A load distribution member for the turbine of a gas turbine engine comprises an annular diaphragm between regions P1 and P2 of high and low gas pressure respectively which is in the form of a part of a complete thin shelled toroid having a circular cross-section area of revolution. The radially outer edge of the annular diaphragm has a ring member attached thereto which is attached in turn to the undersides of an annular array of stator aerofoil vanes. The radially inner edge of the annular diaphragm has a ring member attached thereto which carries one element of an annular gas seal. The other element of the seal is attached to a rotary part of the turbine. The configuration of the part-toroid shape of the diaphragm is selected so that the axial forces exerted by the diaphragm upon the radially inner ring member are zero, thereby minimizing the degree of axial deflection of the seal element.
