<P>PROBLEM TO BE SOLVED: To avoid stress concentration on a hinge member of an opening/closing cover to decentralize stress influencing an outer shape. <P>SOLUTION: The opening/closing cover has a rib in an outer peripheral part of a tabular member, and the rib is continuously connected to a surface perpendicular to a rotation axis of the hinge member and two surfaces parallel with the rotation axis, and a surface connecting the surface perpendicular to the rotation axis of the hinge member and the rib is provided on the tabular member, and a surface connecting the surfaces parallel with the rotation axis of the hinge member and the rib is supported on the surface which is provided on the tabular member and connects the surface perpendicular to the rotation axis of the hinge member and the rib. <P>COPYRIGHT: (C)2012,JPO&INPIT |
