ABSTRACT:
It is an object of the present invention to provide an opening/closing hinge device which can be produced simple in construction and inexpensive in production by reducing the number of the parts forming part of the mobile device and to provide a mobile device small in size, reduced in cost and sufficiently reliable in the hinged members. The second member is rotated with respect to the first member toward the opening operation direction through the movable cam (150) by the urging force of the urging means (170) when the operation cam (130) is displaced in the predetermined operation direction by the external operation force. The fixed guide member (110) has inclined guide portions (115) each inclined at an advance angle in a predetermined inclination direction with respect to the surface perpendicular to the guide center axis to have the second rotation cam (140) rotated around the guide center axis in response to the displacement of the second rotation cam (140) along the guide center axis. The second rotation cam (140) being driven to rotate by the inclined guide portions (115) under a pressing force from the movable cam (150) to have its engagement state with the movable cam (150) changed and to have the urging direction of the second member by the urging means (170) changed when the operation cam (130) is operated to cause the first rotation cam (160) to be rotated from the operation starting position.
