Furthermore, in the illustrated embodiment, the movable blade (4)
A plate-shaped or linear spring means (5) such as a leaf spring or a wire spring (including a coiled one) is fixed to the hinged door (3) on the back surface of the hinged door (3) with which the tip of the door abuts. The plate-like or linear spring means (5) is a concept including both a plate-like or linear spring itself and a plate material or a wire material subjected to a force by the elastic means. Illustrated plate or linear spring means (5)
Is interposed between the door-side fixed body (7a) of the hinge (7) and the rear surface of the hinged door (3), and is considered to be fixed to the rear surface of the hinged door (3) at the same time when the hinge (7) is fixed. . In the illustrated embodiment, at the door-side fixed body (7a) of the hinge (7), a screw hole is provided at least on the free end side of the hinged door (3). Next, the plate-like or linear spring means (5) is shown as being cantilevered and projected from the door-side fixed body (7a) in a free state. Therefore, the tip of the movable blade (4) elastically contacts the plate-shaped or linear spring means (5) shown in the figure. Therefore, when the movable wing (4) returns, the plate-shaped or linear spring means (5) decelerates it and the movable wing (4) collides with the back surface of the hinged door (3), which may cause noise. Is prevented by.

The plate-like or linear spring means (5) is usually provided for each hinge (7), but when three or more hinges (7) are used, there may be no hinge (7). . Although the plate-shaped or linear spring means (5) is fixed together with the hinge (7), only the plate-shaped or linear spring means (5) may be separately fixed by screws or the like. Since the plate-shaped or linear spring means (5) can be thin, thin or small in volume, it is possible to prevent the movable blade (4) from being lifted up from the rear surface when the hinged door (3) is closed. To When a leaf spring (one or more, one using a perforated plate for adjusting the force, etc.) is used as the plate-like or linear spring means (5), the tip of the leaf spring is fixed to the movable blade (4). You may fold it slightly downward or fold it in the opposite direction so that it will not get caught. The reason why the door-side fixed body (7a) of the hinge (7) is provided with a screw hole at least on the free end side of the hinged door (3) is only for fixing the plate-shaped or linear spring means (5). is not. It is desirable that the hole for the screw on the free end side is located at that position also in order to support the force by pulling from the direction of the force applied to the door-side fixed body (7a) of the hinge (7). Not necessarily required. .
