Abstract: A conventional horizontal axis portion is divided into two to have a triaxial structure including a vertical axis portion. Fixing these portions by a hinge main body enables stress and moment applied to each part to be reduced, resulting in realizing down-sizing of a biaxial hinge as a whole.

Abstract: A structure is provided which is capable of reliably suppressing deformation caused by deterioration of a gasket member to maintain a dustproof function and of avoiding interference with other components mounted within electronic devices including a liquid crystal display panel. When the gasket member is made flat due to its secular changes (in geometry) and is made to extend in its width direction and, as a result, its inner wall face is deformed toward a central portion of an aperture attributed to an increase in the width of the gasket member, the deformation is suppressed by making an outer wall face of a stopping rib press the inner wall face of the gasket member.

Abstract: A mobile phone is equipped with two casings coupled to each other by a two-axis hinge. When the casings are in the folded state, one casing can make a slight rotation around the hinge axis. The casings then come into contact with each other, resulting in a flaw on the casing surface. To prevent the casings from coming into contact with each other, buffer members are arranged on the casing surface. The buffer members are formed in the casing region in the vicinity of the two-axis hinge and in the casing region on the side opposite thereto.
