Abstract
Described is a vibration isolator of a vibration actively reducing apparatus which achieves a more accurate detection of a residual vibration by means of a load sensor after an interference of a controlled vibration developed from a controlled vibration source constituting the vibration isolator against a vibration developed and transmitted from a vibration source such as a vehicular engine. In the vibration isolator, all vibration forces developed and transmitted from the vibration source are once concentrated onto a predetermined rigidity member such as a yoke of an electromagnetic actuator constituting the controlled vibration source and the load sensor is installed between the predetermined rigidity member and a lid member of the vibration isolator coupled to a supporting base member attached onto, for example, a vehicle body.
