PROBLEM TO BE SOLVED: To smoothly perform lock/unlock in a sheet slide device provided with respective sheet slides on the outerside and on the inner side on different height by specifying the shape of first and second arms of the loop handles operating the lock levers of the respective sheet slides. SOLUTION: Sheet slides 101, 107 on the outer side and the inner side are constituted of lower rails 103, 109 and upper rails 105, 111 movably engaged with the respective ones, and the inner side sheet slide 107 is provided on the higher position than the outer side sheet slide 101. For operating the lock levers 117, 119 of the respective sheet slides 101, 107, a loop handle 129 is provided. In this case, when the loop handle 129 is rotated between the lock position and the unlock position, arm parts 129a, 129b are set so that the loci of both are intersected when the rotational loci of the extreme end parts of the respective arm parts 129a, 129b on the inner side and the outer side are projected on the same plane.
