    Conventionally, in a daylighting door used in a building, for example, as shown in FIG. 6, an opening K is provided in the daylighting door 11 as a structure of the daylighting portion, and a core S is attached to the periphery of the opening K. The vertical frame G and the horizontal frame G are attached to the core S of the door opening K from the front and back surfaces of the daylighting door, and the frame G holds the translucent member Q from the front and rear surfaces of the daylighting door. A daylighting door 11 having an attached structure has been used.

  In the daylighting door having this structure, the structure is complicated, and there is a great problem in workability when the frame is attached to the core around the periphery of the opening.

  Therefore, a window frame structure has been conventionally disclosed in which a frame joined from the front and back sides is used without using a frame, and the edge of the glass plate is directly fitted into and held in a groove provided in the peripheral surface of the frame. ing. However, it is difficult to maintain sufficient strength because the frames are simply joined from the front and back, and it is difficult from the viewpoint of workability such as joining the frames and fitting and holding the light-transmitting member in the groove. In addition, the conventional packing member is always necessary to prevent the light-transmitting member from rattling, which is not only inferior in strength and durability but also disadvantageous in cost.

  Therefore, this point is solved, a conventional frame is not required, and the surface portion and the edge portion are integrally formed so as to be a single plane, and has a aesthetic appearance with no protrusion, and is a translucent member. In order to realize a daylighting door that does not require a conventional packing and has excellent strength, an opening is provided in the daylighting door, a core material is disposed on the inner peripheral surface of the opening, and the opening is provided at the periphery of the core material. An edge part forming a peripheral surface is provided so that the opposing surfaces come into contact with each other from the front and back of the daylighting door, and the surface part and the outer surface of the edge part are integrally formed so that the outer surface of the edge part is a flat surface. A notch part is formed to form a fitting groove substantially equal to the thickness of the translucent member, the fitting groove is provided on the inner peripheral surface of the edge part by the notch part, and the outer peripheral edge of the translucent member is used as the fitting groove. There is a description of a daylighting door having a fitted configuration. (For example, refer to Patent Document 1).
