第一上聯結部結合於該第二上聯結部以及該第一下聯結部結合於該第二下聯結部,使該第一支持結構結合於該第二支持結構而組合形成該助行器。前述連接兩邊支持結構的聯結部,可以組接亦可分離,因此結合輪椅時可預防乘坐者摔落,也不妨礙乘坐者進出。組合當助行器使用時,亦兼具穩定性。100‧‧‧第一支持結構110‧‧‧第一腳架部120‧‧‧第一支持部130‧‧‧第一握把部140‧‧‧第一上聯結部150‧‧‧第一下聯結部200‧‧‧第二支持結構210‧‧‧第二腳架部220‧‧‧第二支持部230‧‧‧第二握把部240‧‧‧第二上聯結部250‧‧‧第二下聯結部1000‧‧‧結合輪椅之助行器結構2000‧‧‧輪椅2100‧‧‧本體2110‧‧‧第一側邊2120‧‧‧第二側邊2150‧‧‧第一定位部2160‧‧‧第一承載部2180‧‧‧第二定位部2190‧‧‧第二承載部2200‧‧‧輪子
