Had a structure in which the upper hinge 3 and the lower hinge 4 were combined on one side above and below. However, in the region where the door body 2, the upper hinge 3 and the lower hinge 4 overlap, the upper hinge 3 and the lower hinge 4 affect the high frequency impedance of the door body 2 and deteriorate the high frequency leakage performance. By providing the step on the lower hinge 4, the distance from the outer wall of the door body 2 is increased as much as possible, and the influence of the upper hinge 3 and the lower hinge 4 is minimized. In addition, as shown in the sectional view of FIG.
Since the high-frequency traveling direction is different by 90 ° in the corner part, the means for adding the radio wave absorbers ferrite 6-1 and 6-2 was usually used to improve the high-frequency leakage prevention performance.
