<p>PURPOSE:To enable a roof panel to be opened at an arbitrary speed, by moving the roof panel in the horizontal direction along with opening working, and by opening the roof panel at the same time. CONSTITUTION:To a pair of roof panels 21 folded fitted pivotally on each other at an end section on the ridge side, the suspension lower-end section of respective string units 14 with the suspension upper-end section engaged with a suspension tool 1 is connected, and the string units 14 are almost vertically suspended so that the ridge side end section may be set to be the upper section side. Then, an upper end engagement point is moved so that an almost vertical state from the viewpoint of the side surface in the direction orthogonal to the opening direction of each roof panel 21 can be kept by the respective string units 14, and at the same time, the roof panels 21 are permitted to have a direct or indirect opening force and are opened and are arranged on a structural frame.</p> |
