SOLUTION: The feed water supply device 10 has a solenoid valve 16 provided on a channel 12 as the electrically driven valve, which is opened and closed to supply water and to stop the supply of water. An operating means (operating part) 42 is provided for opening the valve 16 and a generating means 44 such as a Peltier element or the like for generating an electromotive force by human operation is provided at the operating means (operating part) 42. The valve 16 is opened by the electromotive force generated by the generating means 44 to start the supply of water.</p> |
