<p><P>PROBLEM TO BE SOLVED: To provide a roof structure which has strength as uniform as possible without reducing manufacturability, and ensures drainage without giving discomfort to a crew and passenger even when rainwater pools. <P>SOLUTION: The roof structure CB includes a main plate P and a projected part W. The projected part W includes: a first projection part group Wa having a plurality of first projection parts Waa intermittently projecting along a longitudinal direction, and first flat parts Wab; and a second projection part group Wb having a plurality of second projection parts Wba intermittently projecting along a longitudinal direction in positions different from those of the first projection parts, and second flat parts Wbb. When a side structure of the other side is viewed through from a side structure of the one side of the main plate P, the first flat parts Wab are formed in positions overlapping the second projection parts Wba, and the second flat parts Wbb are formed in positions overlapping the first projection parts Waa. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
