Abstract
A water-tight structure of a single sliding door capable of ensuring sufficient watertightness without increasing the measurement of a rise provided on a sill so as to apply an entrance. The single sliding door is composed to provide a movable door on a window frame to be able to move in the opening direction of the door and a stationary door and attachments. A pressure-equalized clearance area is formed between the sill of the window frame of the single sliding door and the stationary door and the attachments provided on the sill, and further an air-tight member is provided to divide the pressure-equalized clearance area and an inside clearance area of the single sliding door. By forming the pressure-equalized clearance area between the inside clearance area and the outside clearance area of the single sliding door in the sill portion, a difference in the pressure between the sill portion and the outside is not produced, so that rain water is exhausted by its dead load, with the result that the watertightness can be certain although a rise is formed to a smaller measurement.
