BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-sway device for fittings such as sliding doors, and more particularly, to a sliding door standing between a lower sill groove and an upper ditch groove mainly made of wood of a building structure. In particular, the present invention relates to a steadying device for preventing rattling of a ditch at the upper end of sliding doors or the like.

[0002]

2. Description of the Related Art In general, as fittings such as sliding doors standing between a sill groove and a Kamoi groove mainly made of wood in a building structure, sliding doors, sliding doors, and sliding doors of various types such as sliding doors and sliding doors are used. (Hereinafter referred to collectively as "sliding doors"). These sliding doors, on the other hand, have a sliding door main body against a sill groove cut into the upper surface of the lower sill. The lower end surface of the sliding door is slidably fitted and supported, and on the other hand, the upper end portion of the sliding door body is loosely mounted and held so as to be able to be guided in a ditch groove cut out on the lower surface of the upper duck gate. The sliding door body is used in such a manner that the lower end surface is slid on the sill groove with the upper end part being guided in the ditch groove so that the sliding door body can be opened and closed.

[0003] However, in the case of sliding doors or the like which are used standing between a sill groove and a sluice groove of this kind, usually, the width of the groove of the sill groove is smaller than that of the lower end surface of the sliding door body. The corresponding width (thickness of the body) is matched as much as possible, but the groove width of the Kamoi groove is somewhat different from the corresponding width of the upper end of the sliding door body (similarly, the thickness of the body). That clearance is given. That is, the provision of the clearance according to the required value on the side of the Kamoi groove is such that when the sliding door body is set up, firstly, the upper end of the sliding door body is temporarily moved upward from the lower side with respect to the Kamoi groove. The sliding door body is then required to be inserted in such a way that the sliding door body is straightened in the original vertical direction, and then the lower end surface thereof is required to be fitted into the threshold groove. The groove has a groove width and a groove depth including a clearance sufficient for the upright operation of the sliding door body, and the value of the clearance increases mainly in proportion to the thickness of the sliding door body. Will be.

It is inevitable to set and provide a clearance for the value, and as a result, the sliding door body itself that has been set up can be relatively finely fitted only if it is on the lower threshold groove side. In the upper ditch groove side, undesired rattling occurs between the ditch groove and the upper end of the sliding door body due to the clearance required for the fitting, and in this case, so-called standing There is an inconvenience of getting worse. Also, the width of the upper ditch groove may be more than necessary with respect to the width of the upper end portion of the sliding door body fitted into the ditch groove. Therefore, the upper end portion of the sliding door body fitted into the ditch groove may be used. However, the sliding door body is greatly inclined in the width direction, and there is a disadvantage that the standing is extremely deteriorated as described above.

[0005] Such poor standing of the sliding doors and the like not only impairs the stability of the sliding door body and impedes the smoothness of the opening / closing operation, but also promotes the wear of the sliding portion during the opening / closing operation. In addition, there are circumstances such as allowing more intrusion of draft, and furthermore, it is not possible to avoid rattling due to changes in wind pressure or rattling due to vibration transmitted through the foundation ground, etc. For example, in the event of a typhoon or the like, there is a problem that the sliding door itself comes off from between the threshold groove and the Kamoi groove due to wind pressure.
