PROBLEM TO BE SOLVED: To provide a temperature response valve enabling to clean foreign matter adhering and accumulating of a valve opening without disassembling a valve casing. SOLUTION: The valve casing including a valve chamber 5 therein is formed by joining a cover 4 to a main body 3 including an inlet 1 and an outlet 2 by a screw. A spherical valve seat member 10 opening the valve opening 8 is provided in a space between the outlet 2 and the valve chamber 5. The main body 3 is provided with an opening 14 communicating to outer air with facing the spherical valve seat member 10. A bimetal lamination body 26 as a temperature sensitive member is arranged in the valve chamber 5. A valve element 13 actuated by deformation action of the bimetal lamination body 26 and opening and closing the valve opening 8 is arranged in the valve chamber 5. The spherical valve seat member 10 is rotated to a position where the opening 14 is shut off from the valve chamber 5 and the outlet 2 and the valve chamber 5 and the outlet 2 is communicated via the valve opening 8 and a position where the valve chamber 5 and the outlet 2 is shut off and the valve opening 8 is communicated to the opening 14.
