ABSTRACT:
An apparatus for preventing cutting of a spiral spring for an engine starter includes a rope reel to be rotated by a rope rounded thereon, a spiral spring to be wound up by the rope reel in order to accumulate a power therein, an engine starting pulley driven by the power accumulated in the spiral spring, and a device for preventing the spiral spring from being cut due to an overwinding. The device has a projection which projects from an outer peripheral surface of the engine starting pulley when the spiral spring is wound up fully by the rope reel and an outer diameter of the spiral spring is reduced, and an engaging device which is provided on the rope reel and which engages the projection.
