1. An electronic device housing comprising:
a case having a bottom-surface portion in a rectangular shape and side-surface portions provided so as to stand around the bottom-surface portion; and
a cover opposed to the bottom-surface portion and covering an opening enclosed by ends of a plurality of the side-surface portions, wherein
at positions along each of at least two opposing side lines of the cover, two flexible arm portions are provided so as to extend toward the bottom-surface portion along the corresponding side-surface portion, and two protrusions are provided between the two arm portions so as to protrude from the side-surface portion and are held between the two arm portions so as to contact therewith,
contact parts of either the arm portions or the protrusions have curved-surface portions, and contact parts of others have flat-surface portions,
two of the flat-surface portions provided on a side of each side line of the cover where the two arm portions are provided are inclined such that an interval between the two flat-surface portions is narrowed toward the bottom-surface portion and are closest to each other nearer to the bottom-surface portion than to portions of the cover from which the two of the flat-surface portions are protruded from the cover, and
the arm portions bend while pressing the protrusions at positions contacting with the protrusions.
