不具合がある。However, since the bus duct housing is relatively long and heavy, the work of assembling the bus duct in which a water-expandable foam material or a spacing adjusting member is interposed at the joint becomes complicated, resulting in poor workability and low production cost. The bus duct housing does not have sufficient mechanical strength because the housing halves facing each other are only connected to each other by bolts, especially when an external force such as a load or impact acts on the reinforcing portion. There is a problem that deformation may occur.

る。In all of the conventional bus duct housings described above, the outer end surface of the reinforcing portion 101c is formed in the housing recessed portion 1c.
01a is projected outwardly from the outer side surface portion of the bus duct 01a, and is not configured to be flush with each other. Therefore, in a state where the bus duct is horizontally arranged, the load on the entire bus duct is reduced by the housing recess for housing the insulated conductor. And the reinforcing portion is not distributed and supported, and the entire load is applied to the outer end surface of the reinforcing portion 101c.

There has been a demand for prevention of the reduction and the reduction of the electrical safety. Further, in the shape in which the reinforcing portion protrudes, the sectional shape of the occupied space is not formed in a substantially rectangular shape, so that the packing of the bus duct is not easy and the loading of the bus duct cannot be stabilized.
