<p><P>PROBLEM TO BE SOLVED: To provide a guide being easily manufacturable and capable of preventing the occurrence of jet flow in a grating mounted on a side ditch. <P>SOLUTION: The grating 1 is mounted at a position being lower than a road surface 8 in a receiving frame 5 attached to the side ditch. The receiving frame 5 has an L-shaped cross section constituted by a horizontal part 5a and a vertical part 5b, which has the same height as a bearing bar of the grating 1. Non-slip working is applied on an upper face of an upper end of the vertical part, and the guide 6 for using the upper face as a slope going up toward the road surface 8 on an outer side of the grating is integrally bent and formed by pressing. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
