Excitation device for inspection of a vehicle

An excitation device exciting a vehicle by applying a vibration to at least one of a plurality of tires of the vehicle, comprising:

• a first restricting part arranged in one of a front and rear direction of the at least one of the plurality of tires to restrict movement of the vehicle in the front and rear direction;
• a second restricting part arranged in another of the front and rear direction of the at least one of the plurality of tires to restrict movement of the vehicle in the front and rear direction;
• an actuator configured to drive at least one of the first restricting part and the second restricting part to increase or decrease a distance between each other in the front and rear direction of the vehicle;
• and
• the memory stores vibration data of the vehicle against a time axis expected based on a traveling speed, acceleration and deceleration when the vehicle travels a predetermined course, and
• the CPU is configured to perform
• controlling the actuator according to the vibration data to drive at least one of the first restricting part and the second restricting part to increase or decrease the distance between each other in the front and rear direction of the vehicle.
