Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cowling for a two-wheeled motor vehicle that covers a steering wheel, and particularly to a mounting structure for attaching a rearview mirror to the cowling.

In recent years, there has been a trend of equipping Yari-san Kame cars for general driving with cowlings to meet external design requirements and to protect the driver from the wind and rain.

It is known that this cowling is constructed by attaching a transparent windshield that extends diagonally upwards to the slightest part around the playing card.

By the way, when attaching a rearview mirror to a motorcycle equipped with such a cowling, conventional methods have been to attach it to the lever brackets at both ends of the handlebar, or to attach it to the lower part of the windshield (on both sides of the cowl part). However, if it is attached to the handlebar, a sense of unity with the cowling will not be obtained, so in consideration of the appearance, it is preferable to attach it to the rear/f cowl part. Therefore, it is necessary to install the above-mentioned mirrors at a position where the driver can see the road without moving his/her line of sight while driving, that is, at a position approximately equivalent to the height of the windshield.
When a rearview mirror is attached to the upper cowl below the windshield, the legs that support this interface must be made longer in order to position the ground surface close to the height of the windshield. It is easy to shake due to engine vibrations, etc., and there is a risk that rearward visibility may become poor.

Furthermore, if the legs become long, the appearance will be unfavorable because it will not be possible to achieve a sense of unity with the cowling, similar to when the legs are attached to the handlebar.

The present invention was made based on these circumstances, and
The purpose of this is to make it possible to position the rearview mirror as if it were attached to the windshield, and to position the rearview mirror close to the height of the windshield. The present invention aims to provide a cowling structure for a two-wheeled motor vehicle that has less blur and improved visibility.

That is, in order to achieve the above object, the present invention overlaps the front half of the windshield on the upper surface of the cowling, and also penetrates the windshield at the rear end of the upper surface of the cowling where the windshield is overlapped. It is characterized by having a fixed lever and lever.
