As shown in 5, it is set to be lower toward the left side.

In this state, as shown in FIG. 6, both ends of the beam 12 in the longitudinal direction are welded to the L angle 46 to be integrated (roof frame 48). As a result, the plurality of beamlets 12 are arranged in a state of being inclined along the arrangement direction of the beamlets 12, and it is possible to provide a so-called water gradient in the roof frame 48.
