1. A portable communication device comprising:
a housing including a first housing portion and a second housing portion;
a flexible display disposed over the first housing portion and the second housing portion; and
a hinge structure disposed substantially between the first housing portion and the second housing portion,
wherein the hinge structure includes:
a first shaft configured to rotate about a first axis;
a second shaft configured to rotate about a second axis parallel to the first axis;
a first cam structure configured to move in a length direction of the first shaft as the first shaft is rotated about the first axis;
a second cam structure configured to move in the length direction of the first shaft as the first shaft is rotated about the first axis;
a third cam structure configured to move in a length direction of the second shaft as the second shaft is rotated about the second axis; and
a fourth cam structure configured to move in the length direction of the second shaft as the second shaft is rotated about the second axis;
a first elastic member disposed between the first cam structure and the second cam structure; and
a second elastic member disposed between the third cam structure and the fourth cam structure;
wherein at least part of the first cam structure and at least part of the third cam structure are configured to move in a first direction of the length direction according to folding of the housing such that the first elastic member and the second elastic member are compressed at least by the first cam structure and the third cam structure, respectively; and
wherein, temporarily while the at least part of the first cam structure and the at least part of the third cam structure move in the first direction, at least part of the second cam structure and at least part of the fourth cam structure are configured to move in a second direction opposite to the first direction such that the first elastic member and the second elastic member are partially uncompressed by the second cam structure and the fourth cam structure, respectively.
