The upper lateral edge 521 of the frame-side blade portion 52 in the hinge device 4C is inclined with respect to the direction orthogonal to the axial direction of the connecting shaft portion 8 (the Z-axis direction in FIG. 6), and the longitudinal edge 523 of the upper lateral edge 521 The end on the side is located below the end on the longitudinal edge 524 side. In addition, the lower lateral edge 622 of the door-side blade portion 62 in the hinge device 4C is inclined with respect to the direction orthogonal to the axial direction of the connecting shaft portion 8 (the Z-axis direction in FIG. 6), and the lower lateral edge 622 The end on the side of the longitudinal edge 623 is located above the end on the side of the longitudinal edge 624. like Therefore, since the upper lateral edge 521 and the lower lateral edge 622 are inclined, as shown in FIG. The interval between the side blade portions 62 gradually expands from the side of the connecting shaft portion 8 toward the side of the longitudinal edges 523 and 623. Here, the first lateral edge portions 625 and 625 are separated by the upper lateral edge 521 and the lower lateral edge 622, respectively, by a size that is greater than or equal to the finger width dimension W1. The regional composition. In addition, the second lateral edge portions 626 and 626 are respectively constituted by an area between the upper lateral edge 521 and the lower lateral edge 622 of the upper lateral edge 521 and the lower lateral edge 622, which is smaller than the finger width dimension W1. In addition, in the hinge device 4C, the first lateral edge portion 625 and the second lateral edge portion 626 are not continuous with each other by the continuous edge portion 627 described above.

In this hinge device 4C, the following structure is also adopted. That is, since the finger avoiding space 10 is formed between the first lateral edge portions 625 and 625, on the other hand, the second lateral edge portions 626 and 626 are narrowed. Therefore, it is difficult to insert the finger 9 from the outdoor side.

In the second modification as described above, both the upper lateral edge 521 of the frame side blade portion 52 and the lower lateral edge 622 of the door side blade portion 62 have a first lateral edge portion 625 and a second lateral edge portion 626, But it is not limited to this. For example, it may be that only one of the upper lateral edge 521 and the lower lateral edge 622 has a first lateral edge portion 625 and a second lateral edge portion 626, and the other lateral edge runs along the connecting shaft portion 8. The axial direction is perpendicular to the direction of the formation. At this time, the inclination angle of the one lateral edge with respect to the direction orthogonal to the axial direction of the connecting shaft portion 8 (the Z-axis direction in FIG. 6) is set to be greater than the upper lateral edge 521 and the lower lateral edge 622 Both have a first lateral edge portion 625 In the case of the second lateral edge portion 626, the inclination angles of the upper lateral edge 521 and the lower lateral edge 622 are large.
