Hinge device

A hinge device for hinging a first member and a second member so that, from a face-to-face state, the second member can be turned substantially in parallel with a blocked face to expose the blocked face, said hinge device comprising

• a first base member fixed to the first member and having a first through hole,
• a second base member fixed to the second member and having a second through hole, and
• a turning shaft part engaging with the first and second through holes, said turning shaft part having a turning axis aligned with axes of said first and second through holes, and constructed so that turning the second base member with respect to the first base member rotates the turning shaft part, the turning shaft part is configured to slidingly engage the second base member and turn together with the second base member, the second base member is configured to incline relative to the turning shaft part about a swinging axis that is substantially orthogonal to the turning axis of the turning shaft part, further including an abutting part on the second base member and a sloping cam surface on the first base member, the cam surface extending around the first through hole and cooperating with the abutting part on the second base member, an elastic body disposed with one end fixed to the turning shaft part and an other end pushing the second base member so as to press the abutting part against the cam surface such that when the second base member turns with respect to the first base member, the second base member inclines relative to the turning shaft part as the abutting part slides on the cam surface.
