A wiring device for a desk leg in which a cord insertion passage is recessed back-to-back with each other through upper and lower longitudinal partition wall plates that partition the middle of the leg in the thickness direction from the inside to the outside. A passage body made of synthetic resin is disposed in the cord insertion passage along the cord insertion passage, and the upper and lower ends are open, and the passage body is formed so as to have a plurality of vertical longitudinal grooves that are open to the wide outer surface or inner surface of the leg body. The passage body is configured to be detachably attached to the partition wall plate via a clamping means that clamps the passage body.

[Functions and effects of the invention]

As described above, according to the present invention, the passage body disposed in the cord insertion path along the vertical and longitudinal partition wall plates is detachably provided via the clamping means that clamps the cord insertion path with respect to the partition wall plate. Moreover, since each passage body is open at its upper and lower ends and is provided with a plurality of vertical longitudinal grooves that open to the wide outer surface or inner surface of the leg body, the number of vertical longitudinal grooves is By preparing various passage bodies with different passage bodies, it is extremely easy to change the number of channels for cord insertion by simply replacing the passage bodies, and this replacement work can also be done easily by the user. This has the effect that it can be done.

In addition, since the passage body is made of synthetic resin and has electrical insulation properties, even if the legs are made of metal, there is no contact with metal parts at the passage point, reducing the risk of electrical short circuits. be.
