Abstract: A transmission apparatus for a leveraged wheelchair may include a wheelchair, a driving mechanism, a driving wheels set, and a transmission wheels set. The driving mechanism has a first tube and a second tube which are pivotally connected, and with the relative movements between the first tube and the second tube, the driving wheels set can have forward or rearward rotation so as to achieve bi-direction driving effect of the wheelchair. Also, the relative movement between the first tube and the second tube is cooperated with a flexible connecting head such that a handle of the wheelchair is adapted to be forward and rearward pulled or rotated axially so to achieve the moving and turning actions of the wheelchair with one hand.
