<Operation of the opening device 2 of the embodiment when a fire occurs>
Next, the operation of the opening device 2 of the embodiment when a fire occurs will be briefly described.

(If a fire breaks out indoors)
When a fire breaks out indoors and, for example, the half-open/full-open switching operation device 21c of the opening limit stopper 21, which is a resin-made indoor functional part provided on the indoor side of the door frame 12d, melts, the first heating foam material support fitting Since the external knob through-hole 23a1 (see FIGS. 6(b), 8(b), etc.) of 23a is exposed to the inside of the room, the inside of the door frame 12d can be accessed from the inside of the room via the exposed external knob through-hole 23a1. The flame enters and tries to go around to the outdoor side.

Then, first, the heating foaming materials 24a and 24b provided in the first heating foaming material support fitting 23a, which is the first space forming portion, are foamed to form the first space 23a8 (FIG. 6A) of the first heating foaming material support fitting 23a. ), and fills the external knob through-hole 23a1 communicating with the second space 23b4 (see FIG. 7A) of the second heating foam material support fitting 23b. Therefore, the flame generated inside the room is prevented from circulating to the outside through the external knob through-hole 23a1.

Further, when the fire causes the heating foaming material 24c provided in the second heating foaming material support fitting 23b to foam and expand in the second space 23b4 (see FIG. 7A) of the second heating foaming material support fitting 23b. prevents the flame generated inside the room from going around to the outside even in the second space 23b4 of the second heating foam material support fitting 23b.
