Electronic device including flexible display and hinge structure

An electronic device comprising:

• a first housing structure including a first surface, a second surface facing in a direction opposite to the first surface, and a first side member surrounding at least a portion of a space between the first surface and the second surface, wherein the first side member includes a first rotational support portion at an edge thereof when viewed from above the first surface;
• a second housing structure including a third surface, a fourth surface facing in a direction opposite to the third surface, and a second side member surrounding at least a portion of a space between the third surface and the fourth surface, wherein the second side member includes a second rotational support portion facing the first rotational support portion at an edge thereof when viewed from above the third surface;
• a flexible display including a first portion disposed on the first surface, a second portion disposed on the third surface, and a third portion disposed between the first portion and the second portion and having a shape variable depending on an angle between the first surface and the third surface;
• and
• a hinge structure connected to each of the first rotational support portion and the second rotational support portion, wherein the hinge structure is capable of forming a recess for accommodating at least a portion of the third portion when the angle between the first surface and the third surface is equal to or less than a predetermined first angle,
• wherein the hinge structure includes a first connecting member connected to the first rotational support portion, a second connecting member connected to the second rotational support portion, and a cover member,
• wherein a pair of hinge shafts, which extend parallel to each other, are provided by the first connecting member and the second connecting member,
• wherein the first connecting member includes a first hinge shaft, a first body surrounding a circumference of the first hinge shaft, a first protrusion protruding from one side of the first body, and a first stopper disposed on another side of the first body, and
• wherein the second connecting member includes a second hinge shaft, a second body surrounding a circumference of the second hinge shaft, a second protrusion protruding from one side of the second body, and a second stopper disposed on another side of the second body.
