ABSTRACT:
At least one cavity is formed extending along the axis of rotation of a rotor. One or more elastic members are fitted into the cavity to balance the rotor. Once the elastic members are inserted in the cavity, they apply their own elasticity to the inner wall of the cavity, so that they are stably held in the cavity.
