To provide a power generator that can effectively use rotational energy of a tire and supply electric power to an electric device.A power generator 10 includes: a stator 20 fixed to a wheel 81; and a rotor 30 disposed coaxially with the wheel 81 and rotatably supported by the stator 20. The power generator 10 generates electric power by relative rotation between the stator 20 and the rotor 30, and supplies the electric power to an electric device attached to the wheel 81. The power generator 10 further includes: a blade portion 50 fixed to the rotor 30; a container portion 40 that is fixed to one of the rotor 30 and the stator 20 and houses the blade portion 50; and liquid L which is stored in the container portion 40 in an amount smaller than a volume of the container portion 40 and in which at least a part of the blade portion 50 is immersed.
