<P>PROBLEM TO BE SOLVED: To provide a rotor blade support structure preventing the concentration of stress near a rotor blade groove in which a rotor blade is embedded, while suppressing an increase in production cost. <P>SOLUTION: In the rotor blade support structure, the rotor blade 30 is embedded in the rotor blade groove 10 provided on a rotor disc 1. The rotor blade groove 10 is provided with circular direction grooves 13 that extend more in the circular direction of the rotor disc than upward from a bottom 14, and shaft center direction grooves 15 that are provided on end faces 1a, 1b of the rotor disc 1 in the center of the bottom 14 in the circular direction of the rotor disc and that extend towards the rotor disc shaft center. <P>COPYRIGHT: (C)2013,JPO&INPIT |
