The faucet device (1) of the present invention includes a device body (2); a solenoid valve (12); a spout port forming portion (44); a generator (14) for generating electrical power by rotating an impeller; a solenoid valve-side water-passage forming member (52) for guiding water to the generator; a spout port-side water-passage forming member (42) for guiding water to a spout port; a first elastic member (52a) for sealing between the solenoid valve-side water-passage forming member and the generator and allowing relative displacement therebetween; a second elastic member (42b) for sealing between the spout port-side water-passage forming member and the generator and allowing relative displacement therebetween; a third elastic member (60) for coupling the solenoid valve-side water-passage forming member and the device body and allowing relative displacement therebetween; and a fourth elastic member (58) for coupling the spout port-side water-passage forming member and the device body and allowing relative displacement therebetween.
