Abstract:
An opening and closing unit which satisfies required functions of an opening and closing unit and is able to more smoothly bend/unfold a terminal, link parts are slidable with rotation relative to an attaching member. Link parts are slidable with rotation relative to an attaching member. Central parts are provided between the link members and the link parts, with one end portion thereof being slidable relative to the link members with rotation, and other end portion thereof being slidable relative to the link parts with rotation. The friction generating portions are provided between an attaching part and central parts, and apply a resistance force against a rotation of the central members relative to the attaching part. The friction generating portions are provided between an attaching part and central parts, and apply a resistance force against a rotation of the central parts relative to the attaching part.
