A bus-bar connecting structure of a distribution board for a condominium complex is provided to prevent a fixing bolt from being released by closely contacting a bent portion with a lower inclined surface of a bus bar. Two bus bars(30,40) are arranged in a cross shape. Both ends of the bus bar are supported by supports(51,53) on a base plate. An upper press block(50) and a lower press nut are provided with a bolt hole and a screw hole. A bent portion(72) contacting between a lower inclined surface of the bus bars and a pressing surface of a lower press nut is formed on an end of the but bar. A sliding stepped portion is formed on an upper end of the upper press block. A trapezoidal contact surface is formed on a lower end of each spacing bar(90,92). |
