The connector terminals 19f to 19j of the circuits M and N which are connected without passing through are provided.

Of the electrical components 1 (1f to 1j) that are directly connected to the battery B without passing through the starter switch SW, the room lamp 1i and the clock 1j are used when the vehicle is not driven for a long time and is suspended. During that period, there is a risk that the battery B will be consumed unnecessarily due to the conduction of the dark current, so this must be prevented.

As a conventional method for preventing the consumption of the battery B by the dark current, as shown in FIG. 7, among the fuses 5 housed in the respective insertion portions 21 formed in the fuse box 3, the room lamp is used. A method is known in which specific fuses 5i and 5j (see FIG. 6) connected to 1i and timepiece 1j are removed.
