PROBLEM TO BE SOLVED: To provide a charging unit supporting stage for the distribution board that reduces the number of parts, assembling time, and manufacturing cost. SOLUTION: A charging unit supporting stage 1 has supporting parts 3 and 5. At least one part 3 of the supporting parts has a screw hole 4 for fixing a bus duct by screwing, while the other part 5 has a booking member 6 with an L-shaped cross section for locking the bus duct. On the other hand, the bus duct has a screw passing hole and a locking hole corresponding to the screw hole 4 and the locking member 6 of the charging unit supporting state 1. At least one charging unit supporting stages 1 has a locking member 6 reversely formed from those of the other charging unit supporting stages 1. A bus duct mounted on the supporting part 5 is locked by the locking member 6, and another bus duct mounted on the supporting part 5 is fixed by screwing using the screw hole 4 so that the bus duct is fixed to the charging unit supporting stage 1. |
