DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reserve tank communicating with a radiator of a motorcycle.

[0002]

2. Description of the Related Art Japanese Unexamined Utility Model Publication No. Hei 2-135390 discloses a main frame having a vertically long cross section which extends rearward and rightward from a head pipe in a pair, a fuel tank supported on the main frame, and a head pipe. A radiator supported below the main frame in the vicinity and a reserve tank connected to and connected to the radiator are provided, and a cap portion provided at the top of the reserve tank is inserted into a recess formed at the bottom of the fuel tank. What is contained is shown. Also, the bottom of the reserve tank projects below the main frame, but is arranged on the back of the radiator and covered with a cowling.

[0003]

By the way, in order to check the remaining amount of the coolant in the reserve tank as described above, it is necessary to remove the cap and look into the tank. Also, the fuel tank volume must be sacrificed to some extent to allow for the placement of the cap. The present invention solves these problems.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a reserve tank for cooling water of a motorcycle according to the present invention is provided with a main body having a longitudinal cross section that extends rearward from a head pipe in a left-right pair. In a motorcycle including a frame, a fuel tank supported on the main frame, a radiator supported below the main frame near the head pipe, and a reserve tank connected to and connected to the radiator, In the space surrounded by the left and right main frames,
And the bottom of the fuel tank, accommodates a reserve tank which is disposed below, to expose the lower portion of the reserve tank from below the main frame upwardly of the radiator, and the exposed portion and the exterior portion of the transparent or translucent It is characterized by the following.

[0005]

[Function] The lower part of the reserve tank is below the main frame.
From the radiator above, the reserve
Since the lower portion of the tank is exposed between the main frame and the radiator, and the appearance is transparent or translucent, the remaining amount of the coolant can be visually observed without removing the cap. Moreover, it has good visibility and is outstanding
It has good appearance because it is provided at a suitable position. Plus main

it can.

Further, since a part to be accommodated in the space surrounded by the left and right frames is sufficient, the bottom of the fuel tank can be accommodated in this space to secure a sufficient volume.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS. FIG. 1 is a partially enlarged view of the main frame to show the arrangement of the reserve tank, FIG. 2 is an enlarged view from the front of the vehicle body (in the direction of arrow A in FIG. 1), and FIG. It is a side view of a two-wheeled vehicle.

As shown in FIG. 3, a main frame 1 having a vertically long cross section is provided in the front-rear direction of the vehicle body. The main frame 1 extends rearward and rightward from the head pipe 2 in pairs (see FIG. 2).

A fuel tank 3 is supported on the main frame 1, and its bottom 4 enters a space (FIG. 1 described later) surrounded by the left and right main frames 1. In this space, a reserve tank 5 is arranged near the head pipe 2 and below the front end of the bottom 4.

The cap 6 of the reserve tank 5 is close to the bottom 4 and the lower part 7 projects below the main frame 1 and projects to the upper part of the radiator 8.

The radiator 8 is supported by a down frame 9 extending downward from the main frame 1 in a forwardly inclined state. The radiator 8 is connected to the engine 10 by water pipes 11 and 12.

The engine 10 is supported by a pivot frame 13 connected to the down frame 9 and the rear end of the fuel tank 3.

A rear wheel 15 is supported on the pivot frame 13 via a swing arm 14. Fuel tank 3
Are supported at a front end 16 to a portion near the head pipe 2 and at a rear end side to a stay 17 of the main frame 1.

The seat 18 and the rear fender 19 extending continuously to the rear of the fuel tank 3 are supported by a seat rail 20 and a rear stay 21 extending obliquely upward and rearward from the fuel tank 3 and the bottom 4.

The head pipe 2 has a front fork 22
Are supported, and a front wheel 23 is provided at a lower end of the front fork 22.
Is supported.

As apparent in FIGS. 1 and 2, the head pipe 2 is formed parts that gives extending rearwardly integrally thereon forms a substantially U-shaped upper surface portion 24, the side surface portion 25 A rib 26 is formed in the front-rear direction, and the lower portion is also a substantially V-shaped lower surface portion 27. The front end of the main frame 1 is welded to the side surface 25 in an open state (FIG. 2).

The space 28 surrounded by the left and right main frames 1 shown in FIG. 1 is closed at the upper part by the bottom part 4 of the fuel tank 3 and opened at the lower part to form an opening 29.

The reserve tank 5 is made of a translucent or transparent resin so that the remaining amount of the coolant can be checked from the outside.

The lower part 7 extends from the opening 29 to the main frame 1.
And extends forward and communicates with the upper tank 31 of the radiator 8 via a hose 30.

Next, the operation of this embodiment will be described. 1 and 2, the lower portion 7 protrudes outside the main frame 1 and is exposed above the upper tank 31 of the radiator 8.

Therefore, since the lower part 7 is an external part and this part is made of a transparent or translucent resin, the remaining amount of the cooling liquid can be quickly and visually checked without removing the cap 6.

Even if the front of the vehicle body is covered with a cowling, the front of the radiator 8 is usually formed as an opening for taking in the traveling wind, and the lower portion 7 is located on the radiator 8. Even in such a case, it can be surely visually observed, and the visibility is improved.

Further, since it is unnecessary to remove the cap 6 and check the remaining amount, the cap 6 can be disposed at a relatively deep position in the space 28, and the reserve tank 5 is a part of the lower part. 7 can be exposed.

Therefore, the portion accommodated in the space 28 can be made small enough not to affect the volume of the fuel tank 3, so that the fuel tank 3 has a sufficient capacity without sacrificing its volume. Secured.

[0025] In addition, since the unnecessary portion of the reserve tank 5 is not exposed, it is possible to clean the exterior, its
In addition, since it is provided at an inconspicuous position, the appearance is improved. Moreover, below the main frame 1 and above the radiator 8
Using the gap formed between
It can be easily exposed.

[0026]

According to the present invention, the bottom of the fuel tank is accommodated in a relatively deep space surrounded by the left and right main frames having a vertically long cross section, the reserve tank is accommodated below the fuel tank, and the lower part of the reserve tank is accommodated. Below the mainframe
From the radiator above, the reserve
The lower part of the tank was an exterior part exposed between the main frame and the radiator, and this part was made transparent or translucent.

Therefore, the remaining amount of the coolant can be visually confirmed without removing the cap, and the remaining amount of the coolant can be easily and quickly checked. Moreover, visibility is improved.

Further, since the reserve tank can be provided without sacrificing the capacity of the fuel tank, the capacity of the fuel tank can be sufficiently secured. In addition, it is provided in an inconspicuous position
Good appearance. Also, beneath the mainframe and
Reserve by utilizing the gap formed between the upper part of the feeder
The tank can be easily exposed.

In addition, the appearance can be improved.
