<p><P>PROBLEM TO BE SOLVED: To provide a sliding cover superior in a water-proof effect enabling continuous covering by extremely simple work and reduced in manufacturing cost. <P>SOLUTION: A gap between engaging pieces 2 at one end of a cover body 1 is made narrower than a gap between the engaging pieces 2 at the other end of the cover body. The gap between the engaging pieces 2 is formed so as to gradually expand toward the other end from the one end of the cover body 1. The gap between the engaging pieces 2 at the one end is made narrower than the gap between the engaging pieces 2 at the other end, and the gap between the engaging pieces 2 is formed so as to gradually narrow toward the other piece from one piece. One end at which the gap is narrow is set as a narrow-width end 4, and the other end at which the gap is wide is set as a wide-width end 3. The wide-width end 3 of one adjacent cover is slidably superposed on the upper face of the narrow-width end 4 of the other adjacent cover, thus adjusting the length of the cover. <P>COPYRIGHT: (C)2004,JPO</p> |
