), the backing 33 contacts the peripheral edge 34 of the opening in the mounting surface.

Generally, three sides of the mounting 33 excluding the upper side of the peripheral edge 34 and the transverse portion 35 abut against the opening edge of the mounting surface in which the embedded box is embedded.

Therefore, it seems that the section up to the crossing section 35 is necessary for the sailing 33, and the section above that is unnecessary.

However, if the upper part of the backing 33 is removed from the cross section 35, the backing 33 will no longer fit the dimensions of the bulky member 18, and will not be waterproof even if it is installed in either an exposed type or a buried type wiring box. There is a problem that it cannot be installed.

However, in the present invention, since the backing 33 is formed in a size that fits into the periphery of one end surface of the mounting frame portion 17, reliable waterproof installation is possible in both exposed type and recessed type installations. It becomes possible.

Alternatively, after attaching the support 8 to which the instrument body 7 is attached to the box 1, the attachment frame member 17 of the part 16 can be attached to the support 8.
