PROBLEM TO BE SOLVED: To provide a three-way valve in which drive power of a valve body is kept low, and fluid leakage caused by mixed foreign matter can be effectively prevented.SOLUTION: The three-way valve 1 is provided which includes a valve boy 2 having a protruded surface in an arch shape formed by an elastic body 21, a valve body 3 having a valve chamber 3a accommodating the valve body in a rotatable manner, and an inlet port 4a and two outlet ports 5a, 6a communicated with the valve chamber, and in which a state where the elastic body slides on an inner face 3b of the valve chamber to close either of the two outlet ports and to open the other, and a state where the one outlet port is opened and the other outlet port is closed are switched, and in the three-way valve, at an intermediate opening in the middle of switching, one end of both ends of the elastic body protrudes to either outlet port of the two outlet ports, and the other end protrudes to the other outlet port. The elastic body may be biased by a coil spring 9 to the inner face of the valve chamber, the valve body may rotate in the valve chamber by rotation of a rotating shaft 8, and a plurality of coil springs may be juxtaposed in the axial direction of the rotating shaft. |
