Claims

[Claims for Utility Model Registration] A hinge for a foldable radio telephone in which a hinge of a telephone body and a nut of a microphone piece are connected by a hinge shaft, and the microphone piece is rotatable with respect to the telephone body. In the structure, the knuckle is supported by a knuckle end face on the side of the microphone piece that supports the hinge shaft, rotates together with the microphone piece, and is separated by a rotation angle between a closed position and an open position of the microphone piece. a wear-resistant hinge plate having recesses formed at two positions on a plane; a spring supported by the hinge of the telephone body supporting the hinge shaft and biased in a direction protruding from an end surface of the hinge; , which is pressed by this spring and comes into contact with the hinge plate surface, and moves on the plane of the hinge plate by rotation of the microphone piece, and the corresponding recess in the closed position and open position of the microphone piece. A hinge structure for a foldable radiotelephone, comprising: a wear-resistant ball housed in;
