Abstract: The present invention relates to a shock absorber structure of a wheelchair front fork. A front wheel of the wheelchair is coupled to a fork body at a lower end of a front fork of the wheelchair. A mandrel is installed on the front fork. The front fork includes a U-shaped body at an upper end thereof. The mandrel is connected to an upper piece of the U-shaped body. Through elastic deformation of upper and lower pieces of the U-shaped body, the vibration from the front wheel can be absorbed, providing a shock absorption effect. Compared to the shock absorption device having a spring, the present invention has a simple configuration and is compact and pleasing.
