One kind looking after the structure of chair,It is that one upper bracket of what is equipped with two groups of horizontal oppositely extending seat frames and plate supporting frame,Across supporting plate before setting one on two plate supporting frame of what,The upper vertical component effect extended downwardly is equipped between two plate supporting frames and two seat frames,One lower bracket is equipped with Hou wheel carrier and two oppositely extending front wheel carriers below two what seat frames,Before,Hou wheel carrier be pivotally connected plural number respectively before,Hou idler wheel,And before what,It is equipped with two lower vertical components between Hou wheel carrier and does not combine vertical component effect on what upwards,Make to form an opening between two Hou wheel carriers and two seat frames,One back braces system removably combines on what seat frame,What back braces are equipped with a back pad,Two side of back pad is equipped with pivot joint bracket,One seat cushion what, two side middle section is pivotally connected the aforementioned pivot joint bracket of what via a driving arm respectively,It is rotated using the seat cushion relative to what driving arm,The driving arm is cooperated to be pivotally connected holder pivots with respect to what,Seat cushion can be made movable across the position set on two seat frame of what and between the position of what back pad.一種照護椅之結構，係於一上支架設有二組水平反向延伸的座墊架與托板架，於二托板架上跨設一前托板，二托板架與二座墊架之間設有向下延伸的上垂直部，一下支架設有二位於座墊架下方的後輪架及二反向延伸的前輪架，前、後輪架分別樞接複數前、後滾輪，且於前、後輪架之間設有二下垂直部分別向上結合於上垂直部，使二後輪架與二座墊架之間形成一開口，一背支架係可拆卸地結合於座墊架上，於背支架上設有一背墊，該背墊二旁側設有樞接支架，一座墊於二旁側中段分別經由一樞接臂樞接於前述樞接支架，利用該座墊相對於樞接臂轉動，配合該樞接臂相對於樞接支架轉動，可使座墊在跨設於二座墊架上的位置以及抵靠於背墊的位置之間活動。
