PROBLEM TO BE SOLVED: To provide a combination faucet capable of improving assemblability and productivity while securing water tightness.SOLUTION: A combination faucet 1 includes a hot water/water mixing valve unit 6, a flow rate control valve unit 12, a faucet body 2, a hot water/water mixing valve housing 4 and a flow rate control valve housing 14. A hot water passage B1 is formed which, in a state where the hot water/water mixing valve housing and the hot water/water mixing valve unit are inserted from one end side of the faucet body and also the flow rate control valve housing and the flow rate control valve unit are inserted from the other end side of the faucet body, communicates only a hot water inflow port 20 of the faucet body and a hot water side inflow port 6a of the hot water/water mixing valve unit, inside the faucet body, and also, a water passage C1 is formed which communicates only a water inflow port 22 of the faucet body and water side inflow port 6b of the hot water/water mixing valve unit. This water passage is formed between the faucet body and the flow rate control valve housing, between the faucet body and a cylindrical part 34 of the faucet body and between the faucet body and the hot water/water mixing valve housing.SELECTED DRAWING: Figure 3 【課題】水密性を確保しつつ、組立性や生産性を向上させることができる湯水混合水栓を提供する。【解決手段】本発明の湯水混合水栓１は、湯水混合弁ユニット６と、流量調整弁ユニット１２と、水栓本体２と、湯水混合弁ハウジング４と、流量調整弁ハウジング１４と、を有し、湯水混合弁ハウジング及び湯水混合弁ユニットが水栓本体の一端側から挿入されると共に流量調整弁ハウジング及び流量調整弁ユニットが水栓本体の他端側から挿入された状態では、水栓本体の内部には、水栓本体の湯流入口２０と湯水混合弁ユニットの湯側流入口６ａとのみを連通させる通湯路Ｂ１が形成され、かつ水栓本体の水流入口２２と湯水混合弁ユニットの水側流入口６ｂとのみを連通させる通水路Ｃ１が形成され、この通水路は、水栓本体と流量調整弁ハウジングとの間、水栓本体と水栓本体の筒状部３４との間、及び水栓本体と湯水混合弁ハウジングとの間に形成されている。【選択図】図３
