A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, a first wheel, and a second wheel. The first wheel and the second wheel may be rotatably coupled to the first body. A lateral surface of the first wheel comes into contact with a first rolling surface of the second body in a first contact direction, and a lateral surface of the second wheel comes into contact with a second rolling surface of the second body in a second contact direction, wherein the first contact direction and the second contact direction are symmetrical to each other about a reference surface. When the second body moves relative to the first body in a first direction or in a direction opposite to the first direction, the first wheel and the second wheel roll on the first rolling surface and the second rolling surface.
