Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for mounting a battery storage box in a motorcycle equipped with a so-called front-rear V-type engine in which the crankshaft is disposed in the width direction of the vehicle body.

2. Description of the Related Art Conventionally, there have been motorcycles in which a so-called front-rear V-type engine with a crankshaft disposed in the width direction of the vehicle body is mounted near the center of the vehicle body. Conventional vehicles of this type usually have a battery storage box that houses the batteries fixed to the vehicle body, and are configured so that only the batteries can be taken in and out. However, if this battery is placed near the engine, especially below the driver's seat, the rear cylinder of the engine and the battery storage box will be close together, resulting in a problem that the maintainability of the engine, especially the rear cylinder, will be significantly impaired. It was hot. For example, if the exhaust pipe is connected to the rear surface of the rear cylinder, the ease of attaching and removing the exhaust pipe becomes difficult, and in the case of a four-stroke engine, the maintainability of the valve mechanism, spark plug, etc. becomes difficult.

Furthermore, when the exhaust pipe is disposed behind the rear cylinder, there is a problem in that it is difficult to fit tools etc. there, and if the battery storage box is disposed here, the workability of fixing it becomes extremely poor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the maintainability of the engine, especially around the rear cylinder, and to make it extremely easy to fix the battery storage box when a front and rear V-type engine is installed. The purpose of the present invention is to provide a mounting structure for a battery storage box for a motorcycle that allows for the mounting of a battery storage box for a motorcycle.

According to the present invention, this purpose is achieved by placing a
In a motorcycle in which at least the rear cylinder of a V-type engine is located in which the crankshaft is disposed in the width direction of the vehicle body, the pair of left and right frames have a mounting portion for a battery storage box located at the rear of the rear cylinder divided into left and right parts. The battery storage box is removably held upward in these mounting parts, while the bottom of the storage compartment provided on the side of the driver's seat that can be opened and closed is brought into contact with the top surface of the batteries housed in the battery storage box. This is achieved by a mounting structure for a motorcycle battery storage box characterized by the following. That is, the width of the battery generally has a dimensional relationship suitable for the present invention with the spacing between the left and right frames, and this takes advantage of the fact that when the battery is removed, a sufficiently large space is formed between the left and right attachment parts. In addition, while the battery storage box can be attached and removed up and down, the battery is held down by the bottom of the storage compartment on the seat side, so the battery storage box can be easily installed and removed without putting any tools behind the rear cylinder.

The present invention will be explained in detail below based on the drawings.
