HINGE AND FOLDABLE ELECTRONIC DEVICE INCLUDING SAME

Disclosed is a foldable electronic device including a hinge. A foldable electronic device according to various embodiments of the disclosure may include a foldable enclosure which includes multiple sub-enclosures and is folded and unfolded, a hinge configured to rotatably connect the multiple sub-enclosures around at least one rotation axis, wherein the hinge may include multiple hinge leaves respectively coupled to ends of the multiple sub-enclosures and configured to rotate during folding and unfolding operations of the foldable enclosure, a rotation guide which is formed on each of the hinge leaves and includes a rotation surface having a curved-surface of a shape corresponding to a rotation trajectory of the hinge leaves, a force transmission member having a pressing surface pressed against the rotation surface of the rotation guide, a force diverting part configured to change the direction of a force applied in a direction having a directional component parallel to the pressing surface to a direction having a directional component perpendicular to the pressing surface, so as to press the force transmission member against the curved-surface of the rotation guide, and a hinge actuator configured to apply a force to the force diverting part in a direction having a directional component parallel to the pressing surface.
