The opening restricting stopper 2 has an operation portion 21 and a restricting arm 22 connecting the frame 0 and the shoji 1 . The operation part 21 is operated to switch the shoji 1 between a half-openable state and a fully-openable state. The operation of the operation unit 21 is performed by moving it in the right and left directions. By moving the operation part 21 to the right, the shoji 1 is switched to a half-openable state, as shown in FIGS. 1 and 2 . While the operation part 21 is fixed on the right side, the shoji 1 is held in a half-openable state, and as shown in FIG. 10, and the opening of shoji 1 is limited to half open. In other words, the limit arm 22 connects the lower frame 10 and the lower frame 11, and when the shoji 1 is in the half-openable state, the limit arm 22 and the shoji 1 are in a connected state. When the shoji 1 is in the half-openable state, the leftward movement of the operation part 21 comes into contact with the lock mechanism 3 provided on the left side of the operation part 21, and the operation part 21 cannot be moved.

As shown in FIG. 4B, the lower portion of the restricting member 31 is provided with a substantially rectangular parallelepiped contact portion 31a protruding rightward. As for the contact portion 31a, when the operation portion 21 is to be moved leftward, the right end portion of the contact portion 31a comes into contact with the operation portion 21, thereby hindering the leftward movement of the operation portion 21. . As shown in FIG. 4(b), a lock hole for a cylinder lock 32 is provided on the upper portion of the regulating member 31 so as to be exposed on the interior facing surface. As shown in FIG. 4A, the cylinder lock 32 is attached so as to overlap the exterior facing surface of the regulating member 31. As shown in FIG. When the cylinder lock 32 is locked, the contact portion 31a of the regulating member 31 is fixed at a position to the right of the cylinder lock 32. As shown in FIG. That is, the lock mechanism 3 is fixed at a position where the half-openable state of the shoji 1 is maintained, where the lock mechanism 3 abuts on the operation portion 21 to prevent the operation portion 21 from moving to the left. As shown in FIG. 4(a), a fixing portion 33 is attached to the exterior facing surface of the cylinder lock 32 so as to overlap it. As shown in FIGS. 4A and 4B, the fixing portion 33 has a rectangular shape in a plan view and a substantially L shape in a front view. The fixing portion 33 is screwed to the indoor-side facing surface of the lower frame 11 of the shoji 1 with screws 33a, 33a. As shown in FIGS. 4A and 4B, the screws 33a, 33a of the fixing portion 33 are hidden by the regulating member 31 because the regulating member 31 overlaps the interior facing surface of the fixing portion 33. As shown in FIGS.

Next, the opening and closing of the half-openable shoji 1 will be described.
As shown in FIGS. 2, 6 and 7, the lower frame 11 of the half-openable shoji 1 is always in the lower frame of the frame 0 when the shoji 1 is opened and closed by the restricting arm 22 of the opening restricting stopper 2. 10 is connected. That is, the shoji 1 and the limit arm 22 are in a connected state.
As shown in FIGS. 5(a) and 5(b), the restriction arm 22 has a horizontally long, substantially flat plate-like shape when viewed when the shoji 1 is closed, and has a support shaft 22a at its left end. It has a pin 22b at the right end. A support shaft 22 a of the limit arm 22 engages with the lower frame 10 . The pin 22b of the limit arm 22 engages with the rail portion 11a of the lower frame 11. As shown in FIG.
As shown in FIGS. 5(a) and 5(b), the rail portion 11a of the lower frame 11 has a substantially rectangular parallelepiped box shape. The lower surface of the rail portion 11a is provided with a groove portion R, which is a space that curves and extends in the left-right direction. The groove R is opened downward and at the right end portion of the interior of the vehicle. Along the groove R, the pin 22b of the limit arm 22 is slidable. As shown in FIG. 5B, the slide portion 21a of the operation portion 21 overlaps with the right end portion of the groove portion R on the indoor side.
As shown in FIGS. 5(a) and 5(b), the slide portion 21a of the operation portion 21 is attached inside the rail portion 11a of the lower frame 11 and has a substantially rectangular shape that is oblong in front view, and the left side in plan view. It has a substantially U-shaped shape with an opening. The movement of the slide portion 21a is interlocked with the movement of the operation portion 21, and is freely movable in the horizontal direction. When the shoji 1 is in the half-openable state, leftward movement of the slide portion 21a is prohibited because the leftward movement of the operation portion 21 is blocked by the lock mechanism 3. While the sliding portion 21a is not moved leftward and overlaps the right end of the groove R on the interior side, the opening of the right end of the groove R is blocked, and the opening of the groove R is only on the bottom surface. Become. Therefore, the pin 22b of the limit arm 22 slides only along the groove R, as shown in FIGS. That is, the pin 22b of the limit arm 22 continues to engage with the rail portion 11a of the lower frame 11 in the groove portion R when the shoji 1 is opened and closed, and the limit arm 22 and the shoji 1 are always connected.

Next, the shoji 1 in a fully openable state will be described. First, the description will be made on the basis of the time when the shoji 1 is closed.
