<p>A turbine moving blade, wherein a contact face formed of a plurality of end faces so as to be formed in a generally crank shape is formed on a snubber cover installed at the blade top part of one blade effective part and a snubber cover installed at the blade top part of the adjacent blade effective part, and a positive tilt angle relative to the rotating direction of the blade effective part is given to a contact abrasive surface as the contact surface of one snubber cover with the other snubber cover among the surfaces forming the contact surfaces, whereby the contact surface of one snubber cover with the adjacent snubber cover is continuously maintained in contact state at all times during the operation, and a vibration mode in the same direction as the rotating direction of the blade effective part can also be damped sufficiently.</p> |
