PROBLEM TO BE SOLVED: To reduce defects in a conventional technique by suggesting a moving blade for a high pressure turbine having a new shape to prevent cracks, to prevent lowering of mechanical strength as a whole of the blade to be a part applied with extremely large mechanical stress, and to provide the high pressure turbine for a turbomachine. SOLUTION: The moving blade has a cooling circuit including a cavity extending radially between a distal end part of the blade and a base part, an air inflow opening at a radial end part of the cavity for supplying cooling air to the cooling circuit, and a plurality of slots 26 opening to the cavity and opening to a concave surface side 16A of the blade. A connection region 30 is provided between a slot 28 closest to the base part of the blade and an upper surface 22A of a platform 22. The moving blade is provided with cooling air exhaust auxiliary slots 32 and 34 opening to the cavity and opening to the connection region 30 in line with the rear edge 20. COPYRIGHT: (C)2003,JPO
