Abstract
Provided is a vane tip clearance management structure for a gas turbine which allows a vane tip clearance to be confirmed easily at the time of completing assembly. For this purpose, there are provided: a casing () rotatably supporting a rotor (); stator vane retainer rings (, and) and a turbine vane ring () provided to have predetermined clearances from tips of rotor vanes (and) fitted in multiple steps to the rotor () inside in the radial direction of the casing (); guide frames () penetrating the casing (), the stator vane retainer rings (, and) and the turbine vane ring () in the radial direction and being supported by stepped portions (, and); and rods () movably supported by the guide frames () and abutting on the tips of the rotor vanes (and). Clearances (Cand C) are measured based on the amounts of movement of the rods () relative to the guide frames ().
