Description

[Detailed Description of the Invention] For example, in a motorcycle with a floor called a scooter (there are also three-wheeled motorcycles with a front wheel and two rear wheels), the front shield is sometimes divided into upper and lower halves. However, in such a device, since the two parts are joined, the structure is complicated, the number of parts is large, and the number of processing and assembly steps is large.

In addition, the front fender, which is integrated with the front fork that pivots the front wheel so that it can pivot freely, extends downward from the side of the front wheel.
Because the front shield is formed at a distance from the front fender so as not to interfere with the turning of the front fender, the front edge of the floor is set back, and the overall length of the vehicle is longer due to the need to ensure space for placing the object on the floor. There was some inconvenience.

The present invention relates to an improvement of a front shield device for motorcycles, etc. that eliminates such inconveniences, and its purpose is to have a simple structure, low cost, and a device that extends the entire length of the vehicle body while having a constant footrest surface.
