PURPOSE: To improve watertight performance. CONSTITUTION: A wall edge drip structure where a facing material is fitted through an air permeable bedding material 2 provided on the surface of a wall bed 1 comprises a wall edge drip 7 provided with a longitudinal piece interposed between the air permeable bedding material 2 and the upper side of the facing material 3 and a lateral piece 9 projected from the upper side of the longitudinal piece 8 toward the outdoor over the thickness of the facing material 3 in such a manner as to cover the upper end of the facing material 3. Even if water such as rainwater or the like flows along the surface of the facing material 3 toward the upper end of the facing material 3, the water is prevented from entering the ventilation space formed on the indoor side by the air permeable bedding material 2 by the wall edge drip 7 so as to improve watertight performance. |
