Beschreibung
Zusammenfassung:	An active vibration isolating support apparatus reduces vibration transmitted from a reciprocating engine. The apparatus supports the engine via vibration isolating support units each of which includes an actuator. The vibration isolating units are disposed on opposite sides of a crankshaft of the engine. The apparatus includes a control unit to make the actuator extend and contract periodically depending on a vibrational state of the engine so as to reduce the transmission of engine vibrations to a vehicle body. The control unit drives the actuator of one of the vibration isolating support units to contract, the one of the vibration isolating support units being compressed by roll vibration associated with an initial explosion after a time when the engine starts, so as to reduce transmission of roll vibration in a direction which is reverse to the rotation direction of the crankshaft.
