Abstract

The utility model relates to a three-wheel running vehicle which is characterized in that one work position of a backrest rod (8) is forward inclined; another work position of the backrest rod (8) is backward inclined; a front-direction seat is arranged on a lower connection rod (4); a back-direction seat rod (10) is also arranged on the connection rod (4); a back-direction seat rod (10) is provided with a back-direction seat. The back rest rod can be inclined to two directions and the lower connection rod is respectively provided with the front-direction seat and the back-direction seat so that an infant can face forward or backward to seat.
