A gap 16 is formed between the end of the indoor room member 12z of the upper and lower frames 12a and 12b against the deep portion 15c of the vertical groove 15 by abutting against the thick portion 17. Since the gap 16 penetrates in the vertical direction of the upper and lower frames 12a and 12b, it is possible to drain dew condensation and the like accumulated on the upper surfaces of the upper and lower frames 12a and 12b. Therefore, since the gap 16 serves as a drain hole, there is no need to separately process the drain hole in the upper and lower frames 12a and 12b. According to the sliding window sash having the above structure, the sliding doors 2 and 3 are provided in the four-sided frame 1 composed of the upper and lower frames 1a and 1b and the left and right vertical frames 1c and 1d so as to be freely opened and closed. Is a four-sided frame 12 composed of upper and lower frames 12a and 12b and left and right vertical frames 12c and 12d, in which a panel, for example, a multi-layer glass 13 is fitted. At least one of the vertical frames 12c and at least one of the upper and lower frames 12a and 12b ( In the illustrated example, both the upper frame 12a and the lower frame 12b) are formed by joining a metal room outer shape member 12x and a resin room shape member 12z, and are inserted into the vertical grooves 15 of the vertical frames 12c and 12d.

The gap 16 is formed between the end portion of the resin-made indoor shape member 12z of FIG. 2b and the deep portion 15c of the vertical groove 15 by abutting the end portion of the interior room material 12z on the thick portion 17; Drainage becomes possible, and drainage processing in the upper and lower frames 12a and 12b becomes unnecessary. The upper and lower frames 1a and 1b of the four-sided frame 1 have a heat insulating structure in which a metal room outer shape member 1x and a metal room shape member 1y are connected via a heat insulating bridge 4. The vertical frames 1c and 1d are made of metal. Because of the composite structure in which the room exterior member 1x and the resin room member 1z are combined, heat insulation can be improved. In particular, the rails 8a, 8b of the outer sash 3 are formed integrally with the metal room exterior material 1x of the upper and lower frames 1a, 1b, and the rails 7a,
7b is integrally formed with the metal indoor profile 1y of the upper and lower frames 1a and 1b, and the fin 10b which receives the outer sash 3 when fully closed is integrally formed with the metal chamber outer member 1x of the vertical frame 1d, and the inner sash 2 is entirely formed. Since the fin 10a received at the time of closing is formed so as to extend integrally from the metal room outer material 1x of the vertical frame 1c, the wind pressure acting on the shoji 2 and the load of the shoji 2 and 3 are received by the metal profile. And strength such as wind pressure resistance can be improved. In this way, the wind pressure and load are received by the metal profile,
Because it is not received in the resin part (resin profile), it is not necessary to increase the thickness of the resin part even though it is a four-sided frame 1 having a composite structure, unlike the conventional four-sided frame having a composite structure. The expected dimensions of the four-sided frame 1 in the indoor and outdoor directions can be reduced. Further, as described above, the vertical frames 1c, 1d of the four-sided frame 1 have a composite structure in which the metal room exterior material 1x and the resin room shape material 1z are combined, and the upper and lower frames 1a, 1
