PURPOSE:To prevent leak of rain water at both end of a louver, and support the middle part of the louver so as to insure strength against snow and wind. CONSTITUTION:A shaft 12 is provided on each end of the width direction of both end parts in the lengthwise direction of a louver 11, and the shaft 12 is rotationally movably fitted to the bearing plate 14 of a hollow frame body 13. A louver engaging part 16 is provided on the upper end part of a gutter 15 in one body with the frame body 13. The louver engaging part 16 is positioned close to the one end of the louver in the width direction, and closely contacted and engaged with the inside surface part 32 of the louver 11 in the closed condition. The one end in the width direction on the middle part in the lengthwise direction of the louver 11 is supported with a middle supporting body 22 through a hinge structure 21 concentric to both end parts in the lengthwise direction. The hinge structure 21 is constituted of an intermediate shaft 23 concentically fitted to the shafts 12 on both ends of the louver, and a supporting rod 24 integrated with the center of the intermediate shaft 23, so as to form a T-shape. A cutout 25 in the range of no interference with the supporting rod 24 is provided on one part of the louver 11. |
