Claim Text:
1. A vehicle vibration reduction apparatus comprising: an inertial mass body that is connected to a rotary shaft of a power transmission apparatus such that the inertial mass body is capable of power transmission, wherein the power transmission apparatus is capable of transmitting rotary power from a travel drive source to a drive wheel of a vehicle, the inertial mass body being provided parallel to a power transmission path of the power transmission apparatus extending from the travel drive source to the drive wheel; and a switching apparatus that is provided on the power transmission path between the rotary shaft and the inertial mass body and that is capable of switching between a first path on which the rotary shaft and the inertial mass body are connected to each other via an elastic body, and a second path on which the rotary shaft and the inertial mass body are connected to each other without passing through the elastic body.
