Abstract
A turbine rotor blade comprises: a blade effective part; a snubber disposed on radially outer side of the blade effective part; a platform disposed on radially inner side of the blade effective part; and an implanted part disposed on radially inner side of the platform. A first flow path is formed inside the implanted part for a cooling medium to pass through. A second flow path is formed inside the platform for the cooling medium having passed through the first flow to pass through. A blade effective part flow path is formed inside the blade effective part for the cooling medium having passed through the second flow path to pass through. A snubber flow path is formed inside the snubber for the cooling medium having passed through the blade effective part flow paths to pass through.
