Abstract
A reservoir cap includes a cylinder portion of molded resin and surrounding an outer circumferential surface of an opening portion of a reservoir body, and a flat portion unitarily formed on the cylinder portion and closing the opening portion of the reservoir body. A transparent film is insert-molded to the outer surface of the flat portion. Descriptive characters are formed at an inner surface of the film. The film is made from the same material as the flat portion. It is therefore possible to obtain a high adhesion between the film and the flat portion of the reservoir cap because they have the same melting point. Therefore, it is possible to provide an improved reservoir cap having descriptive characters which are easily seen from the outside thereof at the flat portion, while ensuring a high chemical resistance and a high durability against the operational fluid. Furthermore, it is possible to improve the appearance of the reservoir cap while ensuring the high chemical resistance and the high durability against the operational fluid.
