NOVELTY - The generator (1) has moving blade wings (19) in moving blade (15) that are rotatably provided in water supply flow path around center axis (24). A coil produces electromotive force based on rotation of magnets (M) integrally arranged in blade. A stator (9) has mutually separated inductors (31a,32a) which are arranged so as to oppose outer peripheral surfaces of magnets with respect to water supply flow path. The downstream end surfaces of wings are arranged above downstream outer peripheral surface of blade to suppress rotation non-uniformity and noise of blade.    USE - Generator for automatic water tap apparatus installed in living space, kitchen, dining room, shower, toilet and washroom.    ADVANTAGE - The mutually separated inductors of stator are arranged so as to oppose outer peripheral surfaces of magnets integrally arranged in moving blade with respect to water supply flow path. Thus torque fluctuations received by moving blade can be suppressed, even when length of moving blade wing in direction perpendicular to radial direction is shortened and the magnetic flux from outer peripheral surface of magnet is guided to coil through inductors. The dimensions of generator and automatic water tap apparatus can be reduced along radial direction. The reliability, installation property, operability and external appearance design of automatic water tap apparatus can be improved and cost can be reduced. Predetermined electric power generation amount can be ensured stably irrespective of influence of water flow. Control unit wiring can be managed easily, pitch accuracy between inductors can be improved, core loss, increase in pulsation width, charger failure die to water-immersion and fall of average pressure torque can be suppressed and the generator output can be increased without enlarging size of generator.
