In order to obtain a sufficient cushioning effect, the thickness of the housing 51 must be increased.
Further, in order to protect the corner 52, the thickness of the cushioning member 55 must be increased. If the thickness of the housing 51 is increased in order to satisfy these requirements, a problem arises in that the internal space of the housing 52 is narrowed. In addition, when the thickness of the buffer member 55 is increased, the amount of protrusion of the buffer member 55 from the housing 51 increases, and the buffer member 55 itself becomes large, resulting in poor appearance.

In particular, housings used for electronic devices and the like have been reduced in size and portability, and high-performance housings have been increasing. Therefore, in order to reduce the size and weight of the housing 52 and to make effective use of the internal space, it is desired that the housing 51 be thin and strong. At the same time, it is desired to have an impact resistance at the time of carrying. To cope with this, improvements in materials mainly used for the housing 52 are currently in progress.
In addition, a structure in which the housing 52 itself can increase rigidity is desired.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and can improve the impact resistance of a corner even if the thickness of the housing is thin, and can reduce the amount of protrusion of the cushioning member at the corner. It is intended to provide a protective structure for a housing.

The corner portion A (the joint portion between the side plates 3a and 3b) will be described as an example. In this corner portion A, a predetermined angle (90 in the illustrated example) is set with respect to the joint angle (for example, 90 degrees) between the side plate 3a and the side plate 3b. Two bent pieces 3e and 3f that are bent each time are formed continuously.

By the bent pieces 3e and 3f, a predetermined amount of the concave portion 3AA is formed on the outer surface of the corner A of the housing 1. Similar bent pieces are also formed in other corners B to D. Accordingly, the length of each of the side plates 3a to 3d (for example, the length L1 of the side plate 3a and the length L2 of the side plate 3b) is formed to be shorter than before providing the bent pieces 3e and 3f, respectively.

A cushioning member 8 is provided at each of the corners A to D. The buffer member 8 is formed using a urethane resin such as urethane rubber as an elastic material. Explaining the cushioning member 8 at the corner A, the side plates 3a, 3b
Are formed in a substantially L-shape having pieces 8a and 8b respectively covering a part of. In addition, a concave portion 3AA is provided inside the joint portion of the pieces 8a and 8b corresponding to the concave portion 3AA.
A protrusion 8c having a shape corresponding to the dent is formed to protrude. Note that the cushioning member 8 may have a back piece 8d extended at the corner A so as to cover the back side of the back plate 2.
