PROBLEM TO BE SOLVED: To limit deviation of a rotor shaft to minimize a torque load applied to a fun case from the rotor shaft when a fun blade is lost. SOLUTION: A hardening fun case liner 42 is provided inside a fun storing case assembly 30 for a gas turbine engine. A fun blade top part gets rotatable along a circumferential direction in the periphery of a fun case 48 by the fun case liner 42 at the time of generation of a fun blade lost condition. By this manner, the liner 42 reduces a cut and fracture of the fun case 48, reduces damage of the fun case 48 to the minimum, and reduces a torque load applied to the fun case 48 due to rotor deviation. |
