摘要： A valve rocker cover is securely mounted on a cylinder head of an internal combustion engine. The valve rocker cover includes a rocker cover main body made of a plastic and of a generally upturned vessel shape so as to be opened at its bottom end. The main body includes a roof section which is formed with a plurality of openings through which metal pipe members extending from the cylinder head are respectively disposed. A plurality of annular oil seal members are disposed coaxial respectively with the openings and made of an elastomeric material. The annular inward lip section of each seal member is in contact with the metal pipe member. A plurality of annular support members for the oil seal members are disposed coaxial respectively with the openings and made of a plastic. The annular outward section of the oil seal member is fixedly secured to the inner peripheral portion of each annular support member. The rocker cover main body is formed with a surface facing downward, forming part of the rocker cover main body. Each annular support member is welded at its top surface to the downward facing surface of the rocker cover main body.
