1. A gas turbine comprising:
an air compressor,
a turbine coaxially coupled to the compressor,
a turbine casing accommodating the compressor and the turbine,
a compressor output shaft protruding from the turbine casing towards a side opposite to the turbine,
a turbine output shaft protruding from the turbine casing towards a side opposite to the compressor,
a compressor side mounting section provided at a section of the turbine casing that is near the compressor;
a turbine side mounting section provided at a section of the turbine casing that is near the turbine, and
a rigid structure support member and a flexible structure support member that are used as a pair, wherein:
only one of the compressor output shaft and the turbine output shaft is connected to a rotary device,
the rigid structure support member is mounted to the compressor side mounting section or the turbine side mounting section, whichever is closer to the rotary device,
the flexible structure support member is mounted to the compressor side mounting section or the turbine side mounting section, whichever is more distant from the rotary device, and
the rigid structure support member is more rigid than the flexible structure support member.
