A vibration reduction apparatus according to the present invention includes: an actuator apply a force to a beam supporting a cabin so as to bend the beam; an acceleration sensor measuring the acceleration of the cabin; and a controller controlling the actuator based on the measured acceleration. When a vibration containing a plurality of vibration components is transmitted to the cabin via the beam, the vibration reduction apparatus thus structured can achieve the vibration reduction more certainly by applying a bending load to the beam so that the bending load caused by the vibration is cancelled; this allows providing damping of the cabin more certainly.
