Claims (1)

[Scope of Claim for Utility Model Registration] 1. On the upper and lower sides of two sliding door bodies whose abutting sides are formed by bending the peripheral edges of flat thin steel plates into a planar wedge shape, near both ends in the width direction of the back surface of each sliding door. Attach the bracket member that supports the vertically oriented shaft,
A bearing member that can change its position vertically with respect to the bracket member with screws is attached to this bracket member, and a wheel mounting shaft having a wheel with a flange at the lower end is rotatable and vertically slidable on this bearing member. On the other hand, the upper and lower stile to which both the sliding doors are attached are provided with rails having a concave cross-section, which are formed along the trajectory that the sliding door wants to draw when opening and closing, and into which the flanges of the wheels are fitted and guided. 1. A flat sliding door device characterized in that the sliding door device is formed separately into a central portion, a linear portion, and an outer end block, and these rail blocks are connected. 2. The flat sliding door device according to claim 1, wherein the wheel mounting shaft on the upper stile side of the sliding door is constantly subjected to a pushing force toward the upper stile side by a spring. 3. The rails in the central rail block are flat rails according to claim 1 or 2 of the utility model registration claim, in which a curvature is applied to the straight rail section continuous with the oblique rail section on which the flanged wheel runs obliquely. Sliding door device. 4. The flat sliding door device according to claim 1 or 2, wherein the left and right wheel mounting shafts of one sliding door are connected by a tie rod member. 5. The rail in the central rail block is a part of the rail where the flanged wheel runs diagonally as a movable rail that is opened and closed by the repulsive force of a spring. flat sliding door device. 6. A flat sliding door device according to any one of claims 1 to 5 of the utility model registration claim, in which the upper and lower stiles are connected on both sides by frame members.
