Abstract
There is provided a recoil starter which is capable of inhibiting settling and bending in the spiral spring of spiral spring mechanism, thus improving the durability of the spiral spring and preventing the internal hook end of the spiral spring from being easily disengaged from the core portion. The spiral spring mechanism comprises a spiral spring case placed close to the driving member, a actuating pulley placed close to the driven member, a spiral spring interposed between the spiral spring case and the actuating pulley, and means for rotating the spiral spring case only unidirectionally, wherein the outer and inner ends of the spiral spring are fastened to the spiral spring case and the actuating pulley, respectively.
