Abstract: An electric fuel pump includes a pump unit, motor unit, fuel discharge unit, stator holder, magnet wire, connection terminal, first mold resin, driver board assembly, and second mold resin. The fuel discharge unit includes a discharge port member and discharges fuel supplied from the pump unit through the motor unit. The stator holder is provided to the motor unit and includes a partition which defines the motor unit and the fuel discharge unit. The partition includes a terminal insertion hole and a fuel passage. The connection terminal is connected to the magnet wire. The driver board assembly is stored in a space formed in the discharge port member and electrically connected to the connection terminal. The second mold resin molds the driver board assembly and a connecting portion where the driver board assembly is connected to the connection terminal.

Abstract: A terminal engagement-insertion portion for an electromagnetic coupling device to be inserted into the through hole of a yoke is provided with two terminal holding portions and each of which has a coil engagement-insertion groove and a terminal engagement-insertion hole. In addition, an insertion portion to insert the guide portion of a terminal housing thereinto is defined between the terminal holding portions. While the guide portion is being inserted into the insertion portion, the terminals are electrically connected with the ends of an exciting coil, respectively.
