The voltage is transmitted to the voltage-regulated generator 13 via the voltage regulator. As a result, the rotational force transmitted from the impeller 11 via the impeller shaft 12 is converted into electrical energy by the voltage-adjusted generator 13, and the generated power is supplied to the small storage battery 8 to charge it. .
