DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holding structure for a motorcycle.

[0002]

2. Description of the Related Art Generally available motorcycles include:
A battery for power supply is mounted. This battery is
In many cases, it is arranged below a seat that can be opened and closed. A battery holder 100 as shown in FIG. 5 is provided below the seat, and a battery is inserted into the battery holder 100 from above and fixed with a rubber band 101 or the like.

[0003] The battery holder 100 is made of a steel plate or a resin material, and is fastened to a vehicle body frame of a motorcycle by bolts 102 or the like.

[0004]

However, by providing such a battery holder 100, the number of components of the vehicle body is increased and the battery holder 10 is provided.
Since the operation of fixing the O. 0 to the vehicle body frame (the operation of fastening the bolt 102) is required separately, there is a problem that the manufacturing cost of the vehicle body increases.

The battery holder 100 is usually provided with a space between the air cleaner of the engine and the rear fender. However, in order to install the battery holder 100 which is one size larger than the battery, the battery holder 100 is not connected to the air cleaner and the rear fender. It is necessary to greatly increase the distance back and forth,
Inevitably, the capacity of the air cleaner was sacrificed, and the rear fender retreated and the wheelbase became longer.

Therefore, a battery holder 100 was omitted by integrally forming a tray-like battery holding portion capable of storing a battery at the front of a rear fender made of resin or the like (Japanese Patent Application No. 60-109900). Reference). However, in this case, the rear fender has a remarkably complicated shape, which makes it extremely difficult to mold the resin and increases the defective product occurrence rate.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has the advantages of reducing the manufacturing cost of a vehicle body by eliminating the need for a battery holder, while increasing the capacity of an air cleaner and shortening the wheelbase. An object of the present invention is to provide a motorcycle battery holding structure that can be provided.

Another object of the present invention is to make it possible to omit a battery holder without complicating the shape of resin molded parts such as an air cleaner and a rear fender.

[0009]

In order to achieve the above object, a battery holding structure for a motorcycle according to the present invention is provided in a motorcycle in which a battery is held below a seat. An air cleaner is disposed, a rear fender is disposed below the seat and adjacent to the rear side of the air cleaner, and a substantially horizontal battery bottom holding surface is provided at a front portion of the rear fender and a vertically upward direction from a rear end of the battery bottom holding surface. And a battery holding portion extending to the vehicle width direction on both sides in the vehicle width direction and the vehicle body front and upwards, and the rear surface of the air cleaner is flattened so as to be parallel to the battery holding portion of the holding shelf. The battery front holding surface is formed to form a pair of left and right battery side holding arms extending rearward from both sides of the battery front holding surface. A battery holding section is formed from the battery front holding surface and the battery side holding arm, and the holding section of the rear fender and the holding section of the air cleaner are combined to form a bottom, rear, front, and both sides of the battery. And a bottomed box-shaped battery holding portion capable of holding the battery, and a contact portion for contacting an upper portion of the battery held by the battery holding portion is provided below the seating seat.

[0010]

When the battery holding structure of the motorcycle is constructed as described above, the air cleaner and the rear fender disposed below the seating seat function as they are as the battery holder, so that the dedicated battery holder conventionally used can be omitted. As a result, the work of fixing the battery holder is not required, and the manufacturing cost of the vehicle body can be reduced.

Further, since the battery holding portion is provided adjacent to the air cleaner and the rear fender arranged along the front-rear direction of the vehicle body, the air cleaner, the battery and the rear fender can be arranged without a gap. As a result, it is possible to extend the air cleaner rearward to increase the capacity, or to shorten the front-rear distance between the air cleaner and the rear fender to shorten the wheelbase of the motorcycle.

In addition, the battery holding part comprises a holding shelf provided on the rear fender and a holding part provided on the air cleaner. The holding shelf has a battery bottom holding surface and a battery rear holding surface, and has both sides in the vehicle width direction. While it is formed in a simple shelf shape open to the front and upward of the car body,
Since the holding part has a simple shape in which a pair of left and right battery side holding arms protrude from a flat battery front holding surface, the shape of resin molded parts such as air cleaner and rear fender does not become complicated. In addition, since no recess is formed in the air cleaner, a large capacity of the air cleaner can be secured.
