<p>A hinge device has a case (10), a coil spring (60), a sliding disk (20), and a rotating disk (30). The case (10) has a positioning recess (13) in its inner wall. The sliding disk (20) has on its peripheral surface a projection (24) that engages with the positioning recess (13) of the case (10) to restrain the rotation of the case (10). One end surface of the sliding disk (20) and one end surface of the rotating disk (30) are butted against each other, and cams (23, 33) that are engaged with and disengaged from each other as the rotating disk (30) rotates are formed at the butting end surfaces. The cam (23) formed on the sliding disk (20) projects radially outward from the outer peripheral surface of the sliding disk (20).</p> |
