A hybrid powered vehicle is capable of running forward and backward under various conditions (e.g., by a motor) and enables the regeneration of energy during the reduction of speed without increasing the full length, weight, cost and the like of a transmission. The hybrid powered vehicle has a planetary gear unit, which comprises the following three elements: a ring gear, a sun gear, and a carrier pivotally supporting a planetary pinion arranged between the carrier and the sun gear. The planetary gear unit is disposed between an engine and an electric motor. The hybrid powered vehicle also has a forward/backward rotation switching mechanism, which comprises a brake for braking a first element that is one of the above-mentioned three elements and a clutch for connecting and disconnecting two elements among the above-mentioned three elements. An output shaft of the engine connects to one of the two elements other than the first element, and an output shaft of the electric motor and an input shaft of the transmission connect to the other.
