摘要：PROBLEM TO BE SOLVED: To provide a waterproof pan with a drain ditch having superior draining performance for a good water flow. SOLUTION: The waterproof pan P in a rectangularly planar shape with side walls 1 on four peripheries comprises the drain ditch 2 formed along the front edge with a ditch bottom face 2a inclined gradually lower as tending from the center of the drain ditch closer to both ends and drain ports 2b formed in the ditch bottom face 2a at both ends of the drain ditch 2. Rainwater flowing into the drain ditch 2 is divided in two with the ditch bottom face 2a inclined lower as tending from the center of the drain ditch closer to both ends and smoothly flows toward both ends of the drain ditch, and it is drained from two drain ports at both ends, producing good draining performance. Preferably, a ditch cover 7 is detachably mounted on the drain ditch. Thus, the waterproof pan P in good appearance has the drain ports or drain pipes whose wide effective areas prevent the clogging thereof with withered leaves. COPYRIGHT: (C)2005,JPO&NCIPI
