Abstract
A steam turbine casing includes a lower half part having a plurality of lower support portions projecting horizontally around a lower half part body; an upper half part connected onto the lower half part; a support member fixed to an upper surface part of a respective one of the lower support portions; and a plurality of support columns each having a lower end part on a frame and an upper end part to which a lower surface part of the support member fixed to a corresponding one of the lower support portions. Thus, thermal deformation of the casing is suppressed, and a suitable clearance can be maintained between the casing and a turbine.
