    • It is intended to develop a technique of pressing and fixing a plate by a uniform force to suppress the occurrence of a crack around a nozzle hole of the plate during use, and provide a sliding nozzle device capable of improving durability of the plate, and a plate for use in the sliding nozzle device. The sliding nozzle device comprises a plate (2) and a plate-receiving metal frame (1) for fixedly holding the plate (2). The plate-receiving metal frame (1) is equipped with: at least two holding members (3) each having two pressing surfaces (31, 32) consisting of a longitudinally-pressing surface and a laterally-pressing surface which are protrudingly provided thereon in spaced-apart relation to each other and each adapted to be brought into contact with a corresponding one of a plurality of side surfaces of the plate (2), wherein the holding members (3) are symmetrically arranged with respect to a longitudinal axis of the plate-receiving metal frame (1); a movable block (6) rotatably supporting the holding members (3); and pressing means adapted to press the movable block (6) toward the plate. An angle between the longitudinally-pressing surface (31) and the longitudinal axis of the plate-receiving metal frame (1) is set in the range of 60 to 90 degrees, and an angle between the laterally-pressing surface (32) and the longitudinal axis of the plate-receiving metal frame (1) is set in the range of 1 to 30 degrees.
