ABSTRACT:
A hinge structure by which an upper unit of a housing can open and close with respect to its lower unit around its edge includes two elastic bars twisting around each other. The elastic forces of these bars are set according to the shearing stress applied to them. Contact pieces may be provided to vary their elastic forces when the units are assembled together. Screws may be further provided to vary the twisting angles of the bars to adjust their elastic forces.
