いようにしたものである。[Detailed description of the invention] This invention relates to a fender device for a motorcycle (particularly a motorcycle with a mono-suspension mechanism). Also, by providing a wall part (chain guide wall part) that separates the chain from other parts, which is integrated with the fender, the chain does not damage other parts. .

た。 In a motorcycle, the pivot point of the swing arm that supports the rear wheel to the vehicle body frame is behind the rotation center of the drive sprocket that hangs on the front of the rear wheel drive chain, and there is a distance difference between them. Therefore, when the swing arm swings vertically while the vehicle is running, the rear wheel drive chain (hereinafter referred to as the chain) becomes slack, causing the chain to swing. This is particularly severe in motorcycles with mono-suspension mechanisms. When the chain swings, it comes into contact with other parts on the top, bottom, left and right, such as the car body frame and air cleaner.
These may be damaged. In the past, no consideration was given to this problem.
本考案はリヤフエンダーを利用して、この問題

通され、後輪５が支持されている。 The present invention uses a rear fender to solve this problem. An embodiment of the present invention will be explained with reference to the drawings. First, in FIG. 1, 1 is a vehicle body frame, and 2 is a swing arm whose front end is pivotally connected to the lower part of the vehicle body frame 1 by a shaft 3. A shaft 4 is inserted through the rear end of the swing arm 2, and a rear wheel 5 is supported.

７で結合されている。 A central portion of a bell crank 6 is pivotally attached to the intermediate portion of the frame pipe 1 via a shaft 7, and a cushion unit 8 is disposed between the front end of the bell crank 6 and a portion near the front end of the swing arm 2. are interposed by shafts 9 and 10. A sprocket 11 is integrally attached to the rear wheel 5,
A chain 14 is stretched between this sprocket 11 and a sprocket 13 on the side of the engine 12, so that the rear wheels 5 are driven. A rod 1 is connected between the rear end of the bell crank 6 and the middle part of the swing arm 2 via shafts 15 and 16.
They are joined by 7.

曲面凹部２０を設けたものである。 A part of a rear fender having a shape as described later is attached to the lower part of the body frame 1 where the bell crank 6 is attached, to prevent mud and water splashing from the rear wheel 5 from splashing onto the cushion unit 8 and other parts. I've made sure that it doesn't happen. Figures 2 to 4 show this rear fender according to the present invention. This rear fender 18 is made of synthetic resin and is made of chain 14.
A wall portion 19 having a U-shaped cross section is formed in the portion through which the cushion unit 8 passes, and a curved recess portion 20 surrounding the rear surface of the cushion unit 8 is provided inside the wall portion 19.

１８に当ることがない。 This rear fender 18 configured in this way
is used by being attached to the vehicle body frame 1 as shown in FIG. As a result, chain 14
The front, rear, left and right parts of the chain are separated from other parts (body frame, air cleaner, etc.) by walls 19 (see Figure 6), so even if the chain 14 swings up, down, left or right, this will prevent the chain guide from acting. This prevents the above-mentioned other parts from being hit.
Also, even if the cushion unit moves due to the vertical swing of the swing arm 2, the rear fender 1
The curved recess 20 of 8 prevents this from hitting the rear fender 18.

る。 Since the present invention is constructed as described above, although it has a simple construction, it has the effect of reliably preventing the influence of chain vibrations on other parts. In addition, it is possible to prevent the rear fender from coming into contact with the cushion unit that moves with the swinging of the swing arm.Furthermore, if the rear fender is made of synthetic resin as in the example, parts costs can be reduced. This also has the advantage of reducing assembly costs.
