<P>PROBLEM TO BE SOLVED: To provide a vibration control structure for suppressing the vibration and noises of a structure such as a motor which is affected by electromagnetic force. Ž<P>SOLUTION: In the vibration control structure for a cylindrical structural object that receives the effects of electromagnetic force, a cylindrical body 2a that configures the structure has hollow portions 4, and vibration damping materials 5 are built in the hollow portions 4. The plurality of hollow portions 4 of roughly the same shape are formed at roughly uniform spaces in the circumferential direction of the cylindrical body 2. The vibration damping material 5 is configured from a plurality of granular bodies 6, or a plurality of granular bodies 6 and viscoelastic bodies 7. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
