Abstract: A power generator according to an embodiment includes a hollow shaped speed-increasing gear, a hollow shaped power generation unit, a rotor shaft, and a position detector. With the input shaft and the output shaft of the hollow shaped speed-increasing gear coaxially disposed with a propeller shaft, and coupled to the propeller shaft. With the input shaft of the power generation unit coaxially disposed with the speed-increasing gear, the power generation unit generates power through the output of the speed-increasing gear. The rotor shaft is coaxially disposed with the speed-increasing gear and the power generation unit and rotates integrally with a propeller while being provided in hollow portions of the speed-increasing gear and the power generation unit. The position detector detects a rotational position of the propeller by detecting the rotational position of the rotor shaft.
