To provide a vehicle allowing a driver to prevent a vehicle body from tilting sharply and improve riding quality.

In this vehicle, the center of gravity is moved forward by moving a riding part 13 forward to cope with rapid acceleration because there are many high frequency components (sudden change) at rapid acceleration time {see Fig. 16 (a)}. After that, the riding part 13 is moved backward (in the direction of original reference position) by tilting the riding part 13 gradually {see Fig. 16 (b)}. Consequently, it is possible to prevent the vehicle from tilting sharply by moving the riding part 13 and moving the center of gravity at the moment of rapid acceleration (high frequency component part), and then the vehicle body is slowly tilted (low frequency component part) to improve riding quality.
