<p>A horizontal drain includes drain main body having a pan mountable in a recess on a floor, and a drain cover unit having a horizontal cover to cover the pan. The pan has a pipe-like body connected with the pan at a downstream end of the pan in the direction of flow of rainwater. The pipe-like body extends horizontally for connection with a drain pipe and is formed with a drain bore for communication with the pan. The cover has an upper surface provided with a plurality of guide ridges which extend from an outer periphery of the cover toward a lateral center portion of the cover in the direction of flow of rainwater. Each of the guide ridges is inclined such that an upper end of the ridge is positioned away from the pipe-like body. Guide gaps for guiding rainwater into the pan are defined between the adjacent guide ridges.</p> |
