PROBLEM TO BE SOLVED: To achieve the miniaturization of a position detector for detecting the rotational position of a propeller.SOLUTION: A power generator includes a hollow speed-increasing gear, a hollow power generator, a rotary shaft, and a position detector. The speed-increasing gear is configured such that an input shaft and an output shaft are disposed coaxially with a propeller shaft, and outputs the rotation of the propeller shaft while increasing the rotation speed. The power generator is configured such that an input shaft is disposed coaxially with the speed-increasing gear, and generates power by the output of the speed-increasing gear. The rotary shaft is disposed coaxially with the speed-increasing gear and the power generator and rotates integrally with a propeller while being inserted into hollow portions of the speed-increasing gear and the power generator. The position detector detects the rotational position of the rotary shaft, thereby detecting the rotational position of the propeller. |
