A mounting hole for the penetrate-mounting of the movable pin operating lever is formed in the reduction case, and an elastic device for changing the friction force of the movable pin operating lever during rotation is disposed in the mounting hole. Sliding friction between the movable pin operating lever and the reduction case is changed into rolling friction so as to reduce friction resistance, and the rotation position of the movable pin operating lever can be locked effectively to ensure thorough switch between an electric state and a manual state of an electric wheelchair. 2 4 1 121 5 11 21 3 12
