An organ type accelerator pedal includes a footplate, a housing, and a pedal arm. One end of the footplate is fixed to a floor panel, which is provided below a driver's seat. The housing is spaced apart from the footplate and fixed to a dashboard. A middle portion of the pedal arm between both ends thereof is attached to the housing by a first connector so as to elastically rotate, and one end of the pedal arm facing the footplate is attached to the other end of the footplate by a second connector so as to elastically rotate. Accordingly, it is possible to improve the durability and life span of the accelerator pedal, to significantly improve operation feeling and safety of the accelerator pedal, and to prevent operation noise from being generated.
