Abstract
A lower half inner casing has a lower half inner casing body forming a semi-circular arc, and an inner casing accessory part provided to the lower half inner casing body. The inner casing accessory part has a protrusion which protrudes radially outward of the lower half inner casing body, and protrudes upward of a lower contact surface of the lower half inner casing body. In the deformation adjustment method, the following are executed: a preparation step for preparing a deformation adjustment device having an inner casing-side member that is attachable to the protrusion so as to be non-relatively movable in the radial direction; a device arrangement step for attaching the inner casing-side member to the protrusion and arranging the deformation adjustment device around the protrusion; and a deformation adjustment step for pressing, to the radial inward side, the inner casing-side member attached to the protrusion.
