1. An electronic device comprising:
a housing including a first housing and a second housing;
a display extending from the first housing to the second housing; and
a hinge structure comprising a hinge connected to the first housing and the second housing,
wherein the hinge structure includes:
a fixed portion;
a first rotary portion coupled to the fixed structure to be rotatable about a first axis of rotation and connected to the first housing;
a second rotary portion coupled to the fixed structure to be rotatable about a second axis of rotation and connected to the second housing, wherein the first axis of rotation and the second axis of rotation extend parallel to an axial direction;
a first arm shaft rotatably coupled to the fixed portion and parallel to the axial direction;
a second arm shaft rotatably coupled to the fixed portion and parallel to the axial direction;
a first arm coupled to the first arm shaft configured to rotate together with the first arm shaft, the first arm including a first arm cam formed around the first arm shaft;
a second arm coupled to the second arm shaft configured to rotate together with the second arm shaft, the second arm including a second arm cam formed around the second arm shaft;
a first elastic member coupled to the first arm shaft and configured to apply an elastic force in the axial direction;
a second elastic member coupled to the second arm shaft and configured to apply an elastic force in the axial direction;
a first moving cam coupled to the first arm shaft configured to linearly move in the axial direction and rotate about the axial direction, the first moving cam being supported by the first elastic member and located between the first elastic member and the first arm cam;
a second moving cam coupled to the second arm shaft configured to linearly move in the axial direction and rotate about the axial direction, the second moving cam being supported by the second elastic member and located between the second elastic member and the second arm cam; and
a cam coupled to the first arm shaft and the second arm shaft configured to linearly move in the axial direction, and
wherein the cam includes:
a first portion through which the first arm shaft passes, the first portion including a first cam engaged with the first arm cam and a second cam engaged with the first moving cam;
a second portion through which the second arm shaft passes, the second portion including a third cam engaged with the second arm cam and a fourth cam engaged with the second moving cam; and
a connecting portion connecting the first portion and the second portion.
