PROBLEM TO BE SOLVED: To obtain an exhaust structure in which maintenance work of the attachments of an weather cover can be carried out easily in safety from the indoor side by disposing the weather cover on the outdoor side of an opening in the outer wall and hinging a pressure fan disposed on the indoor side. SOLUTION: A frame 11 fixed with a pressure fan 10 is hinged 13A, at one side end part thereof, to one side end part of a fixing frame 13 fixed to an outer wall 1 on the indoor side thereof and fixed, at the other side end part, is fixed removably by means of a fastener 14, e.g. a bolt. The frame 11 is provided with a handle 15. In such an exhaust structure, the pressure fan 10 is turnable horizontally through a hinge 13. When the fastener 14 is removed, the pressure fan 10 can be separated from the opening 2 in the outer wall 1 and maintenance work of the attachments of an weather cover 3, e.g. an insect- proof net 5 or fire damper, can be carried out easily in safety from the indoor side through the opening 2. |
