PROBLEM TO BE SOLVED: To provide a hinge structure capable of absorbing rotating force over a prescribed rotation position to prevent a member positioned at the prescribed rotation position from being damaged. SOLUTION: In this hinge structure, a guide member 25, a movable cam 27 to rotate with the guide member 25, and a coil spring 30 are provided between a first fixed cam 21 and a second fixed cam 24. In the first fixed cam 21, a first cam surface K1 is formed, and in the movable cam 27, a fourth cam surface K4 is formed. In the second fixed cam 24, a second cam surface K2 is formed, and in the guide member 25, a third cam surface K3 is formed. By means of the first and the fourth cam surfaces K1 and K4, a first rotation position is held, and area from the first rotation position to a third position opened over a second rotation position is also held. By means of the second and the third cam surfaces K2 and K3, the second rotation position is held. COPYRIGHT: (C)2005,JPO&NCIPI
