<p>A hinge mechanism is provided to rotate or stop stably and smoothly, and to simplify the structure so as to reduce manufacturing cost. A hinge mechanism comprises a cylindrical member(5) having at least one projection(5b1) axially extended on the outer circumference thereof, a cylindrical elastic member(8) fitted in the cylindrical member to rotate and includes a slit(8b) extended axially on the outer circumference. The slit can be coupled to the projection. Rotations of the cylindrical member and cylindrical elastic member are controlled by coupling or separating the projection and slit.</p> |
