To provide a mixing faucet device capable of securing a predetermined water discharge flow rate by securing a cross section of a water discharge channel in a double-walled hose about water discharge selectively switched on an upstream side of the double-walled hose.
An inventive faucet device 1 includes: channel switching parts 28, 30 capable of selecting and switching predetermined channels among a plurality of channels; a water discharge head part 8 provided to be detachable from a faucet device body; and pipe members 16, 18. The pipe members 16, 18 are constituted of outside pipe parts 36, 74 and inside pipe parts 38, 72 respectively arranged in the outside pipe parts 36, 74 in a substantially concentric manner, respectively. Inside water discharge channels 38a, 72a are respectively formed in inner peripheral sides of the inside pipe parts, outside water discharge channels 36a, 74a are respectively formed between outer peripheral surfaces of the inside pipe parts and inner peripheral surfaces of the outside pipe parts, and at least one section 72 of the inside pipe part is formed of an elastic material which is elastically deformable by water pressure in the inside water discharge channel or in the outside water discharge channel.
