Abstract: A vibration isolator configured to restrict vibration generated in a vibration source from being transmitted to a vibration transmitted portion includes at least one elastic member. The vibration transmitted portion is provided with at least one support portion to support the vibration source via the at least one elastic member. The at least one elastic member is disposed between the vibration source and at least the one support portion, and is elastically deformed to suppress the transmission of vibration of the vibration source to the vibration transmitted portion from the at least one support portion. The vibration source and at least the one elastic member are configured so that resonance frequencies in plural vibration modes generated in the vibration source conform to one predetermined frequency.

Abstract: A vibration-isolating device includes: a vibration source, which generates vibrations; and at least one vibration-isolating rubber which is fixed to the vibration source. The vibration source is supported by at least one support member that is fixed to a transmission-receiving member through the at least one vibration-isolating rubber. The vibration source and the at least one vibration-isolating rubber are configured such that a difference between a maximum value and a minimum value of resonant frequencies of a structure, which includes the vibration source, the at least one vibration-isolating rubber and the at least one support member, is equal to or smaller than 10 Hz when the vibration source is vibrated in six degrees of freedom. The at least one vibration-isolating rubber includes: 100 parts by mass of silicone rubber; and larger than 0 parts by mass and equal to or smaller than 3 parts by mass of carbon nanotubes.

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.
