摘要： A process for producing an exterior member/seal member assembly includes: a first step of moving a slide core to protrude into a major cavity defined between first and second dies and, and injecting a hard synthetic resin into an exterior-member forming cavity partitioned in the major cavity; and a second step of retracting the slide core and injecting a soft synthetic resin into a seal-member forming cavity which is a remaining portion of the major cavity. An outer-seal-lip forming portion is connected to an outer end of the seal-member forming cavity; a recess-shaped step is formed on one side face of the slide core and adapted to define an inner-seal-lip forming portion leading to the seal-member forming cavity between the step and an inner surface of a guide bore in the second die when the slide core is retracted; and the soft synthetic resin is filled into the outer and inner-seal-lip forming portions 15 and 16 at the second step. Thus, the seal member having the pair of inner and outer seal lips can be formed and coupled to the exterior member by one stroke of the seal-member forming step, and complication of the forming step can be avoided.
