Claim:
1. An active vibration isolating support apparatus for reducing vibration transmitted from an engine provided with a crank pulse sensor, wherein the engine in which a reciprocating motion of a piston is converted to a rotary motion of a crankshaft is supported via vibration isolating support units in a vehicle body each of which comprises an actuator, the active vibration isolating support apparatus comprising: a control unit connected to the actuator and configured to drive the actuator to extend and contract periodically depending on a vibrational state of the engine, thereby reducing transmission of vibration of the engine to the vehicle body, wherein the vibration isolating support units are disposed on opposite sides of the crankshaft, and and wherein 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 positioned on a side where the one is to be compressed by roll vibration associated with an initial explosion, so as to reduce transmission of roll vibration of the engine in a direction which is reverse to the rotation direction of the crankshaft of the engine when the initial explosion is determined to be detected by the control unit using crank pulse intervals output from the crank pulse sensor after a time when the engine starts at a time of starting of the engine.
