By providing the protruding portions 32a and 33a, the airtightness and heat insulating property can be ensured even when the first airtight material 24 or the like is thermally shrunk.

Further, a fourth airtight material 32 of the fourth airtight / heat insulating structure B4 and a fifth airtight material 33 of the fifth airtight / heat insulating structure B5 are provided, and further, the first airtight material 24 of the first airtight / heat insulating structure B1 is provided. If the adjacent protrusions 32a and 33a are provided so as to secure the desired airtightness and heat insulating property, it is possible to form the combined stile 10d with a smaller found width as compared with the conventional case. ..

Further, together with the first airtight material 24 of the first airtight / heat insulating structure B1, the fourth airtight material 32 of the fourth airtight / heat insulating structure B4 and the fifth airtight material 33 of the fifth airtight / heat insulating structure B5 form a heat insulating layer. In other words, the first resin material 21 is configured to be in contact with the first resin material 21, so that the first resin material 21 is in contact with not only the first airtight material 24 but also the fourth airtight material 32 and the fifth airtight material 33 in the finding direction. If the width is increased, the airtightness and heat insulating property can be further improved.

Although one embodiment of the airtight / heat insulating structure of the sash window according to the present invention has been described above, the present invention is not limited to the above one embodiment and can be appropriately changed without departing from the spirit of the present invention. ..

For example, the fourth airtight / heat insulating structure B4 and the fifth airtight / heat insulating structure B5 may be composed of a plurality of members.
For example, as shown in FIGS. 10 and 11, the intermediate rail / intermediate wall portion 20 of the upper frame 16 (lower frame 17) is insulated so as to project downward (upward) from the tip of the intermediate rail 20 in the projecting direction. A resin material 35 having excellent properties is attached, and further, the tip of the resin material 35 in the protruding direction, the upper end (lower end) of the first airtight material 24, and the upper stile 10a of one shoji 12 and the other 13 are brought into close contact with each other. A fifth airtight material (airtight piece / upper filling airtight material) 33 may be provided so as to fill the upper space surrounded by the upper member to form the fifth airtight / heat insulating structure B5. It goes without saying that the fourth airtight / heat insulating structure B4 can be configured upside down in the same manner as this.

Then, by filling and arranging the resin material 35 and the fifth airtight material 33 in the space portion in this way, it is possible to further improve the airtightness and the heat insulating property. Further, by providing the fifth airtight material 33, as shown in FIG. 11, the first airtight line R2 and the second airtight line R3 (third airtight line R4) can be connected.

Further, by providing the resin material 35 and the fifth airtight material 33, a new airtight line is formed at a plurality of portions where the fifth airtight material 33 abuts, such as the abutting portion between the resin material 35 and the fifth airtight material 33. be able to. Therefore, by providing the fifth airtight material 33 in a large size, it is possible to improve the airtightness and the heat insulating property more reliably and effectively while keeping the combined stile 10d small.

Further, as shown in FIG. 10, it is conceivable that the position of the airtight line (broken line) may change due to, for example, the position of the first resin material 21 attached to the other shoji 13 being displaced due to a construction error or the like. By providing the fifth airtight material 33 together with the first airtight material 24, the airtight line of this portion will not be displaced, and highly reliable airtightness and heat insulating performance can be exhibited.

Further, as shown in FIG. 12, the frame body 15 is provided with an upper rail (or lower rail: intermediate wall portion) 20 that supports the upper side (or lower end side) of each shoji 12 and 13 so as to be slidable. When the upper frame 16 (or lower frame 17) is configured, the airtight material 36 is attached to the upper stile 10a (or lower stile 10b) of each shoji 12 and 13, and the tip is attached to the upper rail (or lower rail) 20. The portions may be crimped to form an airtight line.

In the present embodiment, the first airtight material 24 is brought into close contact with the first resin material 21 of the other combination stile 10d, but the first airtight material 24 is brought into close contact with the aluminum portion (metal part) of the combination stile 10d. It is also conceivable to bring it into contact with. Also in this case, as in the present embodiment, the expected direction can be reduced because the airtight line is displaced.
