To obtain a wiring lead out apparatus, capable of easily connecting with it and with good appearance the power-supply lines and signal lines of OA equipment, when the OA appliances are used to put them on the top plate of a large-sized table or the top plates of assembled tables, whereto such a wiring treating structure as a desk is not given.

This wiring lead out apparatus comprises a container-form connector mounting body and a slender pole-form portions 7. The container-form body has a bottom portion (1), having its opening portion (2) for leading wiring into it from its bottom surface whose plan view is a polygon or circle, a standing wall portion 3 of a wall which stands annularly along the outer periphery of the bottom portion (1) on whose wall surface there are formed a plurality of connector providing holes (4), whereinto connectors 5 are fitted to direct outward their plug inserting ports, and a top plate portion 6 formed on this annular standing wall portion 3. Each slender pole-form portion 7 is joined to the foregoing bottom portion (1) so as to communicate with the opening portion (2) and stores in its hollow portion wirings connected with the connectors 5. Furthermore, by setting it self-standing each slender pole-form portion 7 through providing a leg 7a at its lower end, the foregoing connector mounting body is put on the assembled corner portions of assembled tables T1-T3 or is placed adjacent to the assembled tables T1-T3 to enable equalization of the providing levels of its bottom surface portion (1) and the top-plate surfaces Tb1-Tb3 of the tables T1-T3.
