Abstract: A sliding nozzle device that can reduce any damage such as surface roughness and chipping in a nozzle hole surroundings of a used plate. The sliding nozzle device includes a fixed metal frame, a sliding metal frame, and an opening and closing metal frame that holds the sliding metal frame in a slidable manner, and in the sliding nozzle device in which sliding contact surfaces of the sliding members provided on the sliding metal frame and the opening and closing metal frame come in slidable contact with each other, the sliding contact surfaces of the sliding member of the sliding metal frame are provided away from each other by a predetermined length front and rear in the sliding direction and a part between the front and rear sliding contact surfaces serves as a depressed part, and the sliding contact surfaces of the sliding member of the opening and closing metal frame are provided away from each other by a predetermined length front and rear in the sliding direction and a part between the front and rear sliding contact surfaces serves as a depressed part.
