Abstract
Abstract An internal combustion engine stop device comprises a power generation winding for generating electric power corresponding to the rotation of an engine and charging a capacitor for an ignition winding; and a stop circuit for bringing the output of the power generation winding to a short-circuit state based on the actuation of the stop switch, wherein the stop switch is of a self-reset type, and wherein the stop circuit is constituted by a self-holding circuit for keeping the short-circuit state based on the actuation of the stop switch, and a delay circuit for actuating the self-holding circuit when a switched state of the stop switch is kept for a predetermined time.
