Abstract: An hinge module configured to pivotably couple first and second housings, includes a hinge bracket, a first rotation member coupled with the first housing and disposed on the hinge bracket pivotably or rotatably around a first folding axis, a second rotation member coupled with the second housing and disposed on the hinge bracket pivotably or rotatably around a second folding axis, a cam member on the hinge bracket to be linearly movable, and an elastic member providing elastic force to the cam member in a direction in which the first rotation member and the second rotation member are brought into close contact. The cam member is configured to press at least part of the first rotation member in a direction crossing the first folding axis or at least part of the second rotation member in a direction crossing the second folding axis based on elastic force of the elastic member.

Abstract: An electronic device includes a display, and a hinge assembly foldable together with the display and corresponding to a folding area of the display. The hinge assembly includes a hinge bracket defining first and second hinge axes, first and second rotators connected to the hinge bracket and respectively rotatable about the first and second hinge axes, first and second sliders connected to the hinge bracket, respectively slidable relative to the hinge bracket in a direction parallel with the hinge axes, and spaced apart from each other in the direction, and an elastic member between the first and second sliders and providing an elastic force in the direction. The first and second rotators respectively include first and second helical structures having a helical shape with the first and second hinge axes as a center, and are each connected to the first and second sliders through the first and second helical structures.
