Abstract

PURPOSE:To eliminate a gap between a coil bobbin and a cover body by fusion- sticking the end faces of the coil bobbin and cover body by injection molding. CONSTITUTION:A resin material mainly composed of polyamide containing 5- 30wt% of nitrorubber is used to mold a coil bobbin 2. A resin material mainly composed of polyamide is melted and molded by inserting the coil bobbin 2 and covering the whole body. Accordingly, the interface between the coil bobbin 2 and body cover 4 is melted in one body, and the seal between the coil bobbin 2 and body cover 4 can be made complete.
