ンジが提案されている。2. Description of the Related Art Portable so-called OA (office automation) devices such as personal computers (personal computers), word processors, printers and the like are often provided with a foldable lid because of their portability. For example, a laptop computer has a keyboard etc. arranged on the front side, and on the other side, a lid with a display screen is attached via a hinge, and the lid is rotated a half turn so that the display screen faces the operating side. ing. Although the display screen is viewed from the front side of the operation side, it is desirable that the lid part be stopped at an arbitrary position due to the rotational movement of the display screen from the viewpoint of usability such that ambient light is reflected on the glass plate on the surface and becomes difficult to see .. In view of such a situation, a hinge with a torque function has been proposed in which a rotating torque function is added to the hinge so that the display screen can be stopped at an arbitrary position.
