摘要： Such a rotating blade body is supplied as can prevent not only local wear and deformation but also inadvertent vibration and can maintain cooling efficiency. A rotating blade body consists of a rotor disc 2 and rotating blades 1 which are assembled so as to extend from the outer circumference of the rotor disc 2 in a radial pattern, wherein blade root portions 10 of the rotating blades 1 are engaged into blade grooves 20 which are formed along a direction of a rotating shaft on an edge of the outer circumference of the rotor disc 2. Circulation spaces 25 for the cooling air are formed along the direction of a rotating shaft between the bottom-end portions 10a of the blade root portions 10 and the bottom portions 20a of the blade grooves 20. Pushing-up members 3 which push up the rotating blades 1 outward in a radial direction are inserted into the circulation spaces 25, maintaining circulation of the cooling air.

摘要： The present invention includes an introducing passage that is provided within a turbine stationary blade fixed within a turbine casing and that communicates an interior of the turbine casing with an exterior thereof; a nozzle that is provided in an inner circumference of the turbine stationary blade in a manner that the nozzle communicates with the introducing passage and that includes an outlet facing the opening of the rotor cavity and a swirler at the outlet; and a pressurizing passage that communicates a cooling passage with a rotor cavity. In this arrangement, the outlet of the nozzle and the connecting opening of the pressurizing passage are arranged so that distances of the outlet and of the connecting opening from the central axis line in the radial direction of the rotor are the same distance r.
