[Problem that the invention seeks to solve]

However, in the above-mentioned model, the tanks are fixed between the intake system or drive system auxiliary equipment and the seat, so when performing maintenance on these auxiliary equipment, the side cover of the rear body must be removed. , maintenance work must be done from the side of the vehicle, especially for spark plugs and carburetors that are placed toward the front or top of the vehicle, which requires less work space and requires special tools. I couldn't figure it out.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a rear body structure that allows easy maintenance of various devices disposed within the rear body.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention includes a rear body at the rear of the vehicle body, a seat on the upper surface of the rear body,
In a motorcycle or tricycle equipped with a power unit that integrally forms an engine and a rear wheel drive device below, the seat is removably provided, and auxiliary equipment such as a carburetor or an air cleaner is installed in the rear body from the seat 1 to the lower part. It is characterized by its placement.

[For production]

Therefore, by removing the seat, maintenance of the auxiliary equipment arranged inside the rear body can be performed from the upper part of the rear body.

〔Example〕

Hereinafter, an embodiment in which the present invention is applied to a two-wheeled scooter will be described based on the drawings.

The scooter 1 has a main vibe 3 of a body frame 2 at the upper part of the vehicle body in the longitudinal direction, and sub-vibes 4, 4 each having a substantially U-shaped side surface are arranged on both sides of the lower part of the main vibe 3.
．． A head vibrator 8 that rotatably supports a par handle 7 that steers a front fork 6 on which a front wheel 5 is suspended is fixed to the front end of 4.4.

The head vibe 8 has a stay 9 that protrudes from the front of the vehicle.
1 board 10. A headlight 11 and a radiator 12 are fixedly installed, and the sub-vibrators 4, 4 are attached to a main vibrator 3 on a cross member 13 horizontally suspended on a rising portion of the rear side of the vehicle body.
While supporting the rear end, the middle part is connected to the stay 14 on the front side.
and are connected by a gusset 15 on the rear side, and floor vibes 16 and 16 are placed on both sides of the main vibe 3 and sub vibe 4 between the stay 14 and the gusset 15.
A large capacity fuel tank 17 is arranged in the inner space. Below the rising parts of the sub-vibes 4, 4 and the rear end inclined part continuous thereto, there are a link 20 pivotally supported on the pivot shaft 19 of the pivot gusset 18, and a rear suspension 21 pivotally supported on the rear end inclined part. As a result, the rear wheel 22 and a power unit 24 that integrally includes a drive device for the rear wheel 22 and a longitudinal cylinder 23 are suspended.

On the sloped rear end of Zabu Vibrator 4, 4, Gaito Day 25 is installed.
A loop-shaped seat rail 26 held by a guide stay 27 projects toward the front of the vehicle body, and a luggage rail 28 held by a guide stay 27 projects toward the rear of the vehicle body.

This body frame 2 includes a front flap 6 at the front of the body and instruments 5! f (10, a front cover 29 that integrally covers the headlight 11 and the radiator 12, a center cover 30a that extends from the cover 29 and covers the main vibe 3 in a protruding manner, and a low floor cover that covers the upper part of the floor pipe 16.16). The footrest cover 30 is integrally formed with the step floor 30b, and the power unit 24 at the rear of the vehicle is continuous with the footrest cover 30.
A rear body 31 that surrounds the upper part of the rear wheel 22 is provided.

This rear body 31 has a side cover 31a.

It consists of an inclined plate 3ib which is integrally formed with the side cover 318 and forms a rear lower inner wall of the seat 32, which will be described later, as well as a rear cover 31C and a lower cover 31 (1). The space inside the lower cover 31d communicates with the lower space formed by the side cover 31a and the rear cover 31C, and the lower cover 31d, which expands and slopes upward, has an upper opening 31f. has been done.

In the upper ffl opening 31f, a tandem seat 32 supported by the seat rail 26 is connected to a cross vibe 4 with a hook 32a on the rear side suspended between the inclined parts of the sub vibe 4.4.
a, attach the front end side to the rear body 31 with bolts 32b,
It is arranged to be removable.

Further, inside the rear body 31 below the seat 32, there is a battery 33, a carburetor 36 and a chamber 37 which are interposed in a connecting vibe 35 between the cylinder 23 and an air cleaner 34 which is integrally arranged in the power unit 24 in the vicinity thereof. Intake system auxiliary equipment such as
A luggage box 38 is fixedly installed on the luggage rail 28 at the rear of the vehicle.

Note that 12a is a radiator hose arranged between the radiator 12 and the water jacket of the cylinder 23.

As described above, in this embodiment, the fuel tank is placed at the bottom of the step floor, the seat is removably placed on the upper surface of the rear body, and the drive system and intake system auxiliary equipment such as cylinders and carburetors are installed inside the rear body. Because of this arrangement, maintenance of these auxiliary equipment can be done by removing the upper seat and working from the upper frontage of the rear body. In particular, it is easier to work on the spark plugs, carburetors, and other auxiliary equipment that are placed toward the front or top of the vehicle, and it takes up less space than when working from the side of the vehicle by removing the side cover. In combination with ensuring this, work efficiency can be further improved.
