A slide rail in which a sliding member is slidably guided by one of the vertical members of the window frame and the shoji, in the shoji open state holding device provided between the window frame and the shoji, for the inwardly-folding window in which the shoji falls down to the indoor side. Is provided so that the upper end of the first arm is pivotally connected to the slide member so as to be vertically slidable with respect to the vertical member and swings in the indoor and outdoor directions, and the upper end of the second arm is mounted on the other vertical member. Pivoted to swing in the indoor and outdoor directions,
The lower portions of the first and second arms are rotatably connected to each other so that the two arms are folded when the shoji is closed, and each of the arms is connected to a vertical member on which each arm is pivoted. When the rocker swings, the shoji is configured to be in the maximum open position, and the vertical member on which the second arm is pivotally mounted includes:
A latch member which can be engaged and disengaged with a locking portion provided at the lower end of the second arm and which can prevent swinging of the second arm is provided with a locking position inside a circular locus drawn by the lower end of the second arm, The second arm pivots the second arm by being provided so as to be swingable between positions outside the trajectory and locking the latch member with the locking portion of the second arm in a state where the latch member is urged in the locking direction. It is possible to hold the shoji at the middle open position that does not rotate with respect to the vertical member
When closing the sash from the maximum open position of the sash, the urging force is applied after the locking portion of the second arm pushes the pushing surface of the latch member to rotate the latch member to the outside of the circular locus due to the rotation of the second arm. As a result, the latch member returns to the locking position and locks with the locking portion of the second arm, and thereafter, the slide member pivotally attached to the upper end of the first arm slides upward in the slide rail. A device for maintaining a sliding door in a state where a window is internally deflected.
