ン等におけるこもり音の低減効果をもたらす。BACKGROUND TECHNOLOGY In general, vibration isolators for vibrating bodies generally have a configuration in which an elastic body made of rubber or the like is used to provide elastic support between the vibrating body and a support body. A vibration isolation structure, usually called a dynamic damper, is known in which a vibrating body is fixed to one end of the body and an elastic body is interposed between a separately provided mass body and the vibrating body. According to the above-mentioned dynamic damper, the mass body vibrates while maintaining its natural frequency as the vibrating body vibrates, thereby providing a damping effect for photographing and an effect of reducing muffled noise in an engine or the like.
