PROBLEM TO BE SOLVED: To provide a resin fitting that suppresses deformation of a tip in the lengthwise direction in an out-of-plane direction by making the reinforcing member thermally elongate and warp due to a fire, thereby enhancing the flame-shielding property.SOLUTION: A resin vertical frame member 2a of a frame body 2 of a resin fitting has a sash supporting part 22 and a protrusion 21 in an out-of-plane direction, with an interval in between, and a metallic reinforcing member 4 is inserted and fitted in a first hollow part 28 of the sash supporting part 22 while a metallic supporting member 5 is inserted and fitted in a second hollow part 27 of the protrusion 21. By connecting an end in the lengthwise direction of the reinforcing member 4 and an end in the lengthwise direction of the supporting member 5 with a connecting member 6, deformation at the end in the lengthwise direction of the reinforcing member 4 in the out-of-plane direction is suppressed, when the reinforcing member 4 is heated at a time of fire. Spreading of the fire through a space between the sash and the sash supporting part is also suppressed, thereby enhancing the flame shielding property. |
