- a first section;
a second section; and
means for coupling the second section to the first section, the coupling means comprising;
a shaft having a first portion and a second portion, the second portion being connected to the second section;
a first member, being disposed about the shaft, having a first contact surface and a second contact surface, the second contact surface being disposed opposite to the first contact surface;
a second member being connected to the first section and disposed about the first portion, thereby rotatably connecting the shaft to the first section, the second member having a third contact surface which is disposed so as to oppose the second contact surface; and
at least one ring-shaped spring, being disposed between the second contact surface and the third contact surface, for suppressing rotation of the first section, relative to the second section, about the shaft, the second contact surface and the third contact surface extending further from the shaft than the at least one ring-shaped spring.

Abstract
A hinge device comprising a shaft to be connected at one end to a first member, a bracket mounted on the shaft, for supporting a second member such that the second member rotates around said shaft, and wave washers held and compressed between said shaft and said support means. The wave washers generates a friction between said shaft and the second member when the first and second members are rotated relative to each other around said shaft, thus suppressing the rotation of the first and second members.
