However, in the conventional folding cellular phone, for example, when the first casing and the second casing are opened and accidentally dropped on the floor surface, a large impact in the opening direction is applied to the first and second casings. When a force is applied and a spreading force exceeding an allowable limit is applied to the first housing, the cover member bends, thereby disengaging from the first housing, and the cover member is removed from the first housing. I sometimes left.
In order to solve this problem, the cover member may be screwed to the first housing, but in this case, the assembly becomes complicated.
SUMMARY OF THE INVENTION An object of the present invention is to provide a portable electronic device that is easy to assemble and that does not cause the cover member to be detached from the housing even by the action of a large impact force.

In the portable electronic device according to the present invention, a pair of casings (1) and (2) are connected to each other via a metal hinge frame (50) so as to be opened and closed, and the pair of casings (1) and (2). One of the housings is provided with an opening (15) through which the hinge frame (50) is exposed, and a cover member (7) is attached to the one housing to the opening (15). (15) is blocked.
Between the hinge frame (50) and the cover member (7), there is at least one connecting piece (8) that engages with the hinge frame (50) and the cover member (7), respectively. (8) and the engaging part between the hinge frame (50) and the engaging part between the connecting piece (8) and the cover member (7), respectively, in the direction in which the cover member (7) is detached from the casing. A receiving structure for receiving the acting force is formed.

  In the portable electronic device according to the present invention, when a large impact force is applied to the cover member (7) in a direction in which the cover member (7) is detached from the housing due to, for example, dropping, the impact force is applied to the cover member. It is received by the receiving structure formed at the engaging portion between (7) and the connecting piece (8), and transmitted to the connecting piece (8) through the receiving structure. Further, the impact force is received by the receiving structure formed in the engaging portion between the connecting piece (8) and the hinge frame (50) and transmitted to the hinge frame (50) through the receiving structure. Become. Since the hinge frame (50) is made of metal and has high rigidity, the hinge frame (50) exhibits a large resistance against the impact force. Therefore, the cover member (7) and the connecting piece (8) are not detached from the hinge frame (50). For this reason, it is not necessary to screw the cover member (7) to the housing, and assembly is easy.
