Claim 19:
20. An electronic device comprising:
a housing comprising a first housing and a second housing;
a display configured to extend from the first housing to the second housing; and
a hinge structure configured to rotatably connect the first housing and the second housing,
wherein the hinge structure comprises:
a fixed member,
a first rotary member coupled to the fixed member so as to be rotatable about a first axis of rotation parallel to an axial direction and connected with the first housing, the first rotary member comprising a first guide protrusion,
a second rotary member coupled to the fixed member so as to be rotatable about a second axis of rotation parallel to the axial direction and connected with the second housing, the second rotary member comprising a second guide protrusion,
a first arm shaft rotatably coupled to the fixed member and parallel to the axial direction,
a second arm shaft rotatably coupled to the fixed member and parallel to the axial direction,
a first arm coupled to the first arm shaft and configured to rotate together with the first arm shaft, the first arm comprising a first cam configured to surround the first arm shaft,
a second arm coupled to the second arm shaft and configured to rotate together with the second arm shaft, the second arm comprising a second cam configured to surround the second arm shaft,
a cam member coupled to the first arm shaft and the second arm shaft and linearly movable in the axial direction, the cam member comprising a third cam engaged with the first cam and a fourth cam engaged with the second cam,
a first elastic member coupled to the first arm shaft and configured to provide an elastic force to the cam member in the axial direction,
a second elastic member coupled to the second arm shaft and configured to provide an elastic force to the cam member in the axial direction,
a first guide member coupled to the first rotary member so as to be rotatable about a third axis of rotation parallel to the first axis of rotation, the first guide member a first guide groove having an arc shape in which the first guide protrusion is accommodated, and the third axis of rotation being defined as a center of the arc of the first guide groove,
a second guide member coupled to the second rotary member so as to be rotatable about a fourth axis of rotation parallel to the second axis of rotation, the second guide member comprising a second guide groove having an arc shape in which the second guide protrusion is accommodated, and the fourth axis of rotation being defined as a center of the arc of the second guide groove,
a first rotary plate coupled to the first guide member to rotate together with the first guide member and configured to support a partial area of the display, and
a second rotary plate coupled to the second guide member to rotate together with the second guide member and configured to support another partial area of the display,

wherein the first guide member and the second guide member are configured to rotate relative to the first rotary member and the second rotary member as the first rotary member and the second rotary member rotate, and
wherein when viewed in the axial direction, each of the third axis of rotation and the fourth axis of rotation overlaps at least a partial area of the display.
