Abstract
A vibration-canceling mechanism includes a vibration transfer member of a plane shape inserted between a vibration-origination system having at least one resonance frequency and an object to which a vibration is applied from the vibration-origination system. The vibration transfer member has a resonance frequency equal to or near the at least one resonance frequency of the vibration-origination system. A center of one end section of the vibration transfer member is coupled by a single arm section to a center of the other end section of the vibration transfer member. The one end section of the vibration transfer member is fixed to the vibration-origination system and the other end section of the vibration transfer member is fixed to the object so that an apparent vibration of the object is substantially canceled by a resonance of the vibration transfer member.
