PURPOSE: To enhance productivity and reliability, by fitting an internal-toothed washer on a terminal.
CONSTITUTION: After a bobbin 11 is inserted into an assembly of a yoke 2 and a core 20, an O-ring 15 for fuel sealing and a terminal guide 16 are fitted on a terminal 17. An internal-toothed washer 23 is then fitted on the terminal 17 to secure the bobbin 11 integrally coupled to the terminal 17. The inside diameter d2 of the washer 23 and the outside diameter d1 of the terminal are related to each other as d2<d1, and the washer 23 can be elastically deformed. For that reason, the washer 23 can be relatively easily fitted on the terminal 17, but cannot be easily pulled out from the terminal in the direc tion of pulling-out of the bobbin 11.
