PROBLEM TO BE SOLVED: To provide a direction diverter valve which prevents forgetting to return the water flow to the original direction. SOLUTION: The direction diverter valve is provided with a first internal passage communicating with a first hole, a second internal passage which is opposite to the first internal passage and communicates with a second hole, a first valve seat formed on the rim of the first internal passage, a second valve seat formed on the rim of the second internal passage, a valve body provided movably between the first valve seat and the second valve seat and a biasing means which constantly biases the valve body to the second valve seat. At usual time the valve body is seated on the second valve seat while separated from the first valve seat by the biasing means in such way that the first hole and the third hole communicate with each other. Also while the insertion section of a flow channel connection device is inserted from the second hole through the second internal passage into the valve, the valve body is seated on the first valve seat while separated from the second valve seat in such way that the inside of the flow channel connection device and the third hole communicate with each other.
