It is attached so that it can rotate freely.

At this time, there is a discrepancy between the center of the longitudinal hole of the adjustment piece and the front and rear end surfaces, and since the front and rear end surfaces are provided with serrations that engage with the serrations of the rear wall of the bearing member, the sliding By changing the front-rear direction of the moving piece and adjusting the engagement position in the left-right direction between the saw-toothed portions on the front and rear end faces and the saw-toothed portions on the bearing member, manufacturing errors when assembling the opening frame of the shoji can be reduced. Errors in the longitudinal and lateral directions due to construction errors are absorbed, and adjustment work when assembling the shoji can be performed easily and accurately.

Furthermore, since the groove-shaped piece constituting the main body of the hollow bearing member attached to the shoji side has an open front end surface, the bearing member is attached to the central rod of the shaft metal so that the shoji is parallel to the opening frame. After fitting, the adjusting piece is rotated slightly to fit into the groove-shaped piece, so that the shoji can be assembled into the opening frame in a stable state during work.

Further, in the present invention, as described above, the serrated portion provided on the rear surface of the center portion of the cover engages with the serrated portion of the adjustment piece, and the left and right end locking portions are provided on both left and right sides of the groove-shaped piece in the bearing member. Since it is locked to the tip of the hollow bearing member and is closed with the hollow bearing member, when an external force such as wind pressure is applied, the grooved piece and the adjustment piece are firmly held in a predetermined position and there is no risk of displacement or deformation. There is no.

Furthermore, according to the present invention, the shaft hardware and the hollow bearing member are assembled to the opening frame and the shoji, respectively, and the adjustment piece and the decorative cover are assembled after hanging, so that the opening frame and the shoji are assembled with each other. Both shoji and shoji can be hung with the shaft hardware and hollow bearing members fixed, making the work easier.The weight of the shoji is supported by the hollow bearing member on the lower opening frame side, and the adjustment piece Since the weight of the shoji is not applied to the decorative cover, the adjustment pieces and the decorative cover can be easily removed. Therefore, according to the present invention, when adjusting the shoji in the left and right direction, the adjustment work can be done without removing the shoji. This makes the adjustment work easier.

The present invention will be described below with reference to the illustrated embodiments.
