Publication number: 20120222929Abstract: An automobile vibration damping device for an automobile in which a power plant in which an engine, a transmission and the like are combined is supported by a vehicle body, including a vibrating means that generates vibration separate from vibration of the engine. Thereby, it is possible to reduce the vibration amplitude of a seat portion by the reaction force of the vibrating means. Also, if the vibration mode of the vehicle body is adjusted so as to become a node in the vicinity of the seat portion, the vibration amplitude decreases in the vicinity of the seat portion, and improves riding comfort.Type: ApplicationFiled: May 11, 2012Publication date: September 6, 2012Applicant: SINFONIA TECHNOLOGY CO., LTD.Inventors: Yasushi MURAGISHI, Takayoshi FUJII, Takashi FUKUNAGA, Hideaki MORIYA, Katsuyoshi NAKANO, Hiroshi NAKAGAWA, Takashi ONOUE, Yushi SATO
