Abstract:
1. A hinge device comprising: a first hinge member; a second hinge member arranged opposite to the first hinge member; a hinge pin turnably connected to the first hinge member and non-turnably connected to the second hinge member; and a turn biasing mechanism configured to turn bias the first hinge member in a first direction with respect to the second hinge member when the first hinge member is in a predetermined biasing angle range with respect to the second hinge member, wherein the turn biasing mechanism comprises: wherein a fitting hole is formed in the first hinge member, and the hinge pin is turnably press-fitted in the fitting hole such that a frictional resistance of a predetermined force between an inner peripheral surface of the fitting hole and an outer peripheral surface of the hinge pin prevents relative rotation between the first hinge member and the hinge pin, at least when the first hinge member is outside the biasing angle range.
