ABSTRACT:
A chassis frame for a vehicle such as a motorcycle is provided with an engine mounted at the chassis frame and an engine guard near the engine spaced apart between chassis frame and the engine to protect the engine. The engine guard protrudes toward the chassis frame. An inclined surface is formed inside the chassis side of the engine guard so as to be oppositely faced against the engine, and an air guide passage is formed between the inclined surface and the engine. During operation of the vehicle, the air or wind passes through the air guide passage to enhance the cooling of the engine. The aforementioned arrangement prevents the disturbance or prohibition of the flow of engine cooling air during operation of the motorcycle while also enabling a relatively high degree of freedom in design with respect to an outer appearance of the engine guard and vehicle.
