During this time, the length of the temporarily assembled connecting cylinder portions 9 and 10 is adjusted to a length corresponding to the battery connection terminal 1a while sliding with each other.

Subsequently, after closing and locking the connecting tubular portions 9 and 10 of both the cover components 6 and 7, the insertion holes 4 of both connecting members 3 are inserted into the battery posts 51. At this time, if there is a deviation in the pitch between the battery posts 51 and the two insertion holes 4 of the battery connection terminal 1a, similarly, the user pulls the cover 5 at both ends and pulls it outward, or pushes the cover 5 inward to connect the connecting cylinder. When the lengths of 9, 9 are adjusted, the pitch between the two insertion holes 4 is adjusted to the pitch between the battery posts 51 while the braided electric wire 2 of the battery connection terminal 1a is bent and deformed.
Is inserted through the battery post 51. Similarly, utilizing the fact that the lid 28 is open, a seat nut 54 is screwed and fastened to the upper end of the battery post 51 and fixed. Finally, when the lid 28 is closed and locked, FIG. As shown in the figure, the battery post 5 of the adjacent battery 50a
1 are connected by the battery connection terminal 1a, and the battery connection terminal 1a is covered by the cover 5.

Conversely, when the pitch between the two battery posts 51 to be connected is small, a battery connection terminal corresponding to the pitch is prepared, and the connecting tubular portion 9 of the cover 5 is
10 may be adjusted to a corresponding length. In addition, it is possible to cope with a case where the pitch between the battery posts changes according to the arrangement of the batteries.

As described above, according to the present embodiment, when the pitch between the battery posts 51 to be connected is changed, the battery connection terminals 1 and 1a corresponding to the change are prepared, while the cover 5 is connected. It is easy to cope simply by adjusting the length of the cylindrical portions 9, 10 while expanding and contracting them. Even if the pitch between the battery posts 51 is shifted, the braided electric wires 2
By adjusting the length of the connecting tube portions 9 and 10 while sliding the connecting tube portions 9 and 10, the pitch between the two insertion holes 4 can be matched with that between the battery posts 51. It can be performed. That is, there is no need to re-install the battery every time.

In a state where the two cover components 6 and 7 are temporarily assembled, one side surface is opened over the entire length, and the battery connection terminals 1 and 1a can be fitted from the side. The work of mounting the terminals 1 and 1a can be simplified. Lid 2 that can be opened and closed
