Abstract
In an engine used for a portable working apparatus such as a brush cutter, there are arranged a drive gear rotated by a starter motor, and a driven gear engaging with the drive gear and connected to a crankshaft through a nonreturn clutch. The driven gear is fixed to the crankshaft until the starter motor starts the engine and released from the crankshaft after the start of the engine and after a rotational speed of the crankshaft exceeds that of the starter motor.
