PURPOSE: To provide an integral shroud blade for adjusting the barycenter of the shroud in tangential direction. CONSTITUTION: The blade described comprises a root portion for mounting the blade in a row on a turbine rotor, a platform portion, an airfoil portion 16 extending upwardly from the platform portion and having a leading edge 18, a trailing edge 20 and a tip, a shroud 32 formed on the tip of the airfoil portion 16 and having two opposite tangential side surfaces 34, 36 and a top surface 38, and at least one pair of holes 40, 42. Each of the two tangential side surfaces 34, 36 of the shroud 32 has one hole of each pair of holes 40, 42 being formed therein. |
