摘要： In a turbine blade, for a snapper cover provided on the top blade portion of the effective blade portion of the turbine blade and a snapper cover provided on the top blade portion of the effective blade portion of a turbine blade neighboring to the above-described turbine blade, contact surfaces composed of plural side-surfaces are formed in a crank shape, respectively. In these surfaces constituting the contact surfaces, a contact-friction surface of the snapper cover which is brought into contact with a contact-friction surface of the other snapper cover has a positive angle of inclination in the rotation direction of the effective blade portion. According to this structure, there is provided a turbine blade in which the contact surfaces of the snapper cover and the neighboring snapper cover are maintained in the contact-state during the driving of the turbine, and the same vibration mode as that in the rotational direction of the effective blade portion can be sufficiently controlled.
