Abstract: An anti-vibration device is secured to a vibration source and a vibration transmission portion to inhibit transmission of vibration, and includes a first elastically deformed portion, a second elastically deformed portion and a third elastically deformed portion. The first elastically deformed portion is a plate having a thickness in a first thickness direction and vibrates in the first thickness direction to configure a path for the vibration to be transmitted from the vibration source to the vibration transmission portion. The second elastically deformed portion is a plate having a thickness in a second thickness direction intersecting the first thickness direction and vibrates in the second thickness direction to configure the path. The third elastically deformed portion is a plate having a thickness in a third thickness direction intersecting the first thickness direction and the second thickness direction and vibrates in the third thickness direction to configure the path.

Abstract: Primary plate springs overlap a first plate spring segment of a coupling plate spring in a first direction and respectively have a frictional contact portion which generates sliding friction relative to the first plate spring segment in response to vibrations, Secondary plate springs overlap a second plate spring segment of the coupling plate spring in a second direction and respectively have a frictional contact portion which generates sliding friction relative to the second plate spring segment in response to the vibrations while the second direction is different from the first direction. Tertiary plate springs overlap a third plate spring segment of the coupling plate spring in a third direction and respectively have a frictional contact portion which generates sliding friction relative to the third plate spring segment in response to the vibrations while the third direction is different from the first and second directions.
