To enable a plastic frame to be removed upon replacement thereof without affecting a frame structure as much as possible and concurrently to minimize the deformation of the plastic frame due to temperature changes during normal use.SOLUTION: A composite window frame including a metal frame framed in a square shape and a plastic frame mounted on the indoor side of the metal frame, in which a screw 3 directed in the depth direction is screwed to a screw shaft part screwing piece 1a15 of the metal frame, whereas an excessive through portion 1a25 having an inner diameter larger than the outer diameter of a screw shaft portion 3b is provided on a surface of the plastic frame facing the screw shaft part screwing piece 1a15, and the shaft portion 3b of the screw screwed to the screw shaft part screwing piece 1a15 is passed through the excessive through portion 1a25.SELECTED DRAWING: Figure 1
【課題】樹脂枠の交換に際し、躯体に極力影響を与えることなく樹脂枠を取外すと共に、通常の使用時における温度変化による樹脂枠の変形も極力抑える。【解決手段】方形状に枠組みされる金属枠と、その金属枠の室内側に取付けられる樹脂枠とを備えた複合窓枠であって、金属枠のネジ軸部螺合片１ａ１５には、見込み方向に向かうネジ３が螺合する一方、樹脂枠におけるネジ軸部螺合片１ａ１５に対向する面には、ネジの軸部３ｂの外径よりも内径が大きい過大通し部１ａ２５ａが設けられており、その過大通し部１ａ２５ａにネジ軸部螺合片１ａ１５に螺合したネジの軸部３ｂが通される。【選択図】図１
