PROBLEM TO BE SOLVED: To provide an assembly structure of an opening frame that allows an upper frame to be fitted easily, when a gap between a depth-direction surface of a vertical frame and an edge surface of the upper frame is set to be minimal.SOLUTION: An assembly structure for an opening frame has an upper frame 12 fitted along an upper edge of an opening E through a partition wall W after fitting a vertical frame 11 on both side edges of the opening E, for constituting an opening frame 10 that slidably supports a sash 20. An elastic engaging member 40 is installed in a storage groove 11c of the vertical frame 11, the elastic engaging member being protruded from a depth-direction surface of the vertical frame 11, and allowing passage of the upper frame 12 by elastically deforming toward inside of the storage groove 11c when the upper frame 12 is moved from a lower part to an upper part with respect to the vertical frame 11, while blocking the passage by coming into contact with an undersurface of the vertical frame 12 when the vertical frame 12 is moved from the upper part to the lower part. An end of the upper frame 12 is engaged with the vertical frame 11 through the elastic engaging member 40. |
