ている。 The mounting structure of the drift prevention plate of the present invention is as shown in Fig. 1.
As shown in FIG. 2, the free end 11a of the drift prevention plate 11 is placed on the element 12, and its proximal end 11b is placed on the horizontal scalloped bar 14 fixed in the rear flue wall 13. It is movably connected via a stay 15 fixed to the drift prevention plate 11 to a vertical support metal fitting 16 fixed to the fin 13a in the rear flue wall 13.
