供することを目的としている。The above-mentioned conventional friction hinge is a friction hinge utilizing a slip torque between a coil spring and a rotating member which are mounted in close contact with the rotating member, but the slip torque is applied to the coil spring. If you add
The shape is deformed and broken by the maximum bending stress generated on the diameter opposite to the supporting points at both ends of the coil spring. FIG. 16 is an explanatory diagram of this state. Both ends of the coil spring 13 are pressed and deformed as shown by the dotted line, and are broken at 16 due to the maximum bending stress generated on the opposite diameter. This invention eliminates such conventional disadvantages, and provides a friction hinge that can stabilize the fluctuation of friction torque due to deformation of the coil spring end and prevent breakage to greatly improve the number of durability. It is an object.

As shown in FIG. 8, a cover member may be separately fixed to each coil spring. In FIG. 1, the rotation shaft 5 is indicated by an arrow A.
When the coil springs 1 and 2 rotate in the direction, both of the internal coil springs 1 and 2 also try to rotate in the direction of arrow A.
Rotation in the direction will be prevented. When the rotating shaft 5 further rotates in the direction of arrow A, the coils of the coil springs 1 and 2 are openable, but since the cover member 6 is in contact, the deformation of both ends of the coil spring causes the cover member 6 to deform. Even if the rotation is continued, the coil springs 1 and 2 remain at the same position without rotating, and the rotating shaft 5 and the coil springs 1 and 2 are not rotated.
And a friction is generated between them, thereby fulfilling a function as a friction hinge. When the rotating shaft 5 rotates in the direction of arrow B, the other ends of the coil springs 1 and 2 shown in the center of FIG. Performs the function of a friction hinge in the same manner as.
