Sometimes hits or gets caught on the arm 15f ', a large force acts on the welded portion W of the base by the lever action, and cracks or breakage often occur in the welded portion W. Was. On-site repairs and parts replacement for such cracks and breaks in the welded portion W require a very long hand gap. SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned prior art, and has as its object to provide a bollard device having a bogie having a structure capable of improving durability against collision with an arm of a vehicle that gets on and off a parking pallet, and against catching. And SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vehicle stop device according to the present invention is provided so that a parking pallet can be pivotally moved in a longitudinal direction between a standing position and a falling position on a side portion of the parking pallet. A safety fence provided, driving means for driving the safety fence upside down when a vehicle is moved in and out of the parking pallet, and driving upright when loading and transporting the vehicle on the parking pallet; and the parking pallet. At a front position or a rear position of at least one of a front wheel and a rear wheel of a vehicle mounted thereon, or at a front position and a rear position,
The first spring is urged to the raised position, and the urging force causes the arm to be mounted so as to abut against a part of the safety fence. Wherein the arm is pivotally mounted on the wheelchair via a second spring having a spring force greater than that of the first spring. [0008] Therefore, in the vehicle stop device of the present invention, the safety fence is caused to fall down on the side of the parking pallet in the longitudinal direction of the parking pallet by the driving means so that the vehicle door can be moved in and out of the parking pallet. The vehicle door is opened and the drive means raises the vehicle in the same longitudinal direction to prevent the vehicle door from suddenly opening when the vehicle is transported by the parking pallet, thereby preventing the vehicle from being disturbed. The bollard is urged to a raised position by a first spring at a front position or a rear position, or at a front position and a rear position, of at least one of a front wheel and a rear wheel of a vehicle mounted on a parking pallet. The safety fence is lowered and raised in conjunction with the falling and rising of the safety fence via an arm mounted so as to abut against a part of the safety fence by the force. In other words, this car stop does not require a dedicated driving means for the fall down operation, the fall down of the safety fence when the vehicle is put in and out, the fall down operation is performed so that the tires can be overcome, and the safety fence rises when standing up. Even if the parking pallet is tilted or shaken during the transportation of the vehicle, the vehicle is reliably prevented from shifting and the vehicle is reliably prevented from moving before the conditions for taking the vehicle out of the parking pallet are met. Further, since the arm of the bollard has a flexible structure which is pivotally mounted on the bollard via a second spring having a spring force stronger than that of the first spring, the arm can be prevented from hitting by the vehicle. Even if hooking occurs, the impact at this time can be buffered by the second spring, so that the durability is high. In addition, since the spring force of the second spring for the arm is greater than the spring force of the first spring for the car stop, when the safety fence falls down, the car stop falls down before the arm turns.
