Abstract:
1. A power output apparatus that outputs power to a drive shaft, said power output apparatus comprising: a power generation source that can output power to a predetermined rotational element; a continuously variable transmission device that can steplessly change the speed of power inputted to an input shaft and output the power to an output shaft; a planetary gear mechanism including a first input element connected to said output shaft of said continuously variable transmission device, a second input element that can rotate in a direction opposite to a rotational direction of said rotational element in conjunction with said rotational element, and an output element connected to said drive shaft; a connection and disconnection device that connects and disconnects said rotational element to and from said input shaft of said continuously variable transmission device; an electric motor that can output at least power to said input shaft of said continuously variable transmission device; and an accumulator that can supply and receive electric power to and from said electric motor.
