DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an arrangement structure for a wiper wiper provided in a motorcycle.

When installing a washer device on a motorcycle along with a wiper device that wipes off the windshield located in front of the handlebar, the tank and nozzle of the washer device should be placed as close together as possible, taking into consideration maintenance of the tube that connects them. It is desirable to realize the above so that the tank containing liquid and having a certain weight does not have much influence on the operating load of the handle.

The present invention was made in response to such demands, and its purpose is to shorten the tube connecting the tank and nozzle, thereby improving maintainability, and reducing the handle operating load. To provide a structure for arranging a wiper seat for a motorcycle so as not to have much influence on the vehicle.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1 is a schematic side view of a motorcycle, Figure 2
The figure is a perspective view of the same, FIG. 3 is a partially cutaway side view of a portion of the washer device in which a tank is arranged, and FIG. 4 is a plan view of the same.

The front part of the body 2 of the motorcycle 1 constitutes a leg shield 3, the rear part constitutes a seat post 5, and the middle part constitutes a floor 4. The lower part of the leg shield 3 is a front wheel 6, and the rear lower part of the seat post 5 is a power shield. Rear wheels 8 are supported through units 7, respectively. The handle pipe 9 faces the top of the leg shield 3,
A fairing 10 is provided in front of the handle 9, and this 10 is attached to the left and right grips 9 of the handle 9.
Grip cover part 10 that covers a and 9b from the front
a, 10a. Furthermore, a windshield 11 is provided upright on the upper part of the fairing 10, and an inner windshield 11 is provided so as to cover the front upper part of the handle panel 13, which is installed at the upper middle part of the handle pipe 9 and incorporates a meter unit, etc., to the lower part of the windshield 11. A panel (decorative panel) 12 is provided.

And 10 fairings, 1 windshield
1 and the inner panel 12 are fixed to the support frame 14 with screws 15 to form an assembly, and by connecting the stays 16 fixed to the support frame 14 to the handle pipe 9, these 10, 11 are assembled.
and 12 are collectively installed on the vehicle body, and the windshield 11 rotates with the steering movement of the handle 9 and stands upright in the direction of travel of the vehicle.
A wiper device 20 is provided.

The wiper motor 21 of the wiper device 20 is fixed to the central rear surface of the support frame 14, and the upper part is covered by the inner panel 12, and the swing of the arm 23 at the tip of the shaft 22 causes the wiper blade 24 at the tip of the shaft 23 to act as a windshield. 11 Wipe the front.
A wiper switch 25 is disposed on the inner panel 12 near the handle grip 9a. This wiper device 20 is also assembled together with the fairing systems 10, 11 and 12.

As shown in the figure, the handle pipe 9 and wiper motor 2
A space S is provided between the tank 31 of the washer device 30 and the tank 31 of the washer device 30 in the space S.
was placed.

The tank 31 is attached to the handle pipe 9 directly or via a bracket (not shown) so as to be adjacent to the rear surface of the wiper motor 21.
The washer fluid in the tube 33 is driven by a washer motor 32 connected to the front part of this 31.
Air is emitted from a nozzle (not shown) disposed near the tip of the arm 23 through the windshield 11.
Water is sprayed in front.

Since the tank 31 is placed in the front central part of the handle pipe 9, the length of the tube 33 that connects the tank 31 and the nozzle is extremely short compared to, for example, placing the tank in the trunk provided in the leg shield. Therefore, the cost and weight can be reduced, the maintainability of the tube 33 is improved, and the tank 31 is brought closer to the steering center of the handle pipe 9, so that the operating load of the handle 9 is not affected much. do not have.

Since the center of the left and right width of the tank 31 coincides with the center of the vehicle width, the tank 31 is disposed between the forwardly convex fairing 10 and the handlebar 9.
It is also advantageous in terms of measures to prevent the vehicle body from tilting due to the weight of the washer fluid when the vehicle is parked on a slope, for example.

Further, in the case of the electric washer device 30 as in the embodiment, the tube 33 can be kept at the shortest length, so the load on the washer motor 32 is reduced, and the washer device 30 can be used effectively under limited electric capacity. Although the device itself can be made smaller and lighter in weight, the present invention is not limited to electric type washer devices, and the above-mentioned effects can also be achieved in manual type washer devices.

Further, when the tank 31 is disposed within the fairing 10, the washer device 30 can also be assembled into the fairings 10, 11, and 12 together with the wiper device 20. In this case tank 31
shall be attached to the support frame 14, and power sources shall be set as necessary. This embodiment greatly improves the ease of assembly for mounting on the vehicle body.

Next, the tank 131, which is formed integrally with the inner panel 112 and is configured to surround the motor 21 of the wiper device 20, will be explained based on FIGS. 5 to 7. FIG. 5 is a central longitudinal sectional perspective view of a portion where the tank 131 is arranged, FIG. 6 is a side view of the same, and FIG. 7 is a plan view of the same.

The upper and rear surfaces of the tank 131 are the inner panel 1
12, the motor 21 of the wiper device 20 is surrounded and covered by an inner panel 112 above and by a tank 131 at the rear, below and on both left and right sides.

That is, in the inner panel 112 that is integrally molded with the tank 131, a recess 117 for storing small items is formed to be long in the left and right direction, and the front center part 118 of the panel 112 covers the motor 21 from above, It is stored in a storage recess 134 formed in the section.

The storage recess 134 has a back wall 135 and a lower wall 136.
and left and right side walls 137, 137, and a washer liquid chamber W is formed on the back side of these back wall 135, lower wall 136, and both side walls 137.

Since the washer fluid chamber W is located around the motor 21 so as to surround it from behind, from below, and from both sides, in addition to the above-mentioned effects, it is possible to exhibit an effective soundproofing effect against motor noise. It is also possible to have a cooling effect on the heat generated by the motor 21.

Since the inner panel 112 has a closed cross-sectional shape by integrally molding with the tank 131, the rigidity of the inner panel 112 is increased, and this 11
Fairing 1 assembled with 2
0, the rigidity of the connecting parts such as the windshield 11 also increases secondarily.

In addition, since the tank 131 is integrated with the inner panel 112 using the inner panel 112, only the minimum number of fasteners such as screws are required when retrofitting the washer device 30, and the work space for tools during installation is also minimized. As a result, it is possible to reduce the number of parts, make effective use of space for accessories, etc., and reduce the overall weight of the fairing system, including the equipment attached to it.

By the way, there is a washer fluid replenishment port 138 at the end of the inner panel 112 that constitutes the upper surface of the tank 131.
With this arrangement, the washer fluid can be replenished extremely easily, and maintenance efficiency is dramatically improved compared to the conventional method.

In addition, if a transparent washer fluid indicator 139 is provided at an appropriate location, such as a portion of the rear surface of the tank 131, the indicator can be installed at low cost and effectively, further improving maintainability.

Although the washer switch of the washer device 30 has not been mentioned, it may be shared with the wiper switch 25 or may be provided separately at any location.

As described above, according to the present invention, the washer liquid tank is arranged between the fairing and the handlebar, with the tank width center aligned with the vehicle width center, so that the tank and the nozzle are connected. By shortening the tube that connects the tank, it is possible to reduce costs and weight, and improve maintainability, while suppressing the effect of the tank weight on the handle operation load.
The tank capacity can be increased, and it is also advantageous in terms of preventing the vehicle body from tilting due to the weight of the washer fluid when the vehicle is parked on a slope, for example.
