A vehicle vibration reduction apparatus ( 1 ) includes: an inertial mass body ( 30 ) that is connected to a rotary shaft ( 13 ) of a power transmission apparatus ( 5 ) such that the inertial mass body ( 30 ) is capable of transmitting power, wherein the rotary shaft ( 13 ) of a power transmission apparatus ( 5 ) is capable of transmitting rotary power from a travel drive source ( 4 ) to a drive wheel ( 10 ) of a vehicle ( 2 ); and a switching apparatus ( 40 ) that is provided on a power transmission path between the rotary shaft ( 13 ) and the inertial mass body ( 30 ) and that is capable of switching between a first path ( 42 ) on which the rotary shaft ( 13 ) and the inertial mass body ( 30 ) are connected to each other via an elastic body ( 41 ), and a second path ( 43 ) on which the rotary shaft ( 13 ) and the inertial mass body ( 30 ) are connected to each other without passing through the elastic body ( 41 ). Thus, the vehicle vibration reduction apparatus ( 1 ) can reduce vibration appropriately.
