2. Description of the Related Art Motorcycles in which parts and the rider's body are exposed have a large air resistance, and when running at high speeds, the rider is liable to fatigue due to wind pressure. A cover that covers the motorcycle and the rider to allow the wind to escape to the outside of the motorcycle is called cowl or cowling.

[0003] The cowling originally covers a motorcycle for a racer to improve the air flow and reduce the air resistance. However, today, due to its effect and fashion, motorcycles for running on public roads such as sports motorcycles. Was also equipped. It should be noted that the cowling used for motorcycles for traveling on public roads is generally referred to as fairing, but in this specification, the vehicle body is covered without distinguishing between those used for public roads and those used for racing. The term cowling is used as a generic term for things.

As described above, there are various types of cowlings, which need to reduce the air resistance received by the rider while traveling to enhance the windproof effect, and have different locations for covering the vehicle body. For example, there are an upper cowl that covers the periphery of the headlamp and an under cowl that covers a range from the front to the side of the engine.
