Description

[Detailed Description of the Invention] Some scooters had a front shield that was divided into two parts, an upper and a lower part, but in such a case, the structure was complicated and the number of parts was large because the two parts were joined together. , the number of man-hours for processing and assembly were large.

In addition, the front fender, which is integrated with the front fork that pivots the front wheel so that it can freely turn, extends downward from the rear of the front wheel, and the front shield is spaced apart from the front fender so as not to interfere with the turning of the front fender. Because of this, the front edge of the floor receded, which resulted in the inconvenience that the overall length of the vehicle body became longer due to the need to ensure enough space to rest one's feet on the floor.

The present invention relates to an improvement of a front shield device for a scooter that eliminates these inconveniences.The purpose of the present invention is to shorten the overall length of the vehicle body while having a simple structure, low cost, and a constant footrest surface. The aim is to provide a compact scooter that can
