A method for manufacturing a variable vane including a planar blade unit and a columnar shaft unit positioned under the blade unit, the method comprising the step of: pressing a sinter having a shape approximate to that of a desired final product; wherein the sinter is integrally constituted of the blade unit and the shaft unit, and has the height of the blade unit within +0.3% to +0.9%, the thickness of the blade unit within -0.6% to -0.0%, the diameter of the shaft unit within +0.3% to +0.9%, the length from the lower end of the blade unit to the lower end of the shaft unit within -0.6% to -0.0% with respect to the target dimensions of the final product, and a sintering density, meaning a relative density, of 95% or more, and wherein the pressing process includes three processes: in a first pressing process, the sinter is pressed with a lower die having a shaft unit insertion hole and an upper die having a shape except a lower end surface of the blade unit, so as to adjust the height and thickness of the blade unit; in a second pressing process, the blade unit and shaft unit of the sinter are pressed at the same time with an upper die and a lower die, each of which has a shape obtained by dividing the variable vane at a surface at which the thickness of the blade unit is bisected, so as to adjust the angle of the shaft unit with respect to the blade unit and the coaxiality of the shaft unit with respect to the blade unit; and in a third pressing process, the shaft unit of the sinter is pressed in a direction turned at 90° from that in the second pressing process with an upper die and a lower die, each of which has a semi-columnar shape corresponding to the shaft unit of the variable vane, so as to adjust the roundness of the shaft unit. pressing a sinter having a shape approximate to that of a desired final product; wherein the sinter is integrally constituted of the blade unit and the shaft unit, and has the height of the blade unit within +0.3% to +0.9%, the thickness of the blade unit within -0.6% to -0.0%, the diameter of the shaft unit within +0.3% to +0.9%, the length from the lower end of the blade unit to the lower end of the shaft unit within -0.6% to -0.0% with respect to the target dimensions of the final product, and a sintering density, meaning a relative density, of 95% or more, and wherein the pressing process includes three processes: in a first pressing process, the sinter is pressed with a lower die having a shaft unit insertion hole and an upper die having a shape except a lower end surface of the blade unit, so as to adjust the height and thickness of the blade unit; in a second pressing process, the blade unit and shaft unit of the sinter are pressed at the same time with an upper die and a lower die, each of which has a shape obtained by dividing the variable vane at a surface at which the thickness of the blade unit is bisected, so as to adjust the angle of the shaft unit with respect to the blade unit and the coaxiality of the shaft unit with respect to the blade unit; and in a third pressing process, the shaft unit of the sinter is pressed in a direction turned at 90° from that in the second pressing process with an upper die and a lower die, each of which has a semi-columnar shape corresponding to the shaft unit of the variable vane, so as to adjust the roundness of the shaft unit. in a first pressing process, the sinter is pressed with a lower die having a shaft unit insertion hole and an upper die having a shape except a lower end surface of the blade unit, so as to adjust the height and thickness of the blade unit; in a second pressing process, the blade unit and shaft unit of the sinter are pressed at the same time with an upper die and a lower die, each of which has a shape obtained by dividing the variable vane at a surface at which the thickness of the blade unit is bisected, so as to adjust the angle of the shaft unit with respect to the blade unit and the coaxiality of the shaft unit with respect to the blade unit; and in a third pressing process, the shaft unit of the sinter is pressed in a direction turned at 90° from that in the second pressing process with an upper die and a lower die, each of which has a semi-columnar shape corresponding to the shaft unit of the variable vane, so as to adjust the roundness of the shaft unit.
