Abstract
This specification discloses a molded article, for example an original document cover plate for use in a copier, composed of a flexible hinge portion and a pair of solid portions faced across the hinge portion, and adapted to be folded at the hinge portion. The hinge portion has a structure to avoid stress concentration on the end areas in the width direction of the hinge portion.
