Accordingly, the second side plate is inclined downward, and hence water can be completely drained out of both the transverse beam and the longitudinal beam.
Further, the longitudinal beam according to claim 1 includes the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate, and the longitudinal beam is provided on the base member through the intermediation of the inclined member having a wedge shape.
