Zusammenfassung:	Provided is a rotary valve which uses a seal member having a shape in which a plurality of functions is integrated. The rotary valve includes a rotor 1, and a casing 2 including a rotor accommodating space 2a that accommodates the rotor 1. A rotor opening 15 which is a passage of cooling water is provided in the rotor 1. Openings 25a and 26a which communicate with the rotor opening 15 are provided at positions of an inner circumferential surface of the rotor accommodating space 2a which oppose an outer circumferential surface of the rotor 1. Seal members 77 are provided to extend from the openings 25a and 26a toward the rotor 1. A tip end abutting portion 80 of the seal member 77 which abuts on the rotor 1 includes an inwardly curved portion 81. The inwardly curved portion 81 functions as a seal and also functions as a spring. The inwardly curved portion 81 is narrowed inwardly toward a tip end side, and is curved to be folded back.
