ABSTRACT:
A shroud segment for being incorporated in a gas turbine engine having a turbine case and a rear turbine case connected with a rear end of the turbine case so as to suppress influence of hot combustion gas on the turbine case and the rear turbine case, is provided with a back plate formed in an arc shape and supported by the turbine case, a touching member integrally formed on an inner surface of the back plate for touching with a rotating turbine blade; and a jet shield extended from a rear end of the back plate and slanted radially inward so as to shield the rear turbine case from a jet of the hot combustion gas.
