CYLINDER HEAD COVER FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a cylinder head cover lightened in its entirety by reducing and thinning the sectional shape of a flange part attendant on the opening end edge of a cylinder head cover.SOLUTION: The sectional shape containing the width dimension W1 of a flange part 3 of an open end edge forming a cover part 2 and a cylinder head cover 1 is reduced, and the thickness t2 thereof is thinned to a level as thin as the thickness t1 of the cover part 2. Considering the formability of the cylinder head cover 1, a thick bead part 12 is formed along the longitudinal direction of the cover part 2 so that the fluidity of the resin material in a molten state may not be deteriorated as the cover part 2 and the like are thinned. The thick bead part 12 is bulged toward the inner face side of the cover part 2.
