PROBLEM TO BE SOLVED: To solve a problem of extremely inefficient adjusting work through trial and error heretofore performed due to the necessity of once detaching a sliding door from a lintel groove and a sill groove to make a longitudinal adjustment of the sliding door, that is, a clearance adjustment between the sliding doors or between the sliding door and a wall surface and accurately confirming an adjusted quantity only after resetting the sliding door to the lintel groove and the sill groove. SOLUTION: An adjusting means comprising a tapered part and a sliding part is fitted between the side face upper end part of this sliding door and the side face of the lintel groove, and the adjusting means is vertically slid to easily adjust the clearance between the sliding doors and between the sliding door and the wall surface, with the sliding door set as it is to a lintel and a sill.
