Abstract

This invention provides an obstacle auxiliary wheel comprising a front fork combination having a wheel base and a vertical spool pipe set on top of the wheel base vertically. A main wheel is pivoted in the wheel base, and guiding wheels are pivoted on two sides of the front end of the wheel base symmetrically, each guiding wheel is smaller than the main wheel and overlapping to the main wheel partially. When using this invention, the obstacle auxiliary wheel is pivoted on the front side of transportation such as wheelchair. While climbing a stairway, the higher guiding wheels climb the stairs first and heave height, than the main wheel continuously climbs the stairs. For the above, the obstacle passing effect can be achieved. Further, the each guiding wheel of this invention can be set as axis position and overlap to the main wheel partially, thus the length can be decreased effectively for preventing the footrest of the wheelchair from tripping during turn round. The wheelchair is practical utility and low cost.
