International Publication No. 2017/11473

The opening and closing force applied to the user when opening and closing the shoji varies depending on the diameter of the door roller. Generally, the larger the diameter of the door roller, the smaller the opening / closing force, and the user can easily open / close the shoji. Further, as the diameter of the door roller increases, the number of rotations of the door roller per unit distance decreases, so that the durability of the door roller increases. However, if the size of the frame is constant, the larger the diameter of the door roller, the smaller the glass plate, the higher the height of the door roller cover and the lower stile, and the lower the viewability and heat insulation of the shoji.

The present disclosure provides a door roller device, a shoji screen, and a fitting that do not excessively increase the opening / closing force and easily maintain the durability of the door roller, the viewability of the shoji screen, and the heat insulating property.

The door roller device according to the present disclosure includes a door roller case configured to be installable on the lower frame of the shoji frame, and a rail portion of the lower frame of the frame body which is housed and supported in the door roller case and in which the shoji is housed. The door roller is rotatably provided, and the upper end portion protrudes from the upper surface of the door roller case.
