pump module. The covering member closes an opening of the fuel tank formed at an upper wall part thereof. The subtank is disposed in the fuel tank. The pump module is accommodated in the subtank. The pump module includes a fuel pump and a fuel filter. The fuel pump suctions and then discharges fuel after pressurizing it, and the fuel filter is disposed to surround the fuel pump in an outer peripheral direction thereof. An electric connector is provided for the covering member so as to project from a lower surface of the covering member in a direction of gravitational force thereof toward the subtank. This electric connector is connected to another electric connector (coupler).
A connector joining device, which connects the electric connector disposed on the covering memberthat covers the opening of the fuel tank and the electric connector (coupler) as its counterpart, may have the following three constitutions. The connector joining device with the first constitution may include an electric connector including a first housing and an electric connector (coupler) including a second housing. A recess having two male terminals together is formed on the first housing, and a projection that is to be fitted into the recess of the first housing is formed on the second housing. In this connector joining device, the two male terminals that coexist in the recess and two female terminals accommodated in the projection are connected.
The connector joining device with the second constitution may include an electric connector including a first housing and an electric connector (coupler) including
