Note that the configurations corresponding to the first and second panel receiving portions according to the present invention in the upper metal frame 111 and the upper resin frame 121, and the lower metal frame 112 and the lower resin frame 122 are the same. For this reason, hereinafter, the configurations corresponding to the first and second panel receiving portions according to the present invention in the lower metal frame 112 and the lower resin frame 122 will be described.

[0048] On the lower metal frame 112, a finding wall portion 112a (finding wall portion 111a in the case of the upper metal frame 111) that extends in the finding direction toward the inner peripheral side and faces the peripheral portion on the outdoor side of the panel 40 is provided. This finding wall portion 112a supports the finding surface on the outdoor side of the panel 40 and corresponds to the first panel receiving portion according to the present invention. Between this finding wall portion 112a and the finding surface on the outdoor side of the panel 40, a sealing material S and a backup material B are provided in the same manner as between the finding wall portions 113a and 114a and the finding surface on the outdoor side of the panel 40.

[0049] Further, on the lower metal frame 112, after extending in the finding direction toward the inner peripheral side, the extending end portion bends toward the outdoor side, and a finding wall portion 112b (finding wall portion 111b in the case of the upper metal frame 111) that faces the peripheral portion on the indoor side of the panel 40 is provided. This finding wall portion 112b supports the finding surface on the indoor side of the panel 40 and corresponds to the second panel receiving portion and the metal member according to the present invention. Between this finding wall portion 112b and the finding surface on the indoor side of the panel 40, a sealing material S and a backup material B are provided in the same manner as the finding surface on the outdoor side of the panel 40.

[0050] The lower resin frame 122 is provided with a resin engaging portion 122a (in the case of the upper resin frame 121, it is the resin engaging portion 121a) that extends in the prospective direction toward the outdoor side, then bends in the finding direction toward the outer peripheral side, and further bends in the prospective direction toward the indoor side. This resin engaging portion 122a is mounted so as to surround the tip portion of the finding wall portion 112b from the inner peripheral side. And the resin engaging portion 122a supports the finding surface on the indoor side of the panel 40, similar to the finding wall portion 112b, and corresponds to the second panel receiving portion and the resin member according to the present invention. Here, similar to the above-described embodiment, only the resin engaging portion 122a among the finding wall portion 112b and the resin engaging portion 122a abuts against the sealing material S.

[0051] The fitting 1A according to this modification 6 has a fireproof structure by the thermally expandable member HE, similar to the above-described embodiment. Specifically, the thermally expandable member HE is attached at the following positions (6) to (9). In FIGS. 9 and 10, the thermally expandable member HE attached at the position of (6) below is referred to as the thermally expandable member HE6, the thermally expandable member HE attached at the position of (7) is referred to as the thermally expandable member HE7, the thermally expandable member HE attached at the position of (8) is referred to as the thermally expandable member HE8, and the thermally expandable member HE attached at the position of (9) is referred to as the thermally expandable member HE9. (6) The finding surfaces facing the outdoor side facing the U-shaped space SP in which the panel 40 is received by the frame body 10 in the finding wall portion 111b of the upper metal frame 111 and the finding wall portion 112b of the lower metal frame 112. (7) In the left and right metal vertical frames 113, 114, the prospective surfaces on the inner peripheral side facing the space SP. (8) In the lower metal frame 112, the back surface that forms the front and back with the prospective surface on the inner peripheral side facing the space SP. (9) In the finding wall portion 112a of the lower metal frame 112, the finding surface facing the indoor side facing the space SP. Note that the thermally expandable member HE9 is configured to foam at a lower temperature than the other thermally expandable members HE6 to HD8. Also, when a non-fireproof structure is adopted, the above-described thermally expandable member HE is not provided.

[0052] The fitting according to the present invention includes a panel, a frame member having a first panel receiving portion that supports the finding surface on the outdoor side of the panel and a second panel receiving portion that supports the finding surface on the indoor side of the panel, and a sealing member provided at the peripheral portion of the finding surface on the indoor side of the panel. The second panel receiving portion is composed of a metal member and a resin member, supports the finding surface on the indoor side of the panel via the sealing member, and the sealing member is characterized in that only the resin member of the metal member and the resin member abuts thereon.

[0053] In the present invention, the second panel receiving portion constituting the frame member includes a metal member and a resin member. And only the resin member of the metal member and the resin member abuts on the sealing member. In other words, the metal member does not abut on the sealing member. Therefore, a heat transfer path from the outdoor side to the metal member through the panel and the sealing member is not provided. Therefore, according to the fitting according to the present invention, the heat insulation between the indoor and outdoor can be ensured.

[0054] By the way, when the metal member abuts on the sealing member, it is not preferable as a fireproof structure as shown below. That is, for example, assume that a fire breaks out on the outdoor side. In this case, heat is transferred from the outdoor side to the metal member through the frame member. And when the metal member becomes high temperature, the sealing member abutting on the metal member catches fire. On the other hand, in the present invention, since the metal member does not abut on the sealing member as described above, the ignition of the sealing member described above can be suppressed, and a fitting preferable as a fireproof structure can be realized.

[0055] Further, the present invention is characterized in that, in the fitting described above, the metal member is provided at a position that does not overlap with the sealing member in the prospective direction. In the present invention, by providing the metal member as described above, it can be provided at a position away from the sealing member from the metal member. Therefore, ignition of the sealing member described above can be further suppressed, and a more preferable fitting as a fireproof structure can be realized.

[0056] Further, the present invention is characterized in that, in the fitting described above, between the finding surface on the indoor side of the panel and the second panel receiving portion, an incombustible member is provided on the outer peripheral side of the sealing member. In the present invention, since an incombustible member is provided on the outer peripheral side of the sealing member, combustible gas generated from the panel by a fire can be sealed by the incombustible member in the panel opening (space SP).

[0057] Further, the present invention is characterized in that, in the fitting described above, between the finding surface on the indoor side of the panel and the second panel receiving portion, a heat-expandable member is provided on the outer peripheral side of the frame member in the sealing member. In the present invention, since a heat-expandable member is provided on the outer peripheral side of the sealing member, combustible gas generated from the panel by a fire can be sealed by the heat-expandable member expanded by heat in the panel opening (space SP).

[0058] Further, the present invention is characterized in that, in the fitting described above, no reinforcing member is provided on the frame member. In the present invention, since no reinforcing member is provided on the frame member, cost reduction and weight reduction of the fitting can be achieved.

[0059] Further, the present invention is characterized in that, in the fitting described above, the metal member is provided at a position overlapping in the prospective direction with respect to the sealing member. In the present invention, by providing the metal member as described above, the dimension in the finding direction where the metal member catches on the sealing member can be increased. Therefore, the wind pressure resistance performance can be improved.

[0060] Further, the present invention is characterized in that, in the above-described fitting, a gap is provided between the metal member and the resin member in at least one of the inner and outer circumferential directions and the indoor and outdoor directions of the frame member. In the present invention, since the above-described gap is provided between the metal member and the resin member, heat transfer between the metal member and the resin member can be suppressed, and the heat insulation performance between indoors and outdoors can be further improved.

[0061] Further, the present invention is characterized in that, in the above-described fitting, the frame member includes a frame member main body in which the first panel receiving portion is integrally formed, and the second panel receiving portion which is an edge that supports the finding surface on the indoor side of the panel, and the metal member engages with the frame member main body. In the present invention, since the metal member engages with the frame member main body, the wind pressure resistance performance can be improved as compared with a configuration in which the resin member engages with the frame member main body.
