wherein each of the plurality of columns includes:

a bottom part formed flat, and

a stepped part disposed at an upper end and a lower end of the bottom part, and

wherein the stepped part is configured to be stepped to be higher than the bottom part.

13. The portable electronic device of claim 12 , wherein the bottom parts of the plurality of columns form flat surfaces by closely contacting the surfaces of adjacent bottom parts while the first surface of the first housing and the third surface of the second housing are disposed in a same direction.

14. The portable electronic device of claim 12 , wherein the bottom parts of the plurality of columns form curved portions through by closely contacting the surfaces of adjacent bottom parts while the second surface of the first housing and the fourth surface of the second housing are disposed in a same direction.

15. The portable electronic device of claim 12 , wherein the stepped parts of the plurality of columns form flat surfaces by closely contacting the surfaces of adjacent stepped parts while the first surface of the first housing and the third surface of the second housing are disposed in a same direction.

16. The portable electronic device of claim 12 , wherein the stepped parts of the plurality of columns form curved portions by forming an aperture from the adjacent stepped parts while the second surface of the first housing and the fourth surface of the second housing face each other.

17. The portable electronic device of claim 12 ,

wherein at least some of the plurality of columns form curved portions by contacting the adjacent columns while forming a specific angle within a range of an acute angle formed by the second surface of the first housing and the fourth surface of the second housing, and
