出力が得難いなどの欠点がある。Conventional engine starting devices include those that use a DC motor as the prime mover, those that use an air-hydraulic turbine, and those that use an elastic body energy storage system (recoil starter), but those that use a DC motor use a lead-acid battery as the power source. However, in systems using a pneumatic hydraulic turbine as the prime mover, the pneumatic hydraulic pressure generating device and energy storage device become large and expensive, and the control of the device becomes difficult. There are drawbacks such as being complicated.Furthermore, recoil starters have drawbacks such as difficulty in obtaining large output.
