According to the present invention, the roof is joined to both sides of the ridge member and pivots to be opened and closed. The roof pivots while not escaping from the ridge member. A dew outlet for discharging dew, gathered when the roof is opened, is formed on the ridge member. A rack in the shape of a half moon which receives rotational force of the opening and closing apparatus and rotates is joined to a lower portion of the roof. A gasket for maintaining air-tightness is installed on a lower side of the roof. A rubber gasket for pressing the covering material which covers the roof is installed. |
