(57) [PROBLEMS] To obtain sufficient airtightness and durability simply by bringing the housing and the cable into close contact with each other at the same time as the injection molding of the housing without using special parts. SOLUTION: As a sheath material of a cable 6, a cross-linked body of a resin composition mainly composed of flame-retarded thermoplastic polyester elastomer is applied, and a housing 3 is formed by melting and molding a PBT resin. The cables 6 are hermetically sealed. Since the sheath material of the cable 6 made of the resin composition mainly composed of the thermoplastic polyester elastomer is adhered to the housing 3 when the housing 3 is melt-molded, sufficient airtightness between the housing 3 and the cable 6 is obtained. The required waterproof performance can be achieved. |
