When the opening adjuster is installed as shown above,
When the shoji is rotated in the opening direction, the guide pin moves along the guide hole, and the notch at the upper end of the cam piece that moves together with the guide pin comes into contact with the deflection member. Due to the contact, the cam piece is held in an inclined state, and the engagement between the notch and the deflection member prevents the shoji from rotating in the opening direction. Therefore, when the shoji is returned to the closing direction, the notch at the top of the cam piece comes into contact with the stopper piece below it, and due to this contact, the cam piece rotates a little in the same direction as above, and the stopper piece The notch engages with the upper corner of the. This engagement holds the shoji in an open state.

When the shoji is further rotated in the opening direction from the open state as described above, the cam piece is rotated in the same direction due to the collision with the deflection member, and the first linear guide edge comes into contact with the tip of the deflection member. The cam piece is held in such a state that the pair of notches are opposed to each other at the top and bottom.

Therefore, by rotating the shoji in the opening direction,
The cam piece passes through the deflection member, moves further upward, and the notch abuts the tip in the sliding direction on the upper deflection member.

Therefore, when the shoji is returned to the closing direction as described above, the notch at the lower end of the cam piece engages with the upper corner of the upper stopper piece, and this engagement holds the shoji in the open state. Ru.
