  In addition, the axis of the sliding shaft portion 311 is set within a range of the finding dimension on the inner peripheral side of the frame body 10 with respect to the bisecting surface V that bisects the finding dimension MS of the hanging base frame 12. Therefore, when the face material 20 is opened around the axis of the sliding shaft portion 311, the edge 20R facing the living room on the prospective face 20 a located on the suspension base side of the face material 20 (hereinafter simply referred to as “suspension base edge”) In this case, the gap between the hanging base frame 12 and the finding surface 12a is gradually reduced. Therefore, it becomes difficult to insert a finger between the hanging frame 12 and the hanging edge 20R of the face material 20 when opening and closing the face material 20, and there is no possibility that a situation in which the finger is pinched is caused.

  On the other hand, the gap between the prospective surface 20a of the face material 20 and the prospective surface 12a of the suspension base frame 12 increases as the face material 20 is opened. However, in the above-mentioned fittings, when the face material 20 is closed, the prospective surface 21a of the panel main body 21 is at a position where the finger cannot be pinched from the prospective surface 12a of the hanging base frame 12 (in the present embodiment, the prospective surface 21 21a is only from the prospective surface 12a of the hanging frame 12 to a position at a distance B of about 15.5 mm), and a gap from the prospective surface 21a of the panel body 21 to the prospective surface 12a of the hanging frame 12 is formed by the cover portion 222. Covered. Therefore, even when the face material 20 is closed in a state where the finger is inserted between the prospective face 21a of the face material 20 and the prospective face 12a of the hanging former frame 12, there is no possibility that the finger is injured.

  In addition, in the gap A between the hanging frame 12 and the surface material 20 that appears as a space in the appearance, the light shielding piece 234 of the spacer member 23 provided on the surface material 20 abuts on the prospective surface 12a of the hanging frame 12. As a result, no light leaks between the room and the corridor, and no air is circulated between the room and the corridor.

  In the above-described embodiment, the door provided on the wall W that separates the living room from the corridor is illustrated, but the face material 20 is rotatably supported on the frame via the hinge 30. If so, it can be similarly applied to other doors and casement windows. In this case, the center of rotation of the face material 20 does not necessarily need to be along the vertical direction, and for example, the center of rotation of the face material 20 may extend in the horizontal direction.

  Further, in the above-described embodiment, the hinge 30 is provided so as to have the axis on the inner peripheral side of the frame body 10 with respect to the bisecting surface V that bisects the finding dimension MS of the hanging frame 12. As shown in FIG. 10, the present invention includes a bisecting surface V that bisects the finding dimension MS of the frame 12, and the face material 20 is within the range of the finding dimension on the inner peripheral side of the frame 12.
