Embodiment Construction
[0025] Hereinafter, an embodiment will be described based on the drawings. figure 1 It is a left side view of the motorcycle of this embodiment. An air-cooled engine 3 is disposed between the front wheels 1 and the rear wheels 2. The air-cooled engine 3 includes a crankcase 4 and a forward-inclined cylinder 5 protruding upward from the front portion thereof. Air is inhaled from the rear of the cylinder 5 through the carburetor 6 and the air filter 7, and discharged from the exhaust pipe 8 to the rear muffler 9. The exhaust pipe 8 extends obliquely downward from the front of the cylinder 5 and passes through the lower part of the vehicle body to the rear extend.
[0026] The body frame supporting the air-cooled engine 3 is provided with: a main frame 11 extending from the head pipe 10 obliquely behind the air-cooled engine 3; The middle frame 13 is bent downward from the rear end of the main frame 11, extends downward in the rear direction of the air-cooled engine 3, and supp...

The invention provides an air guide structure of a motorcycle. Running air is divided into air towards a driver and air for cooling an engine in a simple structure by a shield. An outer shield (100) and an inner shield (200) form a shield (22) for covering each front lateral surface of a fuel tank (20) and a cylinder (5). The inner shield (200) is provided with a first air guide part (210) on theupper part and a second air guide part (240) on the lower part, and each air guide part receives the running air. The running air is received in a first ventilation passage between the outer shield (100) and the inner shield (200) from a first air guide port (210) by the first air guide part (210), is bent towards the oblique upper part to flow to the rear part, flows out of the rear part from anexhaust outlet, and faces a driver seat (21a) through the lateral surface of the fuel tank (20). The lower part of the shield (22) is provided with a second ventilation passage which bends the running air received to the second air guide passage from an air guide port (242) of a second ventilation part (24) to the oblique rear part and the lower part, and the running air flows to the lateral surface of the cylinder (5) of an air-cooled engine to perform cooling.
Description
technical field [0001] The present invention relates to an air guide structure of a motorcycle realized by a shroud covering the side of a fuel tank, and more particularly relates to an air guide structure capable of guiding traveling wind to both a driver and an engine. Background technique [0002] In a shroud structure that covers a part of the side of a fuel tank, a grill opening penetrating inside and outside is provided in a part of the shroud, and a structure in which traveling wind flows rearward through the grill opening is known. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-320427 [0004] In the conventional example described above, the grille opening is formed in the shroud covering a part of the side of the fuel tank. However, this structure only allows the traveling air to flow in a certain direction, and the opening cannot actively control the flow of the traveling air. However, if the traveling wind can be controlled so as to flow toward th...
