PROBLEM TO BE SOLVED: To improve reliability of watertightness. SOLUTION: In this window frame mounting structure, a sash body is installed to a window mounting opening part 2 formed in an outside wall material 1 in a building while retracted on the interior 3 side from the outside face of the outside wall material 1. A sash fixing plate 16 for abutting and fixing a flange part 14 of the sash body is installed to the circumferential edge part on the interior 3 side of the window mounting opening part 2, while a foamed rubber watertight material 18 is installed to a part close to an insertion part 15 in the flange part 14 of the sash body, and a rubber fixed-shape sealing material 20 is installed at the substantial tip of the insertion part 15 toward the window mounting opening part 2 in an upper frame and both vertical frames in the sash body.
