In a steam turbine including a rotor including a free side end fixed by a journal bearing in a radial direction and a fixed side end fixed by a thrust bearing in an axial direction, and a casing including a fixed side end fixed by the thrust bearing in the axial direction, a casing position adjustment device is configured to adjust an axial position of the casing with respect to the rotor due to thermal expansion. The casing position adjustment device includes: a low-pressure casing end plate, which is an end plate oriented to a free side in the axial direction in a low-pressure casing of the casing, and has a diaphragm deformable in the axial direction; and actuators, which are configured to deform the low-pressure casing end plate so that the low-pressure casing end plate extends toward the free side in the axial direction.

Casing position adjustment device

The shaft sealing structure includes a seal ring that has abutment portions formed by dividing the seal ring along the axial direction and that is provided around a main shaft in a ring-like manner; a support member that is provided in the seal ring along the circumferential direction of the main shaft; and a thermoswitch that is connected to the support member between the abutment portions and that presses the support member toward the center of the main shaft when the temperature rises to a temperature higher than that during normal operation, in which the seal ring is fixed at a position separated from the main shaft during the normal operation and is moved by the support member toward the center of the main shaft when the temperature rises to a temperature higher than that during the normal operation.

This compactor includes first rollers having first roller surfaces that press a laminated sheet from the second surface side of a release sheet, the first rollers being disposed separated from each other; and a second roller having a second roller surface that presses the laminated sheet from the second surface side of the release sheet, the second roller being disposed such that the second roller surface faces a gap provided between the first rollers.
