The housing 12 can be fixed in a stable state and firmly. Moreover, since the indoor side fixing | fixed part 21d is fixed in the position which opposes the opening 21e penetrated in the finding direction of the engaging member 21 in the finding direction, it is provided so that it may be located inside the opening 21e. For this reason, it is possible to make the engagement member 21 smaller than the case where the indoor side fixing portion 21d is arranged outside the opening 21e, and the engagement member 21 covers an area where foaming of the heating foam material 18 is prevented. Since it can be made smaller, it is possible to improve fire resistance. Moreover, since the engagement member 21 can be made small, it is possible to reduce cost.

  In the above embodiment, the example in which the engaging member 21 is provided on the housing 12 side and the receiving member 22 is provided on the frame body 2 side has been described. However, the present invention is not limited thereto, and the engaging member is provided on the frame body side. A receiving member may be provided.

  Moreover, although the bulging permission part with which the engaging member 21 is provided was set as the opening 21e connected to the outer periphery fixing | fixed part 21a and the engaging part 21b, it is not restricted to this. For example, it may be a notch cut out from above or below. Moreover, the bulging permissible portion may be provided so as to reach not only the outer peripheral fixing portion 21a and the engaging portion 21b but also the indoor side plate portion 21c. Thus, it is desirable that the engaging member is open in the direction of finding with sufficient strength to be drawn indoors by the receiving member after sliding with the receiving member when closing the shoji. And it is more preferable that the indoor side fixing part is provided at a position where the indoor side fixing part can be fixed at a position opposite to the bulging permissible part opened in the finding direction.

  In the above-described embodiment, the example in which the receiving member 22 has the cutout portion 22e on the indoor side has been described. However, the present invention is not limited to this, and for example, as shown in FIG. As shown in FIG. 7 (b), the receiving member 221 having the opening 22j connected to both ends 22i of the upper and lower ends 22i in the prospective direction of the upper and lower connecting plate portion 22d is bent toward the frame facing portion 2a to be attached. The receiving member 222 may be used.

  In the said embodiment, although the heating foam material 18 demonstrated the example provided in the reinforcement members 5 and 16 with which it was provided in the hollow parts 3a and 13a which the frame 2 and the housing 12 have, it does not restrict to this. For example, what is necessary is just to be provided between the reinforcing member 5 which the frame 2 has, and the reinforcing member 16 which the housing 12 has, such as the indoor facing part 13f.

  In the above embodiment, the vertical sliding window fitting 1 has been described as an example. However, the present invention is not limited thereto, and for example, a folding window, sliding window, or the like, a door, or the like may be used.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
