The present invention relates to a scooter having a posture restoration and cushioning function, and more particularly, to a scooter having a posture restoring and cushioning function that can attenuate shock while allowing stable driving even when driving or stepping on an obstacle on a road surface. It is about.

In general, a scooter with two rear wheels has a sense of stability that does not fall to the left or right side compared to a two-wheeled bicycle or a two-wheeled scooter, so anyone can easily learn and ride it. It has the advantage of being available.

However, such a scooter has a problem that both rear wheels are configured to protrude outward than the front wheels can be overturned compared to two-wheeled bicycle or two-wheeled scooter.

That is, the scooter consisting of three wheels had a problem in that the rear wheel portion is biased in the direction in which the centripetal force does not return to the state of maintaining or maintaining the balance state when changing the direction during driving or passing over obstacles on the road surface.

Because of this, the general public as well as the elderly can easily learn and ride a scooter, which is an inexpensive means of transportation and transportation, was not widely spread due to the above problems.

Therefore, improvement of forward stability and rapid return of the moved center of gravity are necessary to easily drive and stably ride regardless of the traveling speed of the three-wheeled scooter, the load weight on the rear wheel, and the road condition. It is a required situation.

The present invention has been made in order to solve the above problems, and the object is to be able to quickly restore the posture even when stepping on the road or obstacles on the road by mounting the cushioning means in the front and rear.

In addition, the purpose is to minimize the impact transmitted on the road surface while the shock absorbing means is mounted on the front and rear.
