<P>PROBLEM TO BE SOLVED: To provide a power generator for a faucet, capable of suppressing variation in torque imposed on a moving blade even if the length of a direction substantially orthogonal to the diameter direction of a moving blade vane portion is shortened. Ž<P>SOLUTION: The power generator for a faucet includes: the moving blade having the moving blade vane portion having a rotation center substantially parallel to a water supply passage and provided on the water supply passage rotatably around the rotation center, and a moving blade diametrical outside portion provided on the diametrical outside direction of the moving blade vane portion and equipped with a magnet rotatably integrally with the moving blade vane portion; and a stator having a coil for generating an electromotive force by the rotation of the magnet, a yoke provided so as to surround the coil and a plurality of inductors protruding from the yoke and disposed to be spaced from each other. An upstream end surface of the moving blade diametrical outside portion is provided closer to an upstream side than the upstream end surface of the moving blade vane portion and a downstream end surface of the moving blade vane portion and a downstream end surface of the moving blade diametrical outside portion are provided so as to be spaced from each other so that the downstream end surface of the moving blade vane portion may be positioned closer to the upstream side than the downstream end surface of the moving blade diametrical outside portion to the extent of suppressing variation in rotation of the moving blade or noise.
