ABSTRACT:
A sliding screen door in which stretching force of a wire is easily adjusted when a screen is in a stretched condition, and expansion of the screen caused by wind or the like can be appropriately suppressed without increasing operation force to be applied to an operating doorframe for the operation to stretch the screen. The sliding screen door is constructed such that wires, whose one ends are fixed to a vertical frame member are drooped in the operating doorframe via a guiding member, which is provided in the operating doorframe, after being inserted into the screen, and a sinker is dangled at tip ends of the wires. A spring member is interposed between the sinker and a contacting portion to be a rising uppermost limit of the sinker, and a wire adjusting mechanism for adjusting a length and the stretching force of the wire is installed in the vertical frame member.
