[0037] In this embodiment, the glazing channel 9 is arranged with the fin pieces 9d biased toward the inside of the room on the joint frames 23, 34 of the inner and outer screens 2, 3, so that, as shown in Figure 4, the fin pieces 9d are close to the bottom of the glass openings 23a, 34a of the joint frames 34, 23, forming insulating spaces S23, S34 on the inside of the fin pieces 9d.

[0038] -Third embodiment- As shown in Figures 5(b) and 7(b), the glazing channel 9 of the sliding sash of this embodiment has a bottom wall portion 9a arranged along the bottom of the glass opening, left and right wall portions 9b, 9b extending inwardly from both the left and right ends of the bottom wall portion 9a, and glass abutment portions 9c, 9c provided on the inside of the inner ends of the left and right wall portions 9b, 9b, and four fin pieces 9d, 9e are provided continuously along the longitudinal direction on the outer peripheral surface of the bottom wall portion 9a.

[0039] The four fin pieces 9d, 9e of the glazing channel 9 consist of two central fin pieces 9d, 9d arranged toward the center on the outer peripheral surface of the bottom wall portion 9a, separated by the center line in the forward direction, and two side wall fin pieces 9e, 9e arranged outside the central fin pieces 9d, 9d, separated by the center line, and are arranged symmetrically on the left and right.

[0040] In this embodiment, the glazing channel 9 is positioned on the upper frame 21 of the inner screen 2 (and the same goes for the outer screen 3) so that, as shown in Figure 5(a), the fin piece 9d near the center on the indoor side is close to the inner surface on the outdoor side of the inner wall (projected wall portion) 212a of the resin upper frame material 212, and the fin piece 9e near the side wall on the indoor side is close to the inner surface on the indoor side of the inner wall 212a of the resin upper frame material 212, and multiple insulated spaces S21 that are continuous in the viewing direction are formed on the indoor side of the fin piece 9d near the center by the resin upper frame material 212 and the glazing channel 9.

[0041] In this embodiment, the glazing channel 9 is arranged on the bottom frame 22 of the inner screen 2 (and the same goes for the outer screen 3) so that, as shown in Figure 5(a), the fin piece 9d near the center on the indoor side is close to the outdoor edge of the inner wall (projected wall portion) 222a of the resin bottom frame material 222, and the fin piece 9e near the side wall on the indoor side is close to the indoor inner surface of the inner wall 222a of the resin bottom frame material 222, and multiple insulated spaces S22 that are continuous in the viewing direction are formed on the indoor side of the fin piece 9d near the center by the resin bottom frame material 222 and the glazing channel 9.

[0042] In this embodiment, the glazing channel 9 is positioned on the door frame 24 of the inner door 2 (and the same goes for the outer door 3) so that, as shown in Figure 6, the fin piece 9d toward the center on the indoor side is close to the outdoor edge of the inner wall (projected wall portion) 242a of the plastic door frame material 242, and the fin piece 9e near the side wall on the indoor side is close to the indoor inner surface of the inner wall 242a of the plastic door frame material 242, and multiple insulated spaces S24 that are continuous in the viewing direction are formed on the indoor side of the fin piece 9d by the plastic door frame material 242 and the glazing channel 9.

[0043] In this embodiment, the glazing channel 9 is positioned on the sash frame 23 of the inner screen 2, so that, as shown in Figure 6, the fin piece 9d near the center on the indoor side is close to the bottom of the glass opening 23a, and the fin piece 9e near the side wall on the indoor side is close along the outdoor side edge of the inner wall (projected wall portion) 232a of the resin sash frame material 232, and an insulating space S23 is formed by the resin sash frame material 232 and the glazing channel 9 on the indoor side of the fin piece 9e near the side wall. Furthermore, the fin piece 9d near the center and the fin piece 9e near the side wall are close to the bottom of the glass opening 23a of the joint frame 23, thereby dividing the space on the outer periphery of the glazing channel 9 into multiple parts.

[0044] In this embodiment, the glazing channel 9 is positioned in the joint frame 34 of the outer screen 3, so that, as shown in Figure 6, the fin piece 9d near the center and the fin piece 9e near the side wall are close to the bottom of the glass opening 34a, dividing the space on the outer periphery of the glazing channel 9 into multiple parts.

[0045] As described above, the sash of each embodiment has at least one fin piece that continues in the longitudinal direction on the outer peripheral surface of the glazing channel, and by bringing the fin piece close to the bottom of the glass opening, an insulating space can be formed between the glass opening and the glazing channel, thereby suppressing air convection at the glass opening.

[0046] In particular, by placing the fin pieces of the glazing channel close to the inner wall (projected wall) of the resin frame material that forms the bottom of the glass opening, an insulating space surrounded by members made of resin material can be formed on the indoor side of the fin pieces, further improving the insulating performance.

[0047] Furthermore, by placing the fin pieces of the glazing channel close to the outdoor edge of the inner wall (projection wall) of the resin frame material that forms the bottom of the glass opening, a large insulating space surrounded by members made of resin material can be formed, further improving the insulating performance.

[0048] In addition, by arranging multiple fin pieces of the glazing channel in a line in the projection direction, multiple insulating spaces lined up in the projection direction can be formed between the glass opening and the glazing channel, further improving the insulating performance.

[0049] In addition, in this embodiment, the glazing channel has the fin pieces close to the bottom of the glass opening so that it can be fitted smoothly (without resistance) into the glass opening, but the fin pieces may also be abutted against the bottom of the glass opening to the extent that it does not interfere with the fitting of the glazing channel.

[0050] Furthermore, the number and positions of the fin pieces provided on the outer peripheral surface of the glazing channel are not limited.

[0051] Furthermore, the fixture to which the glazing channel is attached is not limited to sliding windows, but can be used for any type of window, such as fixed windows and casement windows, as long as the window has a panel body attached. It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
