A camera body includes a plastic body formed by molding and having a central portion with film loading and windup chambers at its opposite ends. A reinforcing metal bracket or plate is positioned in and forms a part of the central portion, the plate having at least one connecting portion which interengages the molded plastic body. The plate has a thickness substantially equal to that of the central body portion, and its connecting portions have projections for contacting a molding surface in the mold used to form the camera body in response to molding pressure applied to the projections. The projections prevent seepage of molten plastic between the plate and the molding surface, thereby preventing plastic flash from appearing at the connecting portion of the plate with the plastic body.
