5b is fixed to the seat rail 24 by welding.

Further, a reinforcing tube 26 is provided between the rear end 25b of the back stay 25 and the rear end 24b of the seat rail 24.

In addition, a cross tube 27 for connecting the left and right seat pillars 21 is installed at an intermediate portion of the seat pillar 21 in the up-down direction, while a rear end 24b of both seat rails 24 is provided as shown in FIG. As shown, the seat bracket 30, the first bracket 31, and the second bracket 32
Has been erected.

Further, as shown in FIG. 4, a bracket 35 for a battery box is fixed to the back stay 25, and a hole 35a formed in the bracket 35 is inserted through a grommet 37 into the bottom surface of the battery box 36. The battery box 36 is placed so that the protrusion 36f provided on the air cleaner 3 is inserted.
8 and is supported.

More specifically, the air cleaner 38 is shown in FIG.
As shown in FIGS. 0 to 13, side opening portions 3 are formed in side surfaces of the box-shaped air cleaner main body 39 along the vehicle front-rear direction.
9a is formed, and an element replacement cover 40 for opening and closing the side opening 39a is detachably provided. By opening the cover 40, the element 41 disposed inside the air cleaner main body 39 can be replaced.

In FIG. 8, reference numeral 44 denotes a fuse holder, reference numeral 45 denotes a CDI unit, and reference numeral 46 denotes a starter relay.

The air cleaner 38 is connected to the body frame 11 via an air cleaner bracket 47 shown in FIG.
, Is arranged below the seat 17.

A separate battery box 36 is attached to the air cleaner 38 on the side surface 39b of the air cleaner main body 39 along the vehicle front-rear direction opposite to the side on which the cover 40 is attached. The battery box 36 is attached to a side surface 39 b of the air cleaner 38 opposite to the side on which the drive chain 16 is provided.

On the side surface 39b of the air cleaner main body 39 on the side where the battery box 36 is mounted, a concave portion 39c is formed on the lower side toward the center of the vehicle.
12c is provided with an insert nut 39d (FIG. 12).
And FIG. 13).

On the other hand, this battery box 36
As shown in FIGS. 4 to 17, a substantially rectangular battery 48 is provided.
Is formed at the upper end of the side surface portion 36b of the battery storage recess 36a.
Two bolt insertion holes 36c are formed, and bolts 49 are inserted into these bolt insertion holes 36c and screwed to insert nuts 39c provided in the air cleaner main body 39 (see FIG. 9 and the like).

A hook 36e is provided on the upper side of the opposing side surfaces 36b and 36d of the battery box 36.
Are formed, and the battery band 50 is hooked on both hook portions 36e, so that the battery 48 is held in a state housed in the battery box 36.

When the battery box 36 is disposed, a part of the upper portion of the battery box 36 is
The air cleaner 38 is attached so as to be inserted into the concave portion 39c of the side surface portion 39b.

In FIG. 8, reference numeral 51 denotes a battery hose.

By thus separately providing the battery box 36 and the air cleaner 38, the degree of freedom in design is improved, and the position of the battery box 36 attached to the side of the air cleaner 38 in the vehicle width direction is lowered. The side of the air cleaner 38 can be bulged above the battery box 36. Therefore, unlike the conventional integrated type, the air cleaner 38 can be mounted on a vehicle while securing a large capacity.

Further, since the battery box 36 is mounted on the side surface 39b of the air cleaner main body 39 on the side opposite to the mounting side of the cover 40, the battery box 36 can be mounted without hindering the replacement of the element 41. Moreover, the battery box 36 is provided with the air cleaner 3.
8, the battery box 36 can be arranged at a lower position because it is attached to the side surface 39b opposite to the side where the drive chain 16 is provided.

Further, the air cleaner 38 has side portions 39.
A concave portion 39c is formed at the lower side of the vehicle body b toward the center of the vehicle, and a part of the battery box 36 is inserted and attached to the concave portion 39c, so that the vehicle width including both the air cleaner 38 and the battery box 36 is combined. By arranging the battery box 36 attached to the outside of the vehicle from the center position at a position lower than the air cleaner 38, the width of the vehicle in the upper direction can be reduced, and the width in the downward direction can be increased. Of the rear arm pivot 4 of the body frame 11 while ensuring the
2, the supporting rigidity of the rear arm 14 can be increased.

Further, by providing the insert nut 39d on the air cleaner 38 side, it is not necessary to make a hole in the air cleaner main body 39, and it is not necessary to make an improvement for ensuring the airtightness.

[0031]

As described above, according to the first aspect of the present invention, since the battery box and the air cleaner are separated from each other, the degree of freedom of design is improved, and the width of the vehicle relative to the air cleaner is increased. The position of the battery box attached to the side of the air cleaner can be lowered, and the side of the air cleaner can be bulged above the battery box. Therefore, unlike the conventional integrated type, the vehicle can be mounted on a vehicle while securing a large capacity of the air cleaner.

According to the second aspect of the present invention, in addition to the above effects, the battery box is attached to the side surface of the air cleaner body opposite to the side to which the cover is attached, so that the replacement of the element is not hindered. The battery box can be attached.

According to the third aspect of the present invention, in addition to the above effects, the air cleaner is formed with a concave portion that is recessed toward the center of the vehicle at a lower portion of the side surface portion, and a part of the battery box is formed in the concave portion. Since it is inserted and attached, the width of both the air cleaner and the battery box in the vehicle width direction can be reduced, and the battery box attached to the outside of the vehicle from the center position is located at a position lower than the air cleaner, so that the upper vehicle width can be reduced. Can be made narrower and wider as it goes downward, so that the feet of the occupant can be secured. Moreover, since the upper portion of the air cleaner can be expanded laterally above the battery box, the capacity of the air cleaner can be further increased.

According to the fourth aspect of the present invention, in addition to the above effects, the battery box is provided to the air cleaner with respect to the air cleaner.
Since the battery box is attached to the side surface opposite to the side on which the drive chain is provided, the battery box can be arranged at a low position.
