Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a structure of a platform designed to reduce the stress and the temperature of the moving blade platform. SOLUTION: In this turbine moving blade comprising a blade, the platform in the boundary between the blade and a root, and a platform cooling part, the platform cooling part comprises cooling passages 224, 226 formed in the platform and extending along at least a part of the pressure side 228 of the recessed surface of the blade, a cooling medium inlet extending from blade cooling medium hollows 230, 244 near the axial center of the blade and led to the cooling passage, and outlets 242, 248 for discharging a cooling medium through the cooling passages.
