PROBLEM TO BE SOLVED: To provide an active vibration control device and an engine mount control device which can favorably suppress engine vibration in the re-start of an engine.SOLUTION: In an air pipe 212 of an active vibration control device 200, a one-way valve 216 is provided between a negative pressure source 210 and a control valve 214. The one-way valve 216 permits inflow of air from an engine mount 202 side toward a negative pressure source 210 side, and blocks inflow of air from the negative pressure source 210 side toward the engine mount 202 side. 【課題】エンジン再始動時のエンジン振動を好適に抑制することが可能な能動型防振装置及びエンジンマウント制御装置を提供する。【解決手段】能動型防振装置２００の空気管２１２には、負圧源２１０と制御弁２１４との間においてワンウェイバルブ２１６が設けられる。ワンウェイバルブ２１６は、エンジンマウント２０２側から負圧源２１０側に向けての空気の流入を許容し、負圧源２１０側からエンジンマウント２０２側に向けての空気の流入を遮蔽する。【選択図】図２
