る構造となっている。2. Description of the Related Art Conventionally, a raising / lowering window for opening and closing a shoji screen in the vertical direction has been known. With this type of raising and lowering window, as shown in FIG.
On both sides of 0a are provided inward-latch latch devices 61, 61 that can be engaged with and disengaged from the window frame, respectively. This inward-latch latch device 61 is normally engaged with the window frame to engage with the indoor shoji 60.
The up-and-down movement of the inside sliding door can be tilted toward the indoor side around the lower frame by rotating the lower frame as the center of rotation by releasing the engagement with the window frame when cleaning the glass. In many cases, as a structure, as shown in FIG. 11, a latch piece 62 biased and held on the window frame side is provided, and a grip portion 62a of this latch piece 62 is gripped to resist the biasing force on the retracted side. It is structured so that the engagement with the window frame is released by pulling it in.
