The hinged portion 29b may include ends connected to each other. The end of the hinged portion 29b may be connected to the second end of the elastic portion 29a. In addition, when the folding portion 22 is folded from the inner body 21, the end of the hinged portion 29b may serve as a rotation center portion of the folding portion 22. For example, when the folding portion 22 is folded from the inner body 21, a pair of hinged portions 29b may move toward each other.

[0099] The hinged connection part 29c can be provided in pairs. The first hinged connection part of a pair of hinged connection parts 29c can connect the inner body 21 to the first hinged part of a pair of hinged parts 29b. The second hinged connection part of a pair of hinged connection parts 29c can connect the folding part 22 to the second hinged part of a pair of hinged parts 29b.

The center portion of the elastic portion 29a may be a bent portion. The bent portion of the elastic portion 29a may be in contact with the bottom surface of the housing 30 and the side surface of the housing 30. Accordingly, the elastic portion 29a may absorb at least a portion of the impact applied to the corner of the housing 30.

[0102] The hinged connection portion 29 c can reduce the impact applied from the outside of the housing 30 by having a structure as described herein, and can also make the folded portion 22 and the inner body 21 contact the housing 30 by forcing the folded portion 22 and the inner body 21 toward the housing 30.

[0105] Despite Figure 6 Although not shown in the figure, based on the center line passing through the center portion of the planar shape of the first side fixing protrusion 24a, the corner of the first side fixing protrusion 24a that can be arranged on the opposite side of the first corner 24a-1 can be formed in the same manner as the second corner 24b-1. For example, each of the side fixing protrusions 24 can have the same shape and can include an instance of the first corner 24a-1 and an instance of the second corner 24b-1.

[0106] The end of the display device DPM may be engaged by the side fixing protrusion 24. For example, as described herein, the end of the display device DPM may be arranged between the first corner 24a-1 and the second corner 24b-1. The first corner 24a-1 may contact the protruding portion of the display device DPM. Accordingly, when an external impact is applied, the first corner 24a-1 may fix the display device DPM and may absorb the force applied to the point of the display device DPM.
