1. A portable information device, comprising:
a first chassis having one edge portion;
a second chassis having one edge portion adjacent to the one edge portion of the first chassis;
a hinge device rotatably connecting the one edge portions of the first chassis and the second chassis;
a display seamlessly covering the first chassis and the second chassis and is foldable; and
a cover member covering a side of the hinge device,
wherein the hinge device connects the first chassis and the second chassis so as to be foldable from a usage form, in which a top surface of the first chassis and a top surface of the second chassis are on substantially the same plane, to a storage form in which the top surfaces of the first chassis and the second chassis face each other,
wherein the cover member is contained inside the first chassis and the second chassis in the usage form and covers a side of a gap formed by separation of the one edge portions of the first chassis and the second chassis in the storage form,
wherein the cover member comprises:
an attaching part attached to the hinge device; and
a cover plate part in a side of the hinge device, and
in the storage form, a tip surface is near a bending part of the display and extends beyond the bending part in a direction towards opposite edges of the display,
wherein the hinge device comprises:
a first base plate fixed to the first chassis;
a second base plate fixed to the second chassis;
a first link arm having a first end portion rotatably connected to the first base plate through a first shaft;
a second link arm having a first end portion rotatably connected to the second base plate through a second shaft; and
a coupling plate having a first end portion rotatably connected to a second end portion of the first link arm through a third shaft, and a second end portion rotatably connected to a second end portion of the second link arm through a fourth shaft,
wherein the attaching part of the cover member is attached to the coupling plate, and the cover plate part is disposed lateral to the first base plate, the second base plate, the first link arm, the second link arm, and the coupling plate.
