<p>PROBLEM TO BE SOLVED: To achieve a better drainage with a lower cost by accomplishing an easier designing of a molding die with a simplification of the die to reduce the number of parts and assembling manhour and improve working efficiency. SOLUTION: A water receiving surfaces of a top board 28, a side plate 39 and a bottom part are formed vertically to the rear of a rear plate 18 of a longitudinal container with the front thereof opened and a mounting protruded part is 37 formed at the lower end part of the rear of the rear plate 18 as protruding to a mounting surface. The rear plate 18, the top board 28, the side plate 39 and the bottom part are molded integrally making the end rims of the top board 28 and the side plate 39 parallel with a vertical surface connecting the upper end part of the rear plate 18 and the rear of the mounting protruded part 37.</p> |
