DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of vehicle components in a motorcycle in which a vehicle body frame, a seat, a side cover, an oil reservoir, and the like are used as vehicle components.

[0002]

2. Description of the Related Art Conventionally, there is a structure for arranging vehicle components in a motorcycle as described below.

[0003] That is, a side opening is formed in the side of the body frame to open the inside of the frame of the body frame to the outside, and a side cover is attached to the side of the body frame. The side opening is opened and closed.

On the other hand, a rear wheel brake device is provided, and this device includes a hydraulic cylinder that supplies pressure oil to a brake body such as a brake caliper in response to operation of a brake pedal. An oil sump tank is provided in the frame of the vehicle body frame, and the oil sump tank is detachably fastened to the vehicle body frame side by a fastener. The oil reservoir is connected to the hydraulic cylinder by a flexible tube, and the oil in the oil reservoir is supplied to the hydraulic cylinder through the tube.

In the manufacturing process of the motorcycle, before the side cover is attached to the vehicle body frame, an operation of injecting oil through a side opening into an oil reservoir tank already provided in the frame of the vehicle body frame is performed. . And then,
The side cover is attached, and the side opening is closed.

[0006]

Since the side cover is a flat thin plate and has low rigidity, a large number of fasteners are usually used to attach the side cover to the vehicle body frame.

For this reason, when the user attempts to perform maintenance or inspection such as checking the oil level in the oil reservoir tank after running the motorcycle to some extent, the user tries to remove the side cover as described above. Because there are many fasteners in
There is a problem that the removal is troublesome, and the maintenance and inspection work is complicated.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and in a case where an oil sump tank is provided in a frame of a vehicle body frame, the oil sump tank is supplied to the oil sump tank in a manufacturing process of a motorcycle. An object of the present invention is to make it possible to easily perform an oil filling operation and to easily perform maintenance and inspection work on an oil reservoir tank of a completed vehicle.

Another object of the present invention is to prevent the space for accommodating other components in the frame of the vehicle body frame from being excessively narrowed when the above object is achieved.

An upper opening 45 for opening the inside of the body frame 4 to the outside thereof is formed between the body frame 4 and the body frame 4.
A seat 34 is removably attached to the upper surface of the vehicle body. The upper opening 45 is opened and closed by the attachment and detachment of the seat 34. When the fastening of the oil sump tank 50 to the vehicle body frame 4 is released, the oil sump is While the tank 50 is connected to the hydraulic cylinder 49 by the tube 51, the tank 50 can be selectively moved to the vicinity of either the side opening 46 or the upper opening 45.

In the above case, the fastener 53 may be operated through the upper opening 45 .

[0012]

[Operation] The operation of the above configuration is as follows.

In the process of manufacturing the motorcycle 1, when the oil sump tank 50 is to be filled with oil, first, before attaching the side cover 41 to the side of the body frame 4 (shown by a two-dot chain line in FIG. 1). ), The oil reservoir tank 50 is moved through the opened side opening 46 to the vicinity of the upper opening 46 while extending the slack 51a of the tube 51 (shown by a two-dot chain line in FIG. 1).

The oil sump tank 50 is filled with oil, and then the oil sump tank 50 is returned into the frame of the vehicle body frame 4 by an operation through the upper opening 46, and the vehicle body frame 4 is fastened by a fastener 53. To the side. Next, the side cover 41 is attached to the side of the vehicle body frame 4, and the side opening 46 is closed.

Therefore, the oil can be filled in the oil reservoir tank 50 by using the side opening 46.

By the way, it takes time and effort to remove the side cover 41 from the side of the vehicle body frame 4, while the removal of the seat 34 from the upper surface side of the vehicle body frame 4 is relatively easy. .

Therefore, when performing maintenance and inspection work on the oil reservoir tank 50 of the completed vehicle, first, the seat 34 is removed from the upper surface side of the vehicle body frame 4 to open the upper opening 45, and the upper opening 45 is opened. The above operation may be performed on the oil reservoir tank 50 through the opening 45.

Therefore, in the completed vehicle, the work on the oil reservoir tank 50 can be performed without removing the side cover 41 which is complicated to attach and detach.

In the above case, the fastener 53 may be operated through the upper opening 45.

In this manner, by removing the seat 34 from the upper surface side of the body frame 4, the upper opening 45
Is released, the fastener 5 through the upper opening 45 is opened.
By the operation of 3, the oil sump tank 5 to the body frame 4 side
0 can be released and the oil reservoir 50 can be moved to the vicinity of the upper opening 45 through the upper opening 45 (shown by a dashed line in FIG. 1), and maintenance and inspection of the oil reservoir 50 can be performed. Work can be done .
