Embodiment 2.
FIG. 8 is a front view showing a state (interior view) of a middle-sized or small-sized vertical sliding window 1', which is an opening device 2' according to Embodiment 2 of the present invention, viewed from the inside of the room.

As shown in FIG. 8, a vertical sliding window 1' provided with an opening device 2' according to Embodiment 2 of the present invention has a smaller height than the vertical sliding window 1 shown in FIG. Since the length is short, the only fastener that engages (locks) the shoji 12' with the window frame 11' is the fastener 25 provided with the handle 21, and the interlocking fastener is similar to the vertical sliding window 1 of the first embodiment. Metal fittings 23 are not used.

Instead, as a first functional component that interlocks with the rotation of the handle 21 via the interlocking member 22, an interlocking pulling fitting 26 that operates as shown in FIGS. 9(a) and 9(b) is used.

In addition, in the case of the opening device 2' of Embodiment 2 shown in FIG. An opening restricting stopper 24, which is a component, is attached, and an interlocking drawing fitting 26 is attached below the opening restricting stopper 24. Therefore, unlike the opening device 2 of Embodiment 1 described above, the interlocking member 22 is attached to the fastener 25. It is connected to the second interlocking slide plate 25h (see FIG. 6).
