のシール装置。A plurality of stator vane segments consisting of an arc-shaped outer end wall, an inner end wall, and a plurality of stator vanes fixedly installed between both end walls are arranged in the circumferential direction inside the casing to form an annular stator vane section. A sealing device for preventing cooling air from leaking to the working fluid side is provided between the stator vane segments adjacent to each other, and the sealing device column, the circumferentially adjacent surfaces of the mutually adjacent outer end walls, and the inner side thereof are provided. In a fluid machine comprising grooves provided on adjacent surfaces in the circumferential direction of an end wall, and seal plates inserted into each groove, the grooves are formed into a tapered shape in the circumferential direction, and the seal plates are , a square-shaped seal plate is used, and a contact portion is formed between the seal plate and the inner surface of the groove by elastic deformation of the seal plate without restricting the circumferential thermal expansion of the stationary vane segment due to temperature rise. A sealing device for a stator vane in a fluid machine, characterized in that:
