A curved guide portion 71b is continuous with the other end side of the width direction guide portion 71a.

The curved guide portion 71b is a concave groove-shaped member continuous with the width direction guide portion 71a. The curved guide portion 71b is formed in a curved shape that gradually moves in the closing direction of the opening/closing member as it goes in the sliding direction (rightward direction in the drawing) accompanying the closing operation of the opening/closing member 10, and closes the tip portion thereof. . The tip portion is positioned substantially at the center in the width direction of the opening/closing body 10 (see FIG. 1).

As shown in FIG. 4, the width direction guide portion 71a and the curved guide portion 71b are formed to have a substantially C-shaped cross section, and are loosely fitted so that the slide support member 72, which will be described later, cannot come off in the thickness direction of the opening/closing body. is doing.

The slide support member 72 is a member that fits into the rail member 71 and slides in the extending direction of the rail member 71, and rotatably pivots the deflection suppressing member 80 thereon.
4, the slide support member 72 is composed of a shaft member 72a rotatably inserted into the support piece 84 and a rail member 71 at the proximal end side of the shaft member 72a. It is integrally provided with a slide piece portion 72b that engages and slides. The slide piece portion 72b is configured in, for example, a cylindrical roller shape or other slidable shape.

The bending restraint member 80 is formed in an elongated shape with one end side pivotally attached to the slide support member 72 and the other end side pivotally attached to the closing direction end side of the opening/closing body 10 .
The deflection suppressing member 80 is configured to slide along the rail member 71 of the slide support member 72 and rotate around the shaft member 72a of the slide support member 72, so that the front or back of the opening/closing body 10 in the closed state is adjusted. 1) and a storage position along the rail member 71 (see FIG. 2). Stand almost upright.

More specifically, the bending restraint member 80 consists of a base end rod 81 pivotally attached to the slide support member 72 and a base end rod 81 attached to the other end (lower end according to FIG. 1) of the base end rod 81. It comprises a slide rod 82 connected so as to slide linearly, and a cushioning member 83 that approaches or comes into contact with the front or back of the opening/closing body 10 at the deflection suppression position.

The support piece 84 is fixed to one end side of the base end side rod 81 , and is annularly and rotatably attached to the shaft-like member 72 a of the slide support member 72 .

The slide rod 82 is made of a hard material such as metal and has an elongated cylindrical shape. . The other end of the slide rod 82 is rotatably pivoted to the closing direction end of the opening/closing body 10 (specifically, the seat plate member 12) via a shaft-like member, a bracket, and the like.

The cushioning member 83 is made of an elastic material such as rubber or elastomer resin, and is disposed so as to be close to at least the approximate central portion of the opening/closing body in the closed state in the opening/closing direction and width direction.
According to a preferred example of the present embodiment, the cushioning member 83 is configured in a cylindrical shape covering the entire outer peripheral portion of the slide rod 82 and is provided over substantially the entire length of the slide rod 82 in the longitudinal direction.

Next, the characteristic functions and effects of the opening/closing device 1 configured as described above will be described in detail.
When the opening/closing body 10 is closed, the deflection suppressing member 80 slides along the rail member 71 at its base end side and rotates around the shaft-like member 72a of the slide support member 72 as a fulcrum. The range over rod 81 and slide rod 82 is extended.
Then, when the opening/closing body 10 is substantially fully closed, the deflection suppressing member 80 approaches or contacts the front or back part of the opening/closing body 10 and assumes a deflection suppression position in which it stands substantially upright.

In this deflection suppression position, when the opening/closing body 10 is exposed to the wind and a force is applied to the opening/closing body 10 to bend in the thickness direction, the central side of the opening/closing body 10 is received by the suppressing member 80. Bending of the body 10 can be suppressed.
In addition, even if the opening/closing body 10 is blown by the wind and flutters in the thickness direction and strongly or repeatedly contacts the deflection suppressing member 80, the impact caused by this contact is mitigated by the cushioning member 83. be able to.

Then, when the opening/closing body 10 is substantially fully opened, the deflection suppressing member 80 is in a storage position along the rail member 71 within the storage case 31 (see FIG. 2).

Therefore, according to the opening/closing device 1, it is possible to effectively reduce impacts, vibrations, noise, etc. caused by the bending and fluttering of the opening/closing body 10 in the closed state.
Moreover, since the direction in which the bending suppression member 80 slides is gradually changed by the curved guide portion 71b, the operability is excellent.
Moreover, in the fully closed state of the opening/closing body 10, the deflection suppressing member 80 is arranged vertically in a substantially central portion of the opening/closing body 10 in the width direction. and good external appearance.
In particular, if the opening/closing device 1 is mounted on a window sash or the like and the deflection suppressing member 80 is positioned between the opening/closing body 10 and the screen door or the vertical frame of the window, the deflection suppressing member 80 can be moved by the vertical frame. can be made inconspicuous.
