Claims

[Scope of utility model registration request]

A pair of front and rear suspension roller units movably engaged with the suspension guide rail are attached to the tops of both front and rear ends of the folding door, which is made up of two door bodies connected by a hinge so that they can be folded and expanded, and each can rotate around a vertical axis. A pair of front and rear steady rest roller units, which fit into the guide rails at the bottom of the folding door, are rotatably supported at the bottom of both front and rear ends of the folding door, and are rotatably supported around a vertical axis concentric with the vertical axis. In the folding door device, each of the roller units is provided with a pair of front and rear vertical shaft rollers for steadying in addition to the supporting horizontal shaft roller, and each of the guide rails is provided with a pair of front and rear swinging shaft rollers. Each of the vertical shaft rollers for steady rest is provided with one guide groove into which the vertical shaft rollers for steady rest fit, and of the pair of vertical shaft rollers for steady rest, only the vertical shaft roller for steady rest on the side closer to the vertical shaft that pivotally supports the roller unit is provided. A folding door device that is pivotally supported via a bearing.
