PROBLEM TO BE SOLVED: To downsize and simplify a distribution board by forming a pair of wheels which are guided to a pair of guide rails at the lower parts on both sides of an operating part, integrally forming a pair of sliders guided to a pair of guide rails at the lower parts on both sides of a polar pole with an insulating member. SOLUTION: The main body of a distribution board is provided with a circuit breaker chamber. A pair of guide rails 11 are laid on the floor of the circuit breaker chamber and a draw-out type circuit breaker 3, capable of being carried in and out, is accommodated in the circuit breaker chamber. The draw-out type circuit breaker 3 is constituted of a polar pole 8, formed by surrounding a breaking part 6 with an insulating member 7 and an operating part 9 which operates the breaking part 6. A pair of wheels 5 guided to a pair of guide rails are formed at the lower parts on both sides of the operating part 9, and a pair of sliders 10 guided to a pair of guide rails 11 are formed integrally with the insulating member 7, at the lower part on both sides of the polar pole 8. Thus the distribution board can be downsized and simplified.
