Abstract

PURPOSE:To improve the easiness for a rider to foot the ground and to ride in a vehicle by providing an oil filler port in a tank to correspond to the bottom of a seat protruding part and storing this oil filler port in a rising wall part formed in a seat bottom plate. CONSTITUTION:A tank 9 provides in its upper surface side an oil filler port 9b to be protruded for facilitating supply of oil. The oil filler port 9b of the tank 9 corresponds almost to the bottom of a protruding part 8a of a seat 8, and a bottom part 7 forms a diagonally rising wall part 7a storing in its inside the oil filler port 9b in a manner wherein it is prevented from coming into contact with the bottom plate 7. Thus, enabling the seat to decrease its height, a motorcycle can be obtained excellent in the easiness for a rider to foot the ground and to ride in a vehicle when it is stopped. Further, the diago nally rising wall part is provided in a position almost corresponding to the oil filler port in the bottom of the protruding part holding a hip part of the rider, so that cushioning performance is given no influence even when the seat is decreased in its thickness by this diagonally rising wall part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motorcycle having a tank for oil or the like installed under the seat.

In motorcycles that are not driven at relatively high speeds and are ridden with normal clothing, a large space is provided in front of the seat for the rider's legs to cross, making riding easier.

In such motorcycles, the engine and other main parts of the body are usually installed below the seat, but the oil tank is designed so that oil and gasoline are supplied to the engine by gravity, and it is easy to refuel the tank. With this in mind, it is placed directly below the seat.

Furthermore, since the lower part of the tank is occupied by the suspension and the vehicle body frame that supports it, the minimum height of the tank is limited by these.

On the other hand, it is desirable to make the seat height as low as possible considering the ease of leg attachment and ease of riding when the vehicle is stopped, but in addition to securing the capacity of the tank mentioned above, the fuel filler port should protrude to make it easier to refuel. If this happens, there is a problem in that it comes into contact with the bottom plate of the seat, making it impossible to lower the height of the seat.

The present invention has been made to solve such problems, and provides a motorcycle in which a tank for oil, etc. is installed at the bottom of a seat having a protrusion for holding the rider's buttocks. The seat is characterized in that a refueling port of a tank for oil or the like substantially corresponds to the lower part of the protruding portion of the seat, and an inclined rising wall portion is formed on the bottom plate of the seat to accommodate the refilling port.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically explained below using embodiments shown in the drawings.

Fig. 1 shows a motorcycle according to the present invention: In Fig. 1, 1 is a main vibrator constituting the vehicle body frame, and a front wheel 2 and a rear wheel 3 are located in front and behind the main vibrator 1. are provided, and this front wheel 2, rear wheel 3
A front fender 4 and a rear fender 5 are provided above, respectively. Further, an engine 6 is provided at the lower center of the main vibe 1, and a seat 8 is provided above the rear end.

As shown in the detailed drawings of FIGS. 2 and 3, a tank 9 for storing oil and a battery 10 are installed in front and behind each other at the bottom of a seat 8 installed at the upper part of the rear end of the main vibrator L. The rear fender 5 is located below these.

The tank 9 is provided with a protruding oil filler port 9b on its upper surface side to facilitate refueling, and oil can be replenished by opening the cap 9a of the oil filler port 91]. Oil in the tank 9 is supplied to the engine 6 via a vibrator 11 connected to the bottom.

The seat 8 has a protrusion 8a for holding the rider's buttocks at the rear and preventing the rider from moving during acceleration, and a bottom plate 7 on the lower surface for supporting the rider's load.

Then, the fuel filler port 9b of the tank 9 is made to substantially correspond to the lower part of the protruding portion 8a, and an inclined rising wall portion 7a is formed on the bottom plate 7, and the fuel filler port 9b is housed inside thereof so as not to come into contact with the bottom plate 7. There is.

The battery 10 is housed and fixed in a box 12 fixed to the vehicle body frame. Furthermore, a mudguard 13 is fixed to the front end of the rear fender 5. The rear fender 5 is integrally molded from resin. As shown in the perspective view of FIG. 4, this rear fender 5 has hook-shaped locking portions 14 and 15 at the center and front portions of the upper surface, respectively.

The rear fender 5 engages the locking portion 14 in the center with the bracket 16 on the vehicle frame side, and
The front locking portion 15 is engaged with the rear cushion pad 18 on the vehicle body frame side, and in this state, the center locking portion 14 is connected together with the bottom plate of the box 12 that houses the battery 10. 17, and are collinearly fixed together.

As described above, in the present invention, the tank 9 for storing oil is installed at the upper part of the vehicle body directly below the seat 8 in order to supply oil to the engine 6. Further, the lower part of the tank 9 is occupied by the rear fender 5 and the vehicle body frame supporting it, and the rear fender 5 is installed with sufficient margin for the diameter of the rear wheel 3 and its vertical swing stroke. Therefore, if the volume of the tank 9 is secured and the fuel filler port 9b is made to protrude from the top side of the tank 9 to facilitate refueling, the height of the tip of the fuel filler port 9b will be added to the total height, but this will increase the height of the rider. The fuel filler port 9b is made to approximately correspond to the lower part of the protrusion 8a of the seat that holds the buttocks, and the inclined rising wall portion 7a is formed on the bottom plate 7 of the seat, and the fuel filler port 9b is housed inside this wall, so that the seat 8 Its height can be reduced without any contact.

Furthermore, since the inclined rising wall portion 7a is not formed at a fixed position of the rider during driving, even if the seat thickness is reduced due to the inclined rising wall portion 7a, the cushioning performance is not affected.

In addition, although the above-mentioned embodiment has been described with respect to a tank for storing oil, a tank for storing gasoline may be used instead.

As described above, the present invention provides a motorcycle in which a tank for oil, etc. is installed below the protrusion of the seat, which has a protrusion for holding the buttocks of the rider. The vehicle is characterized in that an inclined rising wall portion is formed on the bottom plate of the seat so as to substantially correspond to the fuel filler port and accommodate the fuel filler port.

Therefore, when an oil tank is installed directly under the seat of a motorcycle that is ridden with normal clothes on, the lower part is occupied by the fender and the body frame that supports it, and the minimum height of the tank is is limited, and if the fuel filler port is made to protrude from the top side after securing its capacity, the height of the tip of the fuel filler port will be added to the overall height, and the height of the seat will also become higher, but it will be inclined to the bottom plate of the seat. A rising wall is formed, and the fuel filler port is housed inside the wall so that it does not come in contact with the bottom plate, allowing the seat height to be lowered, making it easier for the rider to attach his/her legs when the vehicle is stopped, and for easy riding. You can get a two-wheeler. Moreover, the above-mentioned sloping rising wall portion is provided at a position approximately corresponding to the fuel filler port below the protrusion that holds the rider's buttocks, and is not formed at the rider's regular position during driving. It has the characteristic that even if the sheet thickness becomes thinner, the cushioning performance is not affected.
