1. A vibration reducing apparatus for a vehicle, the vehicle having a running power source generating rotational power for causing the vehicle to run, a driving wheel, and a power transmission device transmitting the rotational power to the driving wheel via a damper from the running power source, the vibration reducing apparatus comprising:

  • an inertial mass body that is connected to the running power source or the power transmission device;

    a first engagement device configured to switch between a state where the running power source engages with the damper of the power transmission device so as to enable power transmission between the running power source and the damper and a state where the engagement of the running power source and the damper is released;

    a second engagement device configured to switch between a state where the power transmission device engages with the inertial mass body so as to enable power transmission between the power transmission device and the inertial mass body in a power transmission pass different from that of the first engagement device and a state where the engagement of the power transmission device and the inertial mass body is released; and

    a third engagement device configured to switch between a state where the running power source engages with the inertial mass body so as to enable power transmission between the running power source and the inertial mass body in a power transmission path different from those of the first engagement device and the second engagement device and a state where the engagement of the running power source and the inertial mass body is released.
