Abstract: A trigger generator is incorporated in a flywheel magneto which is directly coupled to the crankshaft of an engine to be driven thereby. A plurality of rotary magnetic poles are mounted on the body portion of the flywheel to constitute a rotor, and the iron core of the trigger generator is disposed in the space defined between the magnetic poles and the hub portion of the flywheel so as to establish a magnetic path which passes through the iron core and the hub and body portions of the flywheel. The trigger generator generates an output in response to the rotation of the engine without producing any noise voltage. Ignition can be reliably attained during each rotation and a high output can be obtained even when the engine is rotating at a low speed.
