An obstacle device for vehicle driving experience has a support arm (3) placed outside the course (P) of a vehicle (V), a support rod (4) supported by the support arm (3) and capable of rocking backward and forward along the course (P), and an obstacle (5) attached to the tip of the support rod (4) and placed within the course (P) of the vehicle (V). Between the support arm (3) and the support rod (4) is provided rocking control means (30). The rocking control means (30) makes the resistance of backward rocking of the support rod (4) from its forward rocked position to be greater than the resistance of forward rocking of the support rod (4) caused by a collision of the vehicle (V) to the obstacle (5). Thus, in vehicle driving experience, an impact of a collision of the vehicle to the obstacle can be effectively eased and, after the collision, the obstacle can be easily and quickly placed at a home position.
