However, in this coil assembly, the flange of the bobbin has an outer diameter slightly smaller than the inner diameter of the coil holder, and the inner diameter of the center hole of the bobbin is also slightly larger than the outer diameter of the protrusion of the coil holder. Therefore, when a bobbin with a coil wound thereon is assembled into a coil holder before injection of resin material for molding, the space between the inner diameter surface of the coil holder and the outer diameter surface of the bobbin flange, as well as the protrusion of the coil holder. The end surface of the flange of the bobbin is in close contact with the outer diameter surface of the bobbin and the inner diameter surface of the center hole of the bobbin or the inner bottom surface of the coil holder, and there is almost no space between the end surface of the bobbin and the inner bottom surface of the coil holder. It is in a state where it is not formed.

者によつて見い出された。 Therefore, when resin molding this coil assembly, the distance between the outer diameter surface of the protrusion of the coil holder and the inner diameter surface of the center hole of the bobbin must be Since the diameter is smaller than that between the outer diameter of the protrusion of the coil holder and the inner diameter of the center hole of the bobbin, and between the end surface of the bobbin and the inner bottom surface of the coil holder, resin will not flow in. There is a risk that the protrusion of the coil holder and the bobbin cannot be reliably sealed with the molded resin, and as a result, the bobbin may slip out of the coil holder in the axial direction, making it impossible to fix the solenoid coil. The present inventor discovered that there is.
