Japanese Patent No. 109186 discloses a technique relating to a front cowling in which a plurality of cowl members such as an upper panel and a middle panel are combined, and a rearview mirror cover attached to the front cowling. A cowling including a plurality of cowl members is supported by the body frame.

[0003]

The conventional cowling for motorcycles described above has a structure in which a plurality of cowl members are connected to each other, but the appearance is not good because the connecting portion is exposed to the outside. Further, in the conventional cowling, since the length of the connecting portion is long and a large number of connecting members are required, the work of connecting the cowl members to each other is complicated and the cost is disadvantageous.

The present invention has been made in view of the above circumstances, and a first object thereof is to provide a motorcycle having a cowling having a good appearance. A second object is to provide a motorcycle having a cowling whose cost is suppressed. A third object of the present invention is to provide a motorcycle having a cowling in which the cowl members can be easily connected to each other.

[0005]

In order to solve the above-mentioned problems, a motorcycle according to the present invention is a motorcycle having a cowling for covering a vehicle body, wherein the cowling is formed by coupling a plurality of cowl members. A covering member is attached to the outside of the joint between the cowl members so as to cover the joint.

According to the present invention, since the covering member for covering the joints is attached to the outside of the joints between the cowl members, the exposed portion of the joints is covered.
The appearance of the cowling is improved.

In this case, the cowling includes at least an upper cowl provided at a front end of the vehicle body and a lower cowl disposed below the upper cowl and coupled to the upper cowl. Since the rear-view mirror cover that covers the joint is attached to the outside of the joint with the cowl, the rear-view mirror cover can cover the exposed portion of the joint between the upper cowl and the lower cowl to the outside, The appearance of the cowling at the upper part of the vehicle body can be improved. Further, since the length of the connecting portion can be set short by providing the connecting portion on the upper portion of the vehicle body, the number of connecting members and the connecting points can be reduced. Therefore, it is possible to improve the coupling workability and reduce the cost.

In this case, since the upper cowl and the lower cowl are connected so as to overlap each other by a predetermined amount, the connecting action is improved.
