Abstract: An electronic device may include a display including a first area, a second area, and a third area between at least the first area and the second area, a first housing configured to support the first area, a second housing configured to support the second area, and a hinge assembly configured to connect the first housing to the second housing and operate between a folded state in which the first area and the second area face each other and an unfolded state in which the first area and the second area are open. The hinge assembly may include a hinge bracket, a first rotator connected to the first housing and rotatably connected to the hinge bracket based on a first hinge axis, a second rotator connected to the second housing and rotatably connected to the hinge bracket based on a second hinge axis, a slide bracket slidably connected in a first axis direction parallel with the first hinge axis or the second hinge axis by interoperating with rotations of the first rotator and the second rotator, and a detent assembly configured to provide a detent force resisting movement of the slide bracket in the first axis direction.
