SOLUTION: The warehouse truck yard has a platform, a ceiling, and side walls. The airtight structure of the warehouse truck yard comprises an upper blocking means for blocking a gap between the upper part of the truck cargo chamber T and the ceiling, a side blocking means for blocking a gap between the sides of the truck cargo chamber T and the side walls, and a sheet 5, which is arranged between the end of the platform 2 at the truck side and the floor surface of an opening of the truck cargo chamber T and whose portion at the truck side can be moved up and down. The airtight structure also includes an interlocking means 6 for interlocking the truck side portion of the sheet 5 with the truck cargo chamber T which moves up and down. The interlocking means 6 comprises slide members 61 supported to be vertically movable relatively to the side blocking means 3 at the contacting part between the side blocking means 3 and the outer sides of the cargo chamber T, a detecting means 64 for detecting the height of the cargo chamber T and interlocking the slide members 61 with the the cargo chamber T moving up and down, and a locking means 65 for locking the truck side portion of the sheet 5 to a prescribed part of the slide members 61.
