The cover member 4 is so formed to have a canopy portion 4a and an exterior wall portion 4b provided in connection with the canopy portion 4a. A sealing member 5 is removably disposed between the end portion of the canopy portion 4a and the exterior wall face (a) of the building A which is opposite to the end portion.
