Abstract:
1. A method of manufacturing a waterproofing device for a mobile apparatus, the method comprising: a step of entirely inserting cylindrical reinforcement members into an inner peripheral surface side in the vicinities of end parts of a connecting member molded in a circular tube-like shape with a soft resin material such that the connecting member extends on both sides of the reinforcement members; after inserting the cylindrical reinforcement members into the connecting member, a step of integrally molding seal members consisting of a rubber-like elastic material for sealing a gap between housings on an outer peripheral surface of the connecting member where the reinforcement members have been placed by using a metal mold, the reinforcement members having an axial length corresponding to a region of the connecting member which the metal mold contacts during molding of the seal members, the rubber-like elastic material being different from the soft resin material; and after molding the seal members to the connecting member, a step of inserting a linear member for connecting the housings to each other into the connecting member, the axial length of each reinforcement member is larger than a width of a part of each seal member molded to the connecting member.
