<p><P>PROBLEM TO BE SOLVED: To provide a trough whose cover is hard to come off and is easy to open when a user opens it. <P>SOLUTION: This trough comprises a trough body 10, a cover 12, and a fixing tool 14. In the trough body 10, projection 16 is integrally formed from risers 16a which rise from the topsides 10a of both side walls, and overhangs 16b which extend sideward from the tops of the risers at a part in longitudinal direction. In a cover 12, a cut 18 is made in a section equivalent to the above projection 16, and also a thin part 20 lacking in the thick upper layer of the cover is made integrally next to the cut. A fixing tool 14 is made in the form of surrounding the section other than the riser 16a of the above projection 16, and it can slide longitudinally in condition that it is mounted on the top of the projection 16. The slip out of the cover l2 is prevented by sliding the fixing tool 14 and positioning its one end side on the above thin part 20. <P>COPYRIGHT: (C)2004,JPO</p> |
