摘要

The rear housing composing the display portion includes a raised portion and a non-raised portion with a level difference therebetween. The rear housing of the display portion is formed in such a manner that the non-raised portion has a cylindrically curved surface and that the level difference has an edge line at right angles with the lateral line of the cylindrically curved surface. The rear housing has such an automobile hood structure with a partially raised surface, thereby being prevented from being deformed due to external pressure not only in its width direction but also in its longitudinal direction.
