PROBLEM TO BE SOLVED: To provide a casing-combustion chamber coupling capable of absorbing displacement occurring due to a difference in an expansion factor of a part. SOLUTION: A turbo machine contains shells 12 and 14 of a metal material and the shells contain a metal material sector division nozzle 42 to form an inlet step having fuel injection assemblies 20 and 22, a composite material combustion chamber 24, and a fixed blade 44 of a high pressure turbine in a direction F of a gas flow. The combustion chamber is held by sector division flexible sleeves 56 and 60 of a metal material. The sleeves have respective one ends 56a and 60a fixed at a combustion chamber by first fixing means 50 and 52, and ends 56b and 60b on the opposite side fixed at the shells by second fixing means 54 and 58 to form a flange. The first fixing means also functions to couple the combustion chamber to the sector division nozzle.
