A motorcycle has a fuel tank attached to the front upper part of the vehicle body to store fuel. When a motorcycle runs, the fuel in the fuel tank moves forward and backward due to inertia caused by acceleration and deceleration. Furthermore, when the motorcycle travels on a curved road, centrifugal force causes the fuel in the fuel tank to move left and right. On the other hand, the fuel tank is equipped with an air breather at the top of the fuel filler cap, etc., to allow air to be absorbed from the outside and prevent air lock. However, if the fuel moves too quickly, the fuel may enter the air breather, causing problems. Japanese Utility Model Publication No. 174389/1989 discloses a system in which a partition plate is provided to prevent the fuel in the fuel tank from moving in the front-back direction, but preventing movement in the back-and-forth direction alone is not sufficient.

In view of this, this invention has been developed to prevent fuel from leaking from the air breather in a motorcycle fuel tank by installing an anti-ripple plate in the fuel tank that can reduce the movement of fuel in the front and back directions and the movement in the left and right directions. The purpose is to obtain.
以下、本考案を図面に示す実施例によつて説明

The present invention will be explained below with reference to embodiments shown in the drawings.

あり、前端は開放７してある。そして、後側に、
前後に複数の筒形部８が形成してある。波立防止
板６は、燃料タンク１内に上方に向けて突出させ
て、底板９に溶着する。 The fuel tank 1 is provided with a fuel cylinder 2 projecting downward from its upper surface, and the upper end of the fuel cylinder 2 is closed with a cap 3. And cap 3
, an air breather 4 is provided, and a hose 5
are connected and extended to a high position on the vehicle body. The ripple prevention plate 6 is formed by press-forming left and right steel plates and welding them together. The ripple prevention plate 6 has a front part that surrounds the oil supply cylinder 2, and has a front part that surrounds the oil supply cylinder 2.
The lower part of the ripple prevention plate 6 is overlapped with the upper part of the ripple prevention plate 6, and the front end is left open 7. And on the rear side,
A plurality of cylindrical portions 8 are formed at the front and rear. The ripple prevention plate 6 is made to protrude upward into the fuel tank 1 and is welded to the bottom plate 9.

エアーブリザー４に燃料が流入するのを防ぐこと
ができる。 Therefore, the ripple prevention plate 6 attenuates the movement of fuel in the portion surrounding the fuel supply cylinder 2 and the plurality of cylindrical portions 8 on the rear side, and the centrifugal force during speed changes and curves causes the fuel to flow forward, backward, left and right. Move less.
The ripple prevention plate 6 surrounds the lower part of the fuel supply tube 2 and can particularly prevent fuel from flowing into the fuel supply tube 2. Therefore, fuel can be prevented from flowing into the air breather 4 located above the fuel supply cylinder 2.
以上説明したように、この考案は、前部を開放

きる。
As explained above, this invention has an open front part that forms a wall surrounding the fuel tank, and a ripple prevention plate with multiple cylindrical parts on the rear side that is erected inside the fuel tank. Since the upper part of the ripple prevention plate is overlapped on the outside, the uneven shape of the ripple prevention plate can attenuate the movement of fuel and reduce the movement of fuel in the front and back and left and right directions. Since the lower part of the fuel supply cylinder is surrounded by the ripple prevention plate, it is possible to prevent fuel from flowing into the fuel supply cylinder, and it is also possible to prevent fuel from entering the air breather provided at the top of the fuel supply cylinder. The ripple prevention plate can be easily manufactured by simply welding it to the bottom plate and then aligning and welding the top of the fuel tank to the bottom plate.
