To do. Then, the device housing 30 and the device housing 40 can be attached to the switch box 20 through the connection attachment metal fitting 10 in a relationship of being connected to each other.

[0009]

However, the connecting attachment metal fitting 10 is provided only with the attachment screw hole 10b corresponding to the attachment holes 32, 42 of the specified device housings 30, 40. Therefore, in the conventional connecting fitting,
It is not versatile, and it is no longer possible to connect and attach when the device housings have different widths, and it is inconvenient to separately prepare a connecting and attaching metal fitting suitable for the device housing each time. There was a problem to say.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a convenient and versatile connecting attachment fitting.

[0011]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a connecting and attaching metal fitting for arranging and attaching a plurality of objects to be attached side by side. An attachment part that fits the attachment part of the object, a pair of parallel attachment slits having an interval corresponding to the attachment interval of the attachment parts of the plurality of attachments, and moving along the attachment slit. A nut to
A nut accommodating portion for accommodating the nut slidably along the attachment slit is provided.

[0012]

With the above-described structure, the width of the attachments and the attachment of the attachments can be adjusted by setting the attachment intervals of the attachments of the respective attachments to match the distances between the pair of attachment slits. Regardless of the position of the attachment portion, the attachment can be attached and attached to the attachment target through the attachment fitting.
