Description

[Detailed Description of the Invention] In ordinary motorcycles, since the rear fender is integrally attached to the vehicle body frame,
When removing the rear tire, it was necessary to first move the tire slightly rearward and then move it downward.

In this case, in a place where the rear tire is located with a concave lower part, the above-mentioned rear tire removal or installation work can be carried out relatively easily and efficiently, but in a normal place, the car body is lifted and the car body is lifted up. It was extremely difficult to remove and install the rear tire within a short period of time.

In particular, as shown in Fig. 1, in a motorcycle in which the rear fender a extends downward longer than the rear tire b, and in a motorcycle in which side bags or the like are installed on both sides of the rear tire b, the vehicle body can be moved to either the left or right side. If you do not tilt the rear fender a diagonally or remove the rear fender a from the vehicle body, the rear tire b will hit the shaded area _a1 of the rear fender a, as shown in Figure 1, making it extremely difficult to attach and remove the rear tire b. It is difficult, and moreover, the rear fender a
It took a lot of effort to remove the rear tire b, and it was not possible to efficiently remove the rear tire b within a short period of time.

The present invention relates to an improvement of a rear fender for a motorcycle that overcomes these difficulties, and its purpose is to make it possible to easily remove and install a rear tire regardless of the location, even on a motorcycle with a long rear fender. The purpose of the present invention is to provide a rear fender for a motorcycle.

An embodiment of the present invention shown in FIGS. 2 and 3 will be described below. Reference numeral 1 denotes a fender body fixedly attached to the vehicle body side (not shown);
The center part in the width direction of the lower end 1a of the fender body 1 is located above the height of the tire top surface x-x at the time of tire replacement, and the lower end 1a of the fender body 1 is subjected to step drawing processing inward, and the lower end of the fender body 1 is The fender piece 2 is formed so that it can be separated and joined to the step portion 1a, and the rear fender is constituted by the fender main body 1 made of steel and the fender piece 2 made of synthetic resin such as polyethylene or polypropylene.
They may also be of other suitable materials.

Further, a tail light bracket 3 is removably attached to the fender main body 1 with bolts and nuts 5, 6, and a tail light 4 is removably attached to the tail light bracket 3.

Furthermore, pin 7 is attached to tail light bracket 3.
is penetrated and locked with the stop pin 8, and the same pin 7
The upper end sleeve portion 10a of the license plate holder 10 is fitted through a nylon bush 9 so as to be vertically movable. Note that 11 is a washer.

Furthermore, nails 12 are placed on both sides of the back side of the license plate holder 10 along the top and bottom surfaces perpendicular to this.
A grommet 13 made of elastic material such as rubber is fitted into the hole 3a of the taillight bracket 3 facing the nail 12, and the license plate holder 10 is shown as a solid line in FIG. When the nail 12 integrated with the license plate holder 10 is in the normal downward setting position as shown in the figure, the nail 12 is attached to the grommet 13.
The friction force acting between the nail 12 and the grommet 13 causes the license plate holder 1 to
0 is now able to firmly hold its position.

Furthermore, the stay 1 is attached to the upper part of the outer surface of the fender piece 2.
4 protrudes rearward, and a mounting bracket 15 is integrally fixed to the lower back surface of the license plate holder 10, and the license plate holder 10 is suspended in the normal downward setting position, and the mounting bracket 15 is fixed with bolts 16 and nuts 17. When the stay 14 is integrally attached to the fender body 1, the upper end edge of the fender piece 2
It is designed to be fitted into a without any gaps.

Reference numeral 18 denotes a rear tire. When the rear wheel (not shown) with the rear tire 18 mounted thereon is properly mounted on the rear fork (not shown), the outer peripheral surface of the rear tire 18 is at the position shown by the solid line, and the tire cannot be replaced. At this time, the upper end of the outer circumferential surface of the rear tire 18 is at the position indicated by the double-dashed chain line.

Since the embodiment shown in FIGS. 2 and 3 is constructed as described above, when a force is applied diagonally upward to the license plate holder 10 when the tire 18 is to be replaced, the nail 12 is moved against the grommet 13. The license plate holder 10 and the fender piece 2 are separated from each other with the pin 7 as the center.
is swung diagonally upward as shown by the two-dot chain line.

Therefore, even if the upper end position of the outer peripheral surface of the rear tire 18 at the time of tire replacement is x-x, the fender piece 2, which is the lower part of the rear fender, can be positioned above this x-x height, and the rear tire 18
The removal and installation work can be easily done within a short time.

After changing the tire, lower the license plate holder 10 and attach the nail 12 to the grommet 13.
When inserted, the license plate holder 10 can be returned to the desired setting position, and the upper end of the fender piece 2 of the rear fender can be joined to the lower end step 1a of the fender main body.

Moreover, since it is only necessary to fit and remove the nail 12 of the license plate holder 10 into the grommet 13, the fender piece 2 can be easily attached and detached within a short time.

Furthermore, since the mounting bracket 15 is integrally formed below the back surface of the license plate 10, an increase in the number of parts can be suppressed as much as possible and the structure can be simplified.

In the embodiment shown in FIGS. 2 and 3, the nail 12 is fitted into the grommet 13 and the fender piece 2 is set in the extending direction of the fender main body 1. Instead of frictionally holding the license plate 8, the license plate 8 may be fixed using a wedge, a cotter pin, or a screw.

As described above, the present invention has a fender piece that is separable from the fender main body fixed to the vehicle body and is swingably pivoted to a fixing means such as a tail light bracket via a mounting bracket. By swinging the fender piece upwardly with respect to the fixing means via the mounting bracket, even if the lower end of the temporary rear fender extends downward for a long time, the motorcycle body will not be lifted or tilted upward. Easily remove the rear tire,
It can be installed and rear tires can be replaced efficiently within a short period of time.

Further, in the present invention, a tail light bracket is integrally fixed to the rear part of the fender main body fixed to the vehicle body side, and a mounting bracket is pivotally attached to the tail light bracket so as to be swingable about the width direction of the vehicle, and the fender main body is attached to the fender main body. Since the fender piece that can be connected to and separated from the rear fender piece is integrally fixed to the mounting bracket, and the license plate holder portion is integrally formed on the mounting bracket, the taillight is fixed to the vehicle body side completely regardless of the swinging of the rear fender piece. Since the swinging weight is reduced and the force necessary to fix the rear part of the rear fender is reduced, a small and simple fixing means is sufficient.

Furthermore, in the present invention, the fender piece is swingably mounted using the tail light bracket for mounting the tail light and the mounting bracket for mounting the license plate, thereby reducing the number of parts, resulting in cost reduction, weight reduction, and space efficiency. It is possible to improve the

Furthermore, in the present invention, the tail light remains fixed regardless of the swinging of the rear part of the rear fender, making wiring easier.
