Abstract
The present invention relates to a start device for a small-sized engine, which is capable of starting the small-sized engine in an appropriate starting time and is ultimately reduced in size and weight by a rational design. A plurality of secondary batteries is used as a power source required to drive a small-sized electric motor and a small-sized engine, and has a considerably large capacity and an extremely small size. A speed reduction mechanism that has a reduction ratio of 1/30 to 1/90 is disposed between the electric motor and a buffer/power storage section. The start device starts the engine in an extremely short time of 0.4 to 1.3 seconds. Within this range of staring time of the engine, an operator has no uncomfortable feelings.
