Abstract
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 discand rotating bladeswhich are assembled so as to extend from the outer circumference of the rotor discin a radial pattern, wherein blade root portionsof the rotating bladesare engaged into blade grooveswhich are formed along a direction of a rotating shaft on an edge of the outer circumference of the rotor discCirculation spacesfor the cooling air are formed along the direction of a rotating shaft between the bottom-end portionsof the blade root portionsand the bottom portionsof the blade grooves. Pushing-up memberswhich push up the rotating bladesoutward in a radial direction are inserted into the circulation spaces, maintaining circulation of the cooling air.
