Abstract
Turbine blade of gas turbine etc. and gas turbine equipment using the turbine blade suppress occurrence of thermal stress caused by temperature difference and provide high reliability. In gas turbine equipment comprising rotational portion of rotor ( ) and moving blade ( ), stationary portion of casing ( ), stationary blade ( ), various supporting members, etc. and combustor, thermal stress reducing portion is provided in any one or both of moving blade joint adjacent portion ( ) between moving blade trailing edge portion ( ) and platform ( ) and stationary blade joint adjacent portion ( ) between stationary blade trailing edge portion ( ) and shroud ( ). By the thermal stress reducing portion, undesirable thermal stress occurring in the blade joint adjacent portions ( ) is reduced and reliability of the turbine blade and the gas turbine equipment is enhanced.
