PROBLEM TO BE SOLVED: To provide a distribution board, wherein backlashes are hard to occur between the power-supply terminal port of a branching breakers and branching bars. SOLUTION: In a distribution board 1, branching breakers 2 for dividing the power supply from a main breaker and supply the power to each load circuit are arranged in two lines at an arbitrary interval under a state, wherein power-supply terminals are made to face each other in the right and left symmetry or vertical symmetry in the inside of the main body of a box body. The main breaker and the branched breaker 2 are connected with a unitary-type conducting bar 3, wherein a main bar and a branching bar are formed as a unitary body, and a branching bar 7, wherein a main bar 4 and a branching bar 5 are screwed with screws 6. In the vicinity of an end part 5a of the branching bar 5, which is inserted into a power-supply terminal port 2a of the branching breaker 2, a width-expanding part 5c, which is equal to the width of the power-supply terminal port 2a, is provided. |
