--Second embodiment--
As shown in Figure 3 (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 a single fin piece 9d extending continuously along the longitudinal direction of the glazing channel 9 is provided on the outer peripheral surface of the bottom wall portion 9a, at a position biased from the center in the forward direction to one side (the inside of the room).

In this embodiment, the glazing channel 9 is arranged on the upper frame 21 of the inner screen 2 (and the same goes for the outer screen 3) with the fin piece 9d biased toward the inside of the room, so that, as shown in Figure 3(a), the fin piece 9d is close to the outside of the inner peripheral wall (projected wall portion) 212a of the resin upper frame material 212, and an insulating space S21 is formed by the resin upper frame material 212 and the glazing channel 9 on the inside of the fin piece 9d.

In this embodiment, the glazing channel 9 is arranged with the fin piece 9d biased toward the inside of the room on the bottom frame 22 of the inner screen 2 (and the same goes for the outer screen 3), so that the fin piece 9d is close to the outside edge of the inner peripheral wall (projected wall portion) 222a of the resin bottom frame material 222, as shown in Figure 3(a), and an insulating space S22 is formed by the resin bottom frame material 222 and the glazing channel 9 on the inside of the fin piece 9d.

In this embodiment, the glazing channel 9 is positioned on the door end frame 24 of the inner door 2 (and the same goes for the outer door 3) with the fin piece 9d biased toward the inside of the room, so that, as shown in Figure 4, the fin piece 9d is close to the outside edge of the inner wall (projected wall portion) 242a of the plastic door end frame material 242, and an insulating space S24 is formed by the plastic door end frame material 242 and the glazing channel 9 on the indoor side of the fin piece 9d.

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

--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.

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

The glazing channel 9 of this embodiment is arranged on the upper frame 21 of the inner screen 2 (as well as the outer screen 3), so that, as shown in FIG. 5(a), the central fin piece 9d 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 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, forming multiple insulating spaces S21 that are continuous in the viewing direction on the indoor side of the central fin piece 9d by the resin upper frame material 212 and the glazing channel 9.

The glazing channel 9 of this embodiment is arranged on the bottom frame 22 of the inner screen 2 (as well as the outer screen 3), so that, as shown in FIG. 5(a), the central fin piece 9d 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 on the indoor side is close to the indoor inner surface of the inner wall 222a of the resin bottom frame material 222, forming multiple insulating spaces S22 that are continuous in the viewing direction on the indoor side of the central fin piece 9d by the resin bottom frame material 222 and the glazing channel 9.

The glazing channel 9 of this embodiment is arranged on the door frame 24 of the inner door 2 (as well as the outer door 3), so that, as shown in FIG. 6, the fin piece 9d near 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 indoor side wall is close to the indoor inner surface of the inner wall 242a of the plastic door frame material 242, forming multiple insulating spaces S24 that are continuous in the projection direction on the indoor side of the fin piece 9d by the plastic door frame material 242 and the glazing channel 9.

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, dividing the space on the outer periphery of the glazing channel 9 into multiple parts.

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

As described above, the sash of each embodiment has at least one fin piece that is continuous 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, and air convection at the glass opening can be suppressed.

In particular, by placing the fin pieces of the glazing channel close to the inner peripheral wall (projected wall) of the resin frame material that forms the bottom of the glass frontage, 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.

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

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

In this embodiment, the glazing channel has the fins close to the bottom of the glass opening so that it can be fitted smoothly (without resistance) into the glass opening, but the fins may be abutted against the bottom of the glass opening as long as it does not interfere with the fitting of the glazing channel.

In addition, the number and position of the fin pieces on the outer peripheral surface of the glazing channel are not limited.

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 to be treated as examples.
