<P>PROBLEM TO BE SOLVED: To smoothly slide an upper cover to a lower cover, even if a pressing load such as twisting in the lateral direction is applied to the upper cover. <P>SOLUTION: Three sets of rollers pivotally supported on the lower cover 4 so as to roll in a slide rail 11, are arranged in the longitudinal slide direction. The center roller 8 is brought into contact with a lower wall-side liner part 11c of the slide rail. The front roller 9 and the rear roller 7 are brought into contact with an upper wall-side liner part 11b of the slide rail 11. The rollers 7, 8 and 9 roll in the slide rail 11. The lower cover 4 has a downward regulating piece 12 and an upward regulating piece 13 inserted into the slide rail 11 so as to be adjacent to the three sets of rollers 7, 8 and 9, respectively. The pressing load to be applied to the slide rail 11 from the rollers 7, 8 and 9 is relieved by tense regulating pieces 12 and 13 in the slide rail 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
