To provide a reliable generator for cock by restraining excessive force from working on a sliding section between a moving blade and a bearing.
This generator is equipped with a shaft member which is provided in roughly parallel with a water supply passage rotatably around the shaft member, a bearing which supports the moving blade in the axial direction of the shaft member, a magnet which is provided to surround the moving blade and is rotatable with the moving blade, a coil which is provided outside the water supply passage, and a yoke which has a plurality of inductors being provided apart in its circumferential direction and facing a magnetizing face made at the axial end face of the magnet so as to form magnetic flux interlinked with the coil. The direction of the force causing a magnet being energized to the side of an inductor by magnetic attraction working between the inductor and the magnet and the direction of the energizing force that the moving blade receives from the flowing water flowing in the water supply passage are reverse.
