PROBLEM TO BE SOLVED: To provide a turbine moving blade with improved platform cooling capable of further increasing the operating efficiency of a gas turbine engine. SOLUTION: This turbine blade 22 comprises an airfoil 26, a platform 28, a shank 30, and a dovetail 32 which are integrally joined to each other. A cooling chamber 58 has a portal 60 disposed under the platform 28 and exposed from the shank 30 to the outside. A damper seat 62 is recessed in the lower part of the platform 28 to receive a vibration damper 64 so as to sealingly close a chamber 58 crossing the portal 60 by surrounding the portal 60.
