の接続部。 Bolts are provided so as to pass through the overlapping parts of the bus bars to be connected, the overlapping parts of the duct connection plates, the insulating plates inserted between them, the spring members for absorbing thermal expansion and contraction, etc., and the nuts are attached to the tips of the bolts. In the connection of a bus duct formed by screwing and tightening, the tip of the bolt and the deep part of the threaded hole of the nut are respectively formed with abutment surfaces that come into surface contact with each other when the proper tightening state is reached, and the nut is tightened. A bus duct connection part characterized in that the abutment surface is tightened so as to abut the abutment surface of a bolt.
