PROBLEM TO BE SOLVED: To solve a problem that, since an automatic mixing valve having a temperature sensing type expansion body where all of mixing means to supplying hot water to a plurality of hot water supply passages are all excellent in intermediate action performance, the number of parts of the internal part of a mixing valve body is large and a cost of the mixing valve itself is high. SOLUTION: The mixing means for supply of hot water to a bath of a plurality of mixing means consists of a proportional type automatic mixing valve B to regulate a hot water flow passage W2 and a hot water flow passage W1 to a mixture ratio corresponding to the positions of valve bodies 16 and 17 driven by a motor A. A mixing means for supply of hot water to a general faucet for a shower and a kitchen, etc., is provided with a temperature sensing type expansion body 11. The position of the expansion body 22 is driven by a motor 20, and a valve body 21 consists of automatic mixing valve A capable of varying a mixture ratio between hot water and cold water through regulation corresponding to operation of the expansion body 22.
