Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle article storage structure having an article storage chamber inside a vehicle body frame.

[0002]

2. Description of the Related Art An underbone type vehicle body frame is provided in which a space between a front head portion and a rear half portion of the vehicle body frame is lowered downward in order to allow a passenger to easily get on and off the vehicle body frame. There are motorcycles.

In many cases, such a motorcycle is provided with a large-capacity article storage chamber below a seating seat for storing a large article such as a helmet. In this case, articles are taken in and out by opening and closing the seat.

[0004]

By the way, when the helmet is stored in the article storage chamber, the article storage chamber becomes almost full, and there is almost no surplus space for storing other small articles. Therefore, there may be a case where a second article storage chamber that can store other small articles is provided. The second article storage chamber is preferably formed by providing an openable / closable storage container in the underbone portion so that articles can be easily taken in and out.

However, the height of the underbone portion cannot be increased so much that the passenger can easily get on and off the vehicle so as to easily cross the vehicle body frame. As a result of the bottom of the storage container protruding further downward, the side and bottom of the storage container may collide with a step or an obstacle on the road surface and be damaged due to the bottom of the storage container approaching the road surface. In order to avoid such damage, the bottom of the storage container should be sufficiently separated from the road surface, but this will sacrifice the internal capacity of the storage container.

The present invention has been made in order to solve the above-mentioned problems, and even if an article storage chamber having a large internal capacity is provided in a lower underbone portion, a storage container forming the article storage chamber is provided. An object of the present invention is to provide an article storage structure for a motorcycle that is not likely to be damaged and that allows articles to be taken in and out easily.

[0007]

In order to achieve the above object, the article storage structure for a motorcycle according to the present invention is such that the front half of the vehicle body frame is an underbone portion which is inserted downwardly downward and the rear portion of the vehicle body frame. In a motorcycle in which a unit swing type power unit is arranged below, the rear half portion of the underbone portion is composed of a pair of left and right frame members, and footrest brackets extending downward are provided on the left and right frame members. An engine guard that covers the lower surface of the power unit is fixed between the brackets, and a storage container that opens upward is installed in the space surrounded by the engine guard and the left and right footrest brackets, and the upper part of the storage container is fixed to the frame material. In addition, a lid member that can be opened and closed was provided at the opening of the storage container.

[0008]

According to the motorcycle article storage structure having the above structure, the storage container is firmly surrounded by the footrest brackets located on the left and right of the storage container and the engine guard located below the storage container. For this reason, even if a storage container with a large internal capacity is provided in the lower underbone portion, there is no risk of the storage container colliding with a step or an obstacle on the road surface and being damaged.

Further, since the lid member for opening and closing the storage container is located in front of the seat, the occupant of the motorcycle can easily take in and out the article while seated.

Is configured as a main part. Here, the joint portion between the down tube 5 and the frame member 6 is positioned substantially in the middle of the underbone portion 3, and the pair of left and right frame members 6 constitutes the latter half of the underbone portion 3. ing.

The frame member 6 is bent at a substantially central portion of the vehicle body frame 2 and extends obliquely rearward and upward to form the vehicle body frame 2.
The left and right frame members 6 are connected in a U-shape at the rear end. A seat rail 7 extends forward from the vicinity of the rear end of the frame member 6. The seat rail 7 is substantially U-shaped in a plan view, and is fixed to the frame member 6 so that its curved portion side faces forward.

A front fork 9 supporting a front wheel 8 is pivotally mounted on the head pipe 4 together with a handlebar 11, a headlight 12, a front fender 13 and the like so as to be rotatable left and right. A unit swing type power unit 14 is arranged below the rear portion of the vehicle body frame 2.
The front end of the power unit 14 is rotatably connected around a pivot shaft 15 provided in the vehicle width direction at the lower center of the body frame 2, and a rear wheel 16 is pivotally supported at the rear of the power unit 14. A shock absorber 17 is provided between the rear portion of the power unit 14 and the rear portion of the vehicle body frame 2.
Are coupled, and the vertical swing of the power unit 14 and the rear wheel 16 is buffered and restored.

A carburetor 18 and an air cleaner 19 are provided above the power unit 14. A rear fender 21 is attached to the rear part of the body frame 2,
A tail lamp 22 is provided on this. Reference numeral 23 is an exhaust muffler extending from the power unit 14.

A first storage container 24 is installed below the seat rail 7 of the vehicle body frame 2, and a seating seat 25 is placed on the seat rail 7 so as to be openable and closable with a hinge 26 as a fulcrum. The inside of the first storage container 24 is a large-capacity first article storage chamber 28 capable of storing a helmet 27 and the like, and articles are taken in and out by opening the seat 25. In addition, for example, a partition plate 29 is provided inside the first storage container 24, an upper part of the partition plate 29 is the first article storage chamber 28, and a lower part of the partition plate 29 is a liquid tank chamber 31 such as a fuel tank. (See also FIG. 3). in this case,
An injection hole 32 of the liquid tank chamber 31 is provided at the front end of the first storage container 24.

FIG. 3 is a sectional view taken along the line III-III in FIG. As shown in FIGS. 1 to 3, bracket stays 33 are fixed to the left and right frame members 6 forming the latter half of the underbone portion 3, and the footrest brackets 34 and the bolts 35 are fixed to the bracket stays 33.
