<;P>;PROBLEM TO BE SOLVED: To provide a skylight device with an insect-proof net solving the following problem: in a conventional skylight device with an insect-proof net, the insect-proof net is easy to be fanned up with wind and consequently remain closed while the insect-proof net is put between an opening part and a skylight because the insect-proof net is installed so as to span between the opening part and the skylight, and thereby the insect-proof net is liable to be damaged or broken. <;P>;SOLUTION: The skylight device is provided with an insect-proof net 58 blocking the entire surface of an opening part 52 and an opening/closing rod 55 for turning a skylight 54, and has the following structure: the insect-proof net 58 is connected to the opening/closing rod 55 at a connection position 59 in its inner part; the insect-proof net 58 is formed in an area larger than that of the opening part 52 so as to get loose downward from the entire periphery of the opening part 52 and the connection position 59 in an opening state; the skylight 54 turns downward so that the opening/closing rod 55 moves downward while laterally moving to the side of a turning support point axis 53 so as to get into the closed state from the opening state so that the insect-proof net 58 is housed below the opening part 52 in a closing state. <;P>;COPYRIGHT: (C)2008,JPO&INPIT
