Abstract
There is provided a gas turbine capable of improving the durability of a main shaft by absorbing the deformation of a casing due to heat and pressure and suppressing stresses acting on the main shaft. A link plateof a movable supporting legthat supports a casingof a gas turbineon the turbineside is installed beforehand in an inclined manner at an angle θ, whereby the displacement X of a lower casingL in the height direction; which occurs between a pinin a top end portion of the link plateand a top surface of a lower casingL when the operation status of the gas turbineshifts from a stop condition to an operating condition is compensated for. This prevents a main shaftfrom changing in the height direction in the part of the movable supporting legand suppresses bending stresses acting on the main shaft
