Abstract
An active anti-vibration deviceincludes a pair of elastic connecting partsand, a rod bodythat connects the pair of elastic connecting parts, an inertial massthat is supported by the rod body, a drive partthat reciprocates the inertial mass in an axial direction of the rod body, and a controllerthat is configured to be able to perform acceleration feedback control to control the drive part so that a first force proportional to an axial acceleration of the rod body is generated.
