ABSTRACT:
In a primary molding step, a connector housing having a hood portion is molded. In a secondary molding step, an elastic seal ring is molded on an inner side of the hood portion. Through holes are formed in the connector housing in the primary molding step which allow an elastic material to flow therethrough from a seal ring-forming portion on the inner side of the hood portion to an outer side of the hood portion, and which retain part of the seal ring formed at the seal ring-forming portion when the elastic material is cured. An air reservoir portion is formed in a secondary mold, which communicates with outer open ends of the through holes in the connector housing in the secondary molding step.
