Abstract: A faucet device includes: a base member; an outer shell member; a metallic casing member that is inserted in a columnar section of the outer shell member and whose one end is fixed to the base member; a hot-water supply pipe and a cold-water supply pipe that supply hot water and cold water, respectively; a single lever cartridge provided at the other end of the casing member; connecting members provided inside the casing member, connecting the hot-water supply pipe and the cold-water supply pipe to the single lever cartridge; a fixing member fixing the single lever cartridge to the connecting members; and mechanical engagement pins. The casing member is formed of a metallic plate or pipe with a size that allows the casing member to be insertable into the columnar section of the outer shell member, and capable of retaining the connecting member in accordance with the mechanical engagement means.

Abstract: The faucet apparatus arranged inside a counter along a wall surface can be made thin in a height direction, and the counter can be made thin in the height direction. The faucet apparatus 1 includes a cold water supply pipe 6 supplying cold water, a hot water supply pipe 8 supplying hot water, a water temperature control function unit 10 capable of mixing hot water and cold water, and a flow path 14 extending from the water temperature control function unit. The flow path 14 forms a flow path crossing part 40, 240 crossing with at least any of at least the cold water supply pipe 6, the hot water supply pipe 8 or a downstream side flow path 220 on a downstream side of the outflow path while distinguishing respective inner flow paths from each other.
