Field of the invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a radar shield attached to both front sides of a body frame of a motorcycle so as to cover legs of an occupant sitting on a seat.

Background art

Conventionally, on motorcycles such as the one-wheeled scooter type, leg shields that cover the occupant's legs are installed on both sides of the front of the body frame to prevent rain or wind from directly hitting the occupant's legs while driving. (See Japanese Patent Application Laid-Open No. 10-16851).

By the way, conventional redder shields are made of plate members such as synthetic resin plates and metal plates.However, they are required to have the desired strength and to be able to accurately respond to the mounting part of the body frame. Functional requirements necessitate that the shield itself be designed in a complex shape, rather limiting the external shape and not giving sufficient consideration to the external shape with aesthetic appearance. However, there is a problem that it is difficult to design a desired shape in appearance, and the complicated shape makes it difficult to paint. There is another problem that the tendency increases, leading to higher costs and lowering the quality.

In addition, this type of motorcycle may be used with the red shield removed depending on the region or season.In this case, the attachment and detachment of the conventional motorcycle to and from the vehicle is complicated. In addition, when the redder shield was removed, there was a further problem that a gap was formed in the motorcycle body, and the interior became visible through the gap, resulting in a bad appearance.
