PURPOSE: A method for coupling a bucket and a vibration prevention member is provided to control swirl generation by minimizing vibration occurred when a rotor is rotated. CONSTITUTION: A method for coupling a bucket and a vibration prevention member is as follows. A vibration prevention member(10) for connecting buckets is riveted in order to prevent vibration. The vibration prevention member has upper protrusions and lower protrusions which correspond to coupling holes formed in the buckets. When the upper protrusions of the vibration prevention member are riveted on the buckets, gap retaining members are installed between the buckets and the vibration prevention member.
