That is, the reservoir tank 32 is attached to the upper stay 30 with the bolt 33 and is fixed to an attachment piece 26c provided on the left upper body of the radiator 26 (right side in front view). Since the wind passing through the radiator 26 enters from the front and is guided to the side, the brackets 26a, 26b and the mounting pieces 26c are arranged above and below the radiator 26, so that the brackets 26a, 26b does not interfere. As shown in FIG. 12, the radiator 26 has a core between the left and right tanks 121 and 122, and the cooling water passes from the left tank 121 to the core by a two-point oblique line 124 vertically. It is divided. The arrows in FIG. 12 indicate the flow of the cooling water.

As shown in FIG. 11, an intermediate cover 34 is disposed behind the radiator 26 and in front of the head pipe 2, and between the intermediate cover 34 and the leg shield 28, Many lead wires and hoses 35 connected to the switch case 10, the master cylinder 11, and the like are inserted therethrough. The intermediate cover 34 can protect the lead wires and the hoses 35 from hot air after cooling the radiator 26, and
The wind from 6 can be guided to the side. The flow of the wind is shown by arrows in FIG.

The front cover 27 includes a front cover 37 and a rear cover 3 as shown in FIGS.
8, the rear cover 38 and the front cover 37 are formed to have substantially the same width.

As shown in FIG. 7 and the like, the front cover 37 is formed with a wind introduction opening 37a for introducing traveling wind to the radiator 26, and the rear cover 38 is opposed to the wind introduction opening 37a. Louvers 38a are formed. As shown in FIGS. 13 and 2, the front cover 37 has a plurality of bosses 37b projecting rearward, and the rear cover 38 is fixed to these bosses 37b by screws 39. . In this case, since the mounting point (the screw 39) cannot be seen from the front, the appearance quality is ensured. Incidentally, reference numeral 100 in the figure denotes a headlight, which is attached to the front cover 27.

The front cover 27 assembled in this manner is attached to the leg shield 28 at several places at the peripheral edge. In this mounting state,
Exhaust ports 40 are formed at two places on the left and right sides by the covers 27 and 28, and hot air that has passed through the radiator 26 and has been heat-converted passes through the exhaust ports 40 to the outside of the vehicle.

Further, the front cover 3 is attached to the rear cover 38.
A louver is formed in the vicinity of the upper edge of the radiator 7, and discharges the heat of the radiator 26 via the discharge port 101 when the vehicle stops or the like.

A mounting piece 38b is formed at an inner position of the bracket, and the mounting piece 38b is screwed to the front lower cover 42 so that the mounting piece 38b can be mounted / removed via the air outlet 40.

As described above, the front cover 27 has a double structure consisting of the front cover 37 and the rear cover 38 which are connected to each other and have substantially the same width, so that the air introduction opening 37a is enlarged to make the radiator 26, the rigidity can be secured, the degree of freedom in design can be improved, and the appearance quality can be secured. In other words, the two covers 37,
By the mutual reinforcement of 38, rigidity can be ensured, and since there is no need to form a reinforcing rib, the appearance quality can be improved without causing sink marks on the surface of the front cover 37. The front cover 37 has a wind introduction opening 37a.
By forming the louver 38a on the rear cover 38, the degree of freedom of the shapes of the two covers 37, 38 is improved, and the influence of sink marks due to the louver 38a is not exposed on the vehicle surface, so that the appearance quality is improved. Can be secured. By the way, if the wind introduction opening 37a is enlarged with one piece,
If the rigidity is weakened and the wall thickness is increased to secure the rigidity, the weight increases, and if the reinforcing ribs are formed on the back surface, sink marks occur on the surface and the appearance quality deteriorates.

Further, the portion X in FIG. 1 corresponds to FIGS.
It is shown as follows. That is, this portion X is configured by combining the resin front lower cover 42, the leg shield 28, and the under cover 44.

That is, as shown in FIG. 16, the front lower cover 42 is formed with a folded portion 42a on the lower side, and the under cover 44 is engaged with the folded portion 42a. In the case where the folded portion 42a is not formed, the position where the front lower cover 42 and the under cover 44 are fitted is P in FIG. 16, and the fitted portion is visible from the front, and the appearance quality is degraded.
Therefore, if the folded portion 42a is formed, the mating portion is on the back side, so that the appearance quality is secured.

However, when the folded portion 42a is formed, the direction in which the front lower cover 42 is removed is in the direction of the arrow in FIG. 16, so that the upper end edge 42b of the front lower cover 42 is bent toward the center of the vehicle. Cannot be formed.

Therefore, the side edge portion 28 of the leg shield 28
a, a plurality of louvers 28b are formed on the side edges 28a.
And the upper edge 42b of the front lower cover 42.

In this manner, the appearance quality as viewed from the front can be ensured, and the louver 2 of the leg shield 28 can be secured.
8b, a part of the hot air that has passed through the radiator 26 can be exhausted, and at the same time, the hot air enters through the hole 119 formed in the front lower cover 42 and is guided by the guide piece 34a formed integrally with the lower part of the intermediate cover 34. Air can also be exhausted from between the louvers 28b (see FIG. 16).

As shown in FIGS. 1, 7, and 17, a footrest board 47 on which a foot is placed is provided behind the leg shield 28. In the footrest board 47, a tunnel portion 47a protruding upward at the center in the vehicle width direction is formed along the vehicle front-rear direction.
As shown in FIGS. 7 and 17, a storage recess 47b for storing the battery 48 is formed in the tunnel portion 47a, and an inner lid 49 is disposed above the battery 48 stored therein. It has become. A lid 50 for opening and closing the storage recess 47b is provided so as to be rotatable up and down around a front end 50a. A maintenance lid 51 is detachably provided on the rear side of the lid 50. As shown in FIG. 7, the maintenance lid 51 has an opening formed in a rear wall 47c of the housing recess 47b. A fitting portion 50b that fits with the opening 47d and closes the opening 47d is formed. The lid 50 also covers the front part of the maintenance lid 51.

In such a structure, the battery 50 is opened by opening the lid 50 around the front end 50a.
Can be replaced, and an injection port of an oil tank (not shown) is exposed from a notch formed in a front portion of the maintenance lid 51 so that oil can be injected.

Further, since the alignment line between the maintenance lid 51 and the footrest board 47 is inclined obliquely forward, only the maintenance lid 51 can be easily removed without removing the seat 59, the footrest board 47 and the like. By removing the lid 51, the engine 5
3 can be easily repaired. In particular, since the opening 47d of the footrest board 47 is opened, setting of the carburetor and the like becomes extremely easy through the opening 47d.

Further, an anti-theft bar 54 is provided around the footrest board 47 for the purpose of preventing the vehicle from being stolen. That is, the anti-theft bar 54
As shown in FIGS. 5 and 6, one end 54a is fixed to the right pipe 4 of the frame 1 by welding, and the other end 54b
Is fixed to the outer surface of an engine mount bracket 4 a for suspension of the engine 53 fixed to the right pipe 4. Thus, as shown in FIGS. 3 and 4, the anti-theft bar 54 is disposed in a space behind the side rear end 47e of the footrest board 47 and inside the side edge 47f. The space extends to the rear end 47e so as to extend the space backward. The anti-theft bar 54 is located above the muffler 56.

In this way, the anti-theft bar 54
Since it does not protrude to the side of the vehicle body, it does not become an obstacle, improves the handling performance of the vehicle body, and allows the vehicle body to be downsized.

Further, since there is no need to form a notch for the anti-theft bar 54 in the middle of the side of the footrest board 47, the structure is simple and the appearance quality is improved.

Further, since the anti-theft bar 54 can be used as a part of the foot mounting space, the foot mounting space can be increased. On the contrary, if the foot mounting space having the same size as the conventional one can be used, Mold cost and weight can be reduced by reducing the size of the footrest board 47.

Further, as shown in FIG. 6, the right side pipe 4 of the frame 1 to which the anti-theft bar 54 is fixed extends right and left behind the vehicle, and the anti-theft bar 54 is fixed to the expanded portion. Therefore, the anti-theft bar 54 does not need to prolong the amount of protrusion to the side, so that the rigidity of the anti-theft bar 54 can be ensured and the weight can be reduced.

Further, the other end 54b of the anti-theft bar 54
Is fixed to the engine mount bracket 4a having high rigidity, and the length of the anti-theft bar 54 is further shortened, so that rigidity can be secured and the weight can be reduced.

Further, since the footrest board 47 is inclined upward and rearward, the antitheft bar 54 provided at the rear end side is set at a relatively high position, so that the locking work is improved. . The rear side of the side rear end 47a of the footrest board 47 is a part that has not been used in the past, but that part is effectively used by the anti-theft bar 54. Further, since the anti-theft bar 54 is disposed on the muffler 56, the contact of the foot with the muffler 56 can be prevented.

Although the anti-theft bar 54 is provided on one side of the vehicle body here, it may be provided on both left and right sides.

On the other hand, in FIG. 18, FIG. 19 and FIG.
Reference numeral 8 denotes a storage box, and the storage box 58 is inserted between the right pipe 4 and the left pipe 5 of the frame 1,

There is formed a weir portion 58f protruding upward from a. Then, a sealing member 68 attached to the sheet 59 comes into contact with the upper edge 67a to be sealed.

As described above, the bottom wall 58 of the storage box 58
b is inclined so that the rear thereof is lowered, and the rear portion 58c side of the bottom wall 58b is formed so as to enter a space formed by the upper surface of the engine 56 and the rear wheel 64, so that it has not been conventionally used. The space can be effectively used, and the center of gravity can be reduced. In addition, due to the inclination of the bottom wall 58b, luggage other than the helmet 65 is always stored rearward, so that the luggage does not rattle or move.

Further, since the rear part 58c of the bottom wall 58b of the storage box 58 is formed deep, the luggage is stored in the rear part 58c and the hinge of the sheet 59 for opening and closing the storage box 58 is connected to the front end 59a. , The luggage can be taken in and out without opening the seat 59 so much.

Further, the rear wall 58d of the storage box 58
Is inclined forward in conformity with the shape of the helmet 65, so that there is no useless space in the storage space of the storage box 58 as compared with the case where the rear wall is formed along the vertical direction. The space for disposing other components such as the fuel tank 70 can be increased, and the size of the seat 59 and the vehicle body can be reduced. Moreover, in the resin storage box 58, the screw holes for attachment to the vehicle body frame 1 are directed obliquely upward and forward along the inclination direction of the rear wall 58d, in response to the rear wall 58d being inclined forward. doing. As a result, the die can be removed without the need for a slide die or the like.

The cover 72 is integrated with the opening 71a of the tank body 71 by being fitted and thermally fused. As shown in FIG. 18, a filler cap 73 is removably attached to an oil inlet 72c of the filler cover 72.

As shown in FIG. 18, the fuel tank 70 has a projecting piece 7 formed on the upper part of the front surface of the tank body 71.
1b is fixed to the storage box 58 with the screw 74,
The lower front portion is supported by a cross pipe 6 that crosses the right and left pipes 4 and 5, and the lower rear portion is supported by a support member 76 of the frame 1 via a damper 75. A tandem seat 78 is provided above the fuel tank 70, and the tandem seat 78 is also attached to the storage box 58. The opening 78a of the tandem sheet 78
Therefore, the filler cap 73 and the like of the fuel tank 70 face upward.

When the fuel tank 70 and the tandem seat 78 are attached to the storage box 58 in this manner, the side cover 67 and the rear side cover 110 are also attached to the storage box 58. Because of the positional relationship, the alignment accuracy of the side cover 67, the rear side cover 110, the fuel tank 70, the tandem seat 78, and the like is improved.

Further, since the receiving portion 72b is provided integrally with the fuel tank 70, there is no need to separately prepare a device for receiving the overflowing fuel.

Further, the engine mount brackets 4a and 5a of the frame 1 are connected to the engine 5 via a link mechanism.
3 are provided. The engine 53 has a cylinder that extends substantially horizontally forward from the crankcase, and a transmission 79 that extends rearward on one side of the crankcase and supports a rear wheel 64 at a rear end is integrated with the crankcase. Is suspended on the vehicle body frame 1 so as to be able to swing up and down. Note that reference numeral 80 in the figure denotes a shock absorber.

More specifically, as shown in FIG. 24, a drive shaft 82 projects from the transmission 79 side along the vehicle width direction.
a and spline-coupled to each other, and a nut 84 is screwed into the drive shaft 82 so that the base member 8
3 is fixed to the drive shaft 82.

A disc plate 86 of a disc brake device 85 is attached to the base member 83 on the side surface of the transmission 79 by bolts 87, and a caliper 88 of the disc brake device 85 is fixed to the transmission 79. . A pair of pads 89 is detachably inserted into the caliper 88, and the pads 89 are detached by pulling out pins (not shown).

Further, a total of three stud bolts 90 are provided on the side of the base member 83 opposite to the disk plate 86.
These bolts 90 are inserted into the respective insertion holes 64b of the wheel portion 64a of the rear wheel 64, and the nuts 91 are screwed together, whereby the rear wheel 64 is fixed to the base member 83.

Further, a muffler 56 is disposed on the right side of the rear wheel 64 (on the side opposite to the transmission 79). The muffler 56 is arranged such that a nut 91 for mounting the rear wheel 64 is exposed. As shown in FIGS. 1, 3, and 18, they are disposed upward and pass over the nuts 91.

The rear fender 93 is divided into a front part 94 located above the rear wheel 64 and a rear part 95 inclined obliquely downward from the rear end of the front part 94. 95 can be removed from the front side 94.

According to this configuration, the rear wheel 64 can be attached and detached without removing the caliper 88, the disk plate 86, and the muffler 56. That is, when removing the rear wheel 64, since the muffler 56 is disposed above, the nut 91 can be removed without the muffler 56 becoming an obstacle. Then, the rear wheel 64 is moved in the direction of the arrow in FIG. 24 to remove it from the stud bolt 90, and the tire portion 64 c of the rear wheel 64 is passed between the muffler 56 and the stud bolt 90 of the base member 83, and the rear wheel 64 is moved. Remove from the body. In this case, since the rear wheel 64 is pulled rearward, the rear side portion 95 of the rear fender 93 is in the way,
The rear fender 93 is divided into two parts, and the rear side part 95
Since the rear wheel 64 can be detached only, when the rear wheel 64 is attached and detached, only the rear side portion 95 is detached, so that there is no hindrance when attaching and detaching the rear wheel 64.

In this case, the rear wheel 64 is attached to the base member 83 and the base member 83 is attached to the drive shaft 82. In order to move the stud bolt 90 in the direction, it is sufficient to move the stud bolt 90 by at least the protrusion amount L2. On the other hand, when the base member 83 and the rear wheel 64 are integrally formed, the coupling stroke L1 between the drive shaft 82 and the base member 83 requires transmission of a certain amount of torque. Therefore, it is necessary to set it slightly longer. However, by dividing the base member 83 and the rear wheel 64 as in the present invention, even if the coupling stroke L1 between the base member 83 and the drive shaft 82 needs to be long, the coupling between the base member 83 and the rear wheel 64 is required. Since the stroke L3 is formed by the plurality of stud bolts 90 located around the drive shaft 82, the transmission torque is dispersed, so that the stroke L3 can be shorter than the coupling stroke L1. When removing the rear wheel 64, there is no need to remove the base member 83 from the drive shaft 82, and the rear wheel 64 may be removed from the base member 83.

As a result, since the moving amount L2 of the rear wheel 64 can be shortened, even if the muffler 56 is arranged on the side, the wheel portion 64 of the rear wheel 64 can be moved from the stud bolt 90.
a can be removed and the muffler 56 is disposed on the upper side, whereby the thick tire portion 64c can be pulled out from between the muffler 56 and the stud bolt 90 of the base member 83.

When the pad 89 is replaced from the caliper 88, a pin (not shown) is pulled out, and
It can be pulled out as shown by the two-dot chain line.

In the above embodiment, the present invention is applied to a scooter of a motorcycle, but is not limited to this, and it is needless to say that the invention can be applied to a tricycle and the like.
