PURPOSE: A duct side plate structure for a bus duct is provided to improve ground performance by connecting the housing of the bus duct with a wing access method. CONSTITUTION: A duct side plate(250) connects a duct part and the joint housing of a joint kit. The duct side plate includes a joint kit connection part(251), a slope part(252), a sealing plane part(253), an end block connection part(254), and a duct connection part(255). The joint kit connection part is combined with the joint housing. The end block connection part is bolt-combined with the end block for connecting the duct part. The duct connection part is connected to an upper duct and the wing part of a lower duct to perform an external ground connection function.
