Abstract
A hinge device having a first installation frame () installed on a first housing (); a second installation frame () installed on a second housing (); a third installation frame () for rotatably supporting a base end section of each of the frames, the base end sections being supported such that a head section side of each frame is rotatable in a direction to approach to and separate from each other, the base end sections being supported through a first main shaft () and a second main shaft () that are arranged parallel to each other and to which rotation of the frames is transmitted; a rotation force transmission mechanism () disposed between the main shafts () and including gears () having a function of transmitting reverse rotation force from one to the other and vice versa; and a rotation angle restriction means (). The hinge device enables stable closing operation in which displacement between the housings does not occur.
