Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbine blade damper having a high strength and enhanced abrasion resistance. SOLUTION: The damper is characteristically equipped with an outer part 38 with the dimension given so as to extend from a platform 14 into an aerofoil 12, an inner part 40 mounted at the nearer end of the outer part 38 and extending downward from the nearer end so as to be held within the blade(s) below the platform 14, and portions 38 and 40 formed from different materials and achieving frictional damping inside the aerofoil 12 and a tensile support below the platform 14.
