舘２図Figure 1 is a side sectional view showing a conventional fire damper device;
A in the figure is a side sectional view showing the state after the temperature fuse in the normally open mechanism is blown, the opening is a vector diagram showing the closing force acting on the damper plate in this state, and Figure 3 is the fire prevention damper device of this invention. FIG. 4 is a side sectional view showing the state after the temperature fuse in the normally open mechanism is fused. In addition, the same reference numerals in the drawings indicate the same or equivalent parts, and in the drawings, 2 is a damper plate, 3 is an exhaust duct, 7 is a temperature fuse, 9 is a column, 1o is a weight, and 13 is a pivot shaft of the damper plate. It is something. In other figures, the same reference numerals indicate the same or corresponding parts. Tate 2
