Patent ID: 7608936

Claim:
A faucet generator comprising: a rotor vane which is disposed in a water supply channel; an annular magnet which is rotatable integrally with said rotor vane; and a stator having a coil which is disposed to be opposed to an end face of said magnet that is substantially perpendicular to a radial direction, a plurality of inductors which are placed separately from one another along a circumferential direction between said end face of said magnet and said coil, and a yoke which is disposed to be continuously contacted with said inductors and surround said coil, wherein an axial direction of said rotor vane is substantially parallel to said water supply channel, end faces of said annular magnet which are substantially perpendicular to a radial direction are alternately magnetized with N and S poles along a circumferential direction of said magnet, and, in one end of said yoke that is on a side where said inductors are disposed, portions which are in a vicinity of tip ends of said inductors are formed to relatively recede from a magnetic inducible area of said magnet.
