PROBLEM TO BE SOLVED: To make compatible both the securement of responsiveness to an acceleration demand from a driver and the improvement of fuel economy. SOLUTION: The vehicle includes an operation member 8 for an input of an acceleration or deceleration demand by varying an operation position, a throttle valve 22 for adjusting an intake air amount of an engine 12, and a control device 19 drivingly controlling the throttle valve 22 based on the operation position of the operation member 8. The control device 19 includes an opening degree setting part 45 setting a target opening degree of the throttle valve 22 based on the operation position of the operation member 8, and an acceleration determination part 47 determining the magnitude of an acceleration demand while the acceleration demand is inputted in the operation member 8. The opening degree setting part 45 sets the target opening degree with a change rate of the target opening degree agreed with a first opening degree following a change rate of the operation member while the acceleration demand is determined to be large by the acceleration determination part 47 and sets the target opening degree with the change rate of the target opening degree agreed with a second change rate smaller than the first change rate while the acceleration demand is determined to be small.
