4 . The electronic device of claim 3 , wherein the metal member includes at least one of nickel, iron, manganese, molybdenum, or copper.
5 . The electronic device of claim 2 , wherein the third side includes a recess for accommodating at least a portion of the deformation member.
6 . The electronic device of claim 1 , further comprising:
a display support plate supporting at least a portion of the display and being at least partially disposed between the display and the hinge.
7 . The electronic device of claim 6 , wherein the display support plate provides an accommodation space surrounding at least a portion of the display support.
8 . The electronic device of claim 6 ,
wherein the display support plate includes a first plate surface supporting the display,
wherein the display support further comprises a first support surface located at an end portion of the second side, and
wherein the first plate surface and the first support surface are parallel to each other in the unfolded state of the electronic device.
9 . The electronic device of claim 1 , wherein the gear assembly includes a first gear and a second gear, the first gear being configured to rotate based on the rotation of the hinge, the second gear being meshed with the first gear and connected to the first side.
10 . The electronic device of claim 1 , wherein the hinge further comprises:
an interlocking structure configured to interlock rotation of the first rotation structure with the second rotation structure.
11 . The electronic device of claim 10 , wherein at least a portion of the display support is located between the first rotation axis and the second rotation axis.
12 . The electronic device of claim 10 ,
wherein the interlocking structure includes at least one interlocking gear configured to rotate according to the rotation of the first rotation structure or the second rotation structure, and
wherein the gear assembly is connected to the at least one interlocking gear.
13 . The electronic device of claim 1 , further comprising:
a hinge cover connected to the hinge,
wherein the display support is disposed between the hinge cover and the folding area.
14 . The electronic device of claim 2 ,
wherein the second side includes the first support surface facing the display in the unfolded state of the electronic device,
wherein the third side includes the second support surface facing the display and accommodating a deformation member in the folded state of the electronic device, and
