Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a motorcycle.

(Prior Art) Conventionally, a vehicle body cover is sometimes attached to the exterior of a motorcycle to cover the vehicle body solely for reasons of appearance.

For example, this is the case with scooter-type small motorcycles. In such a motorcycle, the cover is attached to the rear half of the vehicle body so as to straddle the vehicle body from above, and therefore has an open bottom surface.

(Problem to be Solved by the Invention) By the way, motorcycles are equipped with tanks such as fuel tanks and oil tanks, and electrical components such as batteries as accessory parts. is located at the rear of the vehicle body above the rear wheels and housed inside the vehicle body cover.

In addition, in the case of motorcycles in which frames at the rear of the vehicle body are arranged on both left and right sides inside the vehicle body cover, there are large gaps between the frames and the vehicle body cover, and between the frames. You can see the accessory parts from there.

When the lower surface of the body cover is open and the frames are placed on both the left and right sides of the cover as described above, muddy water, pebbles, etc. thrown up from the rear wheels can fly into the inside of the body cover and cause damage to the body cover. There is a risk that the vehicle body and attached parts may get dirty or damaged.

The present invention has been made in view of the above-mentioned circumstances, and its object is to enable a simple structure to protect the vehicle body and accessory parts inside the vehicle body cover from muddy water, pebbles, etc.

(Means for Solving the Problems) That is, the present invention provides a lower cover that covers the incidental parts and the frame from below on the lower surface of the vehicle body cover corresponding to above the rear wheel, and closes the portion of the vehicle body cover that corresponds to the rear wheel. The lower cover has a function as a fender.

(Embodiment) An example of carrying out the present invention will be explained with reference to the drawings regarding a scooter type small motorcycle. In Fig. 1, A is the vehicle body, 1 is the engine, 2 is the front wheel, 3 is the rear wheel, 4 is the steering handle, 5 is the engine, 2 is the front wheel, 3 is the rear wheel, 4 is the steering handle, 5 is a sheet. The front half of the vehicle body A is composed of a head pipe 6 and a main pipe 7 extending rearward and downward from the head pipe 6.
A front wheel 2 is supported via a steering shaft 8 and a front fork 9.

The rear half of the vehicle body A is comprised of a backstay 10 that branches into two from the rear of the main pipe 7 and extends rearward, and a planar U-shaped frame member 11 connected to the rear of the backstay 10.

The engine 1 is located at the front rear side of the backstay 10.
A power unit a consisting of a case 12 housing a power transmission mechanism for transmitting the power of the engine 1 to the rear wheels 3 is pivoted so as to be movable up and down, and a seat 5 is attached and supported above the middle part of the backstay 10. has been done.

On the other hand, the frame member 11 holds a fuel tank 13, which is an accessory part, between both sides thereof, and a rear fender 14 is attached to the rear part thereof.

The front part of the fuel tank 13 has a backstay 10.
It is located inside the rear part of the seat 5 and located below the rear part of the seat 5, and its bottom part protrudes below the frame member 11 and corresponds to the upper part of the rear wheel 3.

Each of the constituent members 6, 7, 10, and 11 of the vehicle body A having the above structure is covered with a vehicle body cover b made of synthetic resin.

Body cover b on the rear half of car body A is backstay 1
an upper cover 15 that covers the rear half of the frame member 11 and a footrest cover 1 that is formed of the same body as the footrest plate 16 and is joined to the lower end of the upper cover 15;
7, and a front cover 18 that is joined to both covers 15, 17 and covers the open front and upper surfaces of both covers 15, 17.

The cover 15 has its entire lower surface open, extends over the backstay 10 and the frame member 11 from above, and accommodates the fuel tank 13 inside.

The upper surface of the upper cover 15 is opened at the front half and wraps around from the rear to the front of the bottom of the seat 5, and is screwed to the backstay 10 on both sides of the lower part.

In such a vehicle body cover b for the rear half of the vehicle body A, the lower surface of the upper cover 15 corresponding to the upper part of the rear wheel 3 is covered with a lower cover 19 made of synthetic resin.

The lower cover 19 has a shape along the lower edge of the upper cover 15 as shown in FIGS. 3 and 4, and a bottom plate 19a in the rear half thereof forms a curved surface along the rear wheel 3 and bulges upward. There is.

The bottom plate 19a is located directly above the rear wheel 3 and functions as a fender, and the bottom of the fuel tank 13 adjacent to the upper side of the bottom plate 19a is located directly above the rear wheel 3.
It is said to have a shape that follows. The lower cover 19 is attached and fixed to the upper cover 15 by inserting an elastically deformable locking protrusion 20 provided on its upper edge into a locking hole 21 in the lower part of the upper cover 15. 22 is a mud guard inserted into the front inside of the lower cover 19, and this mud guard 22
This prevents dirty water and the like from entering into the upper cover 15 from the open front lower surface of the lower cover 19.

Therefore, the lower cover 19 and the upper cover 1
5 is covered, the upper cover 15
A portion corresponding to the rear wheel 3 has a closed cross section, and incidental parts such as the frame member 11 and the fuel tank 13 can be housed inside this closed cross section.
As a result, muddy water, pebbles, etc. thrown up from the rear wheels 3 are blocked by the lower cover 19,
The backstay 1 passes upward from between the frame member 11 and the upper cover 15 and is inside the upper cover 15.
0, the problem of damage to the frame member 11, fuel tank 13, etc. can be solved, and the upper cover 15
A large storage space can be easily secured inside.

As explained above, the present invention provides a simple structure in which a lower cover is provided on the lower surface of the vehicle body cover corresponding to the upper part of the rear wheel and covers the incidental parts and the frame from below, and the portion of the vehicle body cover corresponding to the rear wheel is a substantially closed cross section. The structure is such that the lower surface of the vehicle body cover can be immediately covered by the lower cover, and the vehicle body and attached parts inside the vehicle body cover are reliably protected by blocking muddy water, pebbles, etc. thrown up from the rear wheels. I can do it.

Furthermore, the substantially closed cross section is constructed by covering the four sides of the vehicle body cover with the lower cover, and the two frames are arranged and housed on the left and right sides of the substantially closed cross section. In addition to being lightweight, a large storage space can be obtained inside, which can be effectively used as a storage section for accessory parts.
