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.
