Summary:An extinction device for a burner is so constructed that precision of the operation of the extinction device can be heightened even when a shape memory coiled spring (141) is used as a temperatura sensor. An extinction device comprises a swinging linkage (139) which is held free to rotate around a rotation center (145), a shape memory coiled spring (141) arranged, in an compressed condition, between the swinging linkage (139) and a second base (145b) provided on a frame (101) to generate a spring force to rotate the swinging linkage (139) in one direction around a rotation center (145), and a bias spring (143) arranged, in an expanded condition, between the swinging linkage (139) and a second fixed portion of the frame (101) to generate a spring force to rotate the swinging linkage (139) in the other direction around the rotation center (145). Such a spring is used for a shape memory coiled spring (141). The coiled spring (141) has a characteristic to give, to the swinging linkage, a torque larger than a torque given a spring force of a bias spring 143, when the circumference temperature exceeds a predetermined level.
