To facilitate mounting of rotating blades provided with axial base parts by providing a mounting device with a radially outer head part having an axial groove corresponding to an axial base part of each rotating blade, and a radially inner foot for mounting in an annular groove annularly extending around a rotor.
A mounting device 6 comprises a foot part 7 and a head part 8. The head part 8 is provided with an axial groove 11b formed corresponding to an axial groove 11a of a rotor 10, and a base part 1A of a rotating blade 1 is inserted therein. Since the mounting device 6 is inserted from a radial direction into an annular groove 12a of the rotor 10 together with the rotating blade 1, the foot part 7 of the mounting device 6 is formed corresponding to the annular groove 12a. After insertion, the mounting device 6 is circumferentially slide to position the axial groove 11b of the mounting device 6 in front of the axial groove 11a of each rotor 10, and the whole row of the rotating blades is pushed into the axial groove 11a of the rotor 10. After insertion, the mounting device 6 is taken out of an insert opening in the annular groove 12a of the rotor 10.
