The invention provides an active vibration-proof device which can properly inhibit the engine vibration when an engine is restarted, and an engine frame control device. A one-way valve (216) is arranged between a negative pressure source (210) and a control valve (214) on the air pipe (212) of the active vibration-proof device (200). The one-way valve (216) allows air to flow in a direction from the engine frame (202) to the negative pressure source (210) and inhibits the air from flowing from the negative pressure source (210) to the engine frame (202).
