SOLUTION: A ventilating hole 12D interconnecting the inside and the outside of the back of a hut of a roof 10 with a solar battery is arranged on a roof board 12B. A cover member 20 is arranged on the ventilating hole 12D so as to cover the upper part of the ventilating hole 12D. An aperture part 23 of the cover member 20 is faced downstream, and a cable 13A which has been inserted in the aperture part 23 can be inserted in the ventilating hole 12D, in the state that the cable 13A is gently curved. As a result, when the cable 13A is pulled from the room side, the cable 13A is prevented from being strongly pressed against the peripheral edge of the ventilating hole 12D, and the surface of the cable 13A becomes hard to be damaged.</p> |
