In order to secure the groove width wb of 5, the thickness of the vertical groove side plate portion 15b in the resin indoor shape member 12z of the vertical frame 12c tends to be thin, and the strength tends to be insufficient.

Therefore, as shown in FIG.
The base portions of the vertical groove side plate portions 15b in the resin indoor shape members 12z of the vertical frame 12c are reinforced by shifting the resin indoor shape members 12z a and 12b in the horizontal direction by using the generated gap 16. That is, a thick portion 17 protruding inward to reinforce the vertical groove side plate portion 15b in the resin indoor shape member 12z of the vertical frame 12c is formed integrally and continuously in the longitudinal direction. . And the upper and lower frames 12a, 1
While the end of the metal room outer material 12x of 2b is abutted against the inner bottom (bottom) 15c of the vertical groove 15 of the vertical frame 12c,
A gap 16 is formed between the end of the indoor room material 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, into 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.
a and 12b are fitted in the end portions of the vertical frame 12c, and a thick portion 17 protruding into the inside of the vertical groove 15 is provided at the base of the vertical groove side plate portion 15b in the resin indoor shape member 12z of the vertical frame 12c. In addition, the strength of the vertical groove side plate portion 15b in the resin indoor shape member 12z of the vertical frame 12c can be improved. Moreover, the upper and lower frames 12

The gap 16 is formed between the deep portion 15c of the vertical groove 15 and the thick portion 17 by abutting the end of the resin indoor shape member 12z of FIG. 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 exterior member 1x and a metal room 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, the heat insulation can be improved. In particular, the rails 8a and 8b of the outer sash 3 are integrally formed with the metal room outer member 1x of the upper and lower frames 1a and 1b, and the rails 7a and
7b is integrally formed with the metal indoor profile 1y of the upper and lower frames 1a, 1b. The fin 10b which receives the outer sash 3 when fully closed is integrally formed with the metal chamber outer material 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 integrally formed to extend from the metal room outer material 1x of the vertical frame 1c, the wind pressure acting on the shojis 2 and the load of the shojis 2 and 3 are received by the metal profile. And strength such as wind resistance can be improved.

In this way, the wind pressure and load are received by the metal profile,
Because it is not received at 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 and 1d of the four-sided frame 1 have a composite structure in which the metal room outer shape member 1x and the resin room shape member 1z are connected, and the upper and lower frames 1a, 1d are formed.
b denotes a heat insulating structure in which a metal room exterior member 1x and a metal room member 1y are connected via a heat insulating bridge 4. Resin covers 9a to 9d are provided on the exposed surfaces of the upper and lower frames 1a and 1b. Therefore, it is possible to realize indoor resin (all appearance is made of resin) on the indoor side, and since the part exposed on the indoor side is all resin, dew condensation hardly occurs, there is warmth, and patterns such as woodgrain Colors can be easily incorporated, and decorativeness can be improved.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments, and various design changes and the like can be made without departing from the gist of the present invention. Is possible. For example, in the above-described embodiment, a sliding window sash having two inner and outer shojis in a four-sided frame is illustrated, but three or more, for example, four inner and outer shojis may be provided in a four-sided frame. In the above-described embodiment, an example is shown in which the present invention is applied to the outer sash of a sliding window sash. However, the present invention may be applied to an inner sash.
