Abstract
A heat sensing device includes a heat sensing element that contacts an inner surface of a surface heater extending in an arc shape, the inner surface having the arc shape, and that senses that a temperature of the surface heater exceeds a predetermined temperature; a spring member one end of which is fixed to the heat sensing element and that presses the heat sensing element against the inner surface of the surface heater; and a supporting body that supports the other end of the spring member, the other end being away from the heat sensing element, in such a way that the other end is movable in a direction in which the surface heater extends in the arc shape.
