DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for attaching a cowling to a motorcycle body so as to cover a front portion of the motorcycle body.

[0002]

2. Description of the Related Art In general, a cowling of a motorcycle is a molded product of a synthetic resin, and in recent years, in addition to an integral type, a cowling divided into left and right side cowls, or a left and right side cowl and a center cowl has recently been used. Some are divided into three parts. The split type cowling is usually fixed with bolts to a cowl bracket attached to a frame of a vehicle body after assembling a lap unit integrating left and right headlamps.

[0003]

However, whether the cowling is of the integral type or the split type is easily deformed at the time of mounting, it is difficult to position the mounting hole of the cowling and the screw hole of the cowl bracket. .
In particular, when the weight of the cowling is increased due to the integration of the lamp unit, the work of performing the positioning and tightening the bolts while supporting the cowling by hand is troublesome. In addition, if there is a dimensional error in the product, the work of attaching the cowling becomes more troublesome.

Therefore, in recent years, it has been practiced to attach the cowling to the cowl bracket while holding the cowling using a dedicated holding jig. However, this method of attaching a cowling not only costs extra due to the use of the holding jig, but also facilitates the work of attaching the cowling, but requires installation of the holding jig and clearing after use. It is difficult to improve the efficiency of mounting work.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a motorcycle cowling mounting structure capable of easily and quickly mounting a cowling without using a holding jig or the like. It is the purpose.

[0006]

To achieve the above object, a motorcycle cowling mounting structure according to the present invention comprises:
A mounting structure for attaching a cowling to a front portion of a vehicle body, comprising: a cowl stay connected to the vehicle body; and a substay connected to the cowl stay, wherein the cowling is mounted on the substay to form a subassembly. And the subassembly is attached to the cowl stay.

In this configuration, a sub-stay and a cowl stay corresponding to a configuration in which an existing cowl bracket is divided into two parts are provided. The cowling is attached to the vehicle body via the substay and the cowl stay by connecting the substay of the subassembly to the cowl stay. Therefore, since the rigidity of the cowling is improved by being attached to the substay, the shape is hardly changed, and the position of the cowling with respect to the cowl stay is accurately determined by attaching the substay to the cowl stay. Therefore, the work of aligning the mounting holes of the cowling with the corresponding screw holes of the vehicle body and the cowl stay can be easily performed. for that reason,
With this cowling attachment structure, the cowling can be easily and quickly attached to the vehicle body without using a holding jig or the like.

In a preferred embodiment of the present invention, the sub-stay has a mirror support for supporting a side mirror, and a cowling and a side mirror are attached to the support to constitute the sub-assembly. I have. According to this configuration, without providing a separate support portion,
The cowling can be easily attached to the sub stay using the mirror support.

Further, in a preferred embodiment of the present invention, the sub stay is connected to the cowl stay via an anti-vibration member. Thereby, even if the vibration of the vehicle body mainly composed of engine vibration is transmitted to the cowl stay connected to the vehicle body, this vibration is absorbed by the vibration isolating member and is suppressed from being transmitted to the sub stay and the cowling, and the cowling is prevented from being transmitted to the cowling. The vibration of the attached side mirror can be suppressed.

Further, in a preferred embodiment of the present invention, the sub-assembly has a headlamp unit attached to the cowling, and the headlamp is inserted into the cowl stay through an insertion hole of the headlamp unit. A positioning projection for positioning the lamp unit with respect to the cowl stay is formed. According to this configuration, the weight of the sub-assembly is increased by incorporating the headlamp unit. The assembly can be temporarily fixed to the cowl stay,
In this state, the work of connecting the sub stay to the cowl stay and the fixing of the cowling to the cowl stay can be performed easily and quickly.
