Abstract
The present invention provides a cylinder head cover for an internal combustion engine having excellent vibration-damping properties which is prepared by molding a composition comprising 75 to 30% by weight, based on the composition, of resin components comprising 50 to 80% by weight of a polyamide resin and 50 to 20% by weight of a modified polyolefin resin modified with an unsaturated acid or its derivative, the total of both the resins being 100% by weight, 15 to 30% by weight of glass fibers based on the composition, and 10 to 40% by weight of mica based on the composition.
