A power output apparatus 110 includes a planetary gear 120 having a planetary carrier, a sun gear, and a ring gear, an engine 150 having a crankshaft 156 linked with the planetary carrier, a first motor MG1 attached to the sun gear, and a second motor MG2 attached to the ring gear. Part of the torque generated by the engine 150 is output to a power feed gear 128 via the ring gear, while the first motor MG1 receives the residual torque. The second motor MG2 outputs a torque having a greater magnitude than and an opposite direction to this torque, so as to rotate the ring gear reversely. The electric power consumed by the second motor MG2 is supplied by the electric power regenerated by the first motor MG1. This structure enables the power output from the engine 150 to be converted to a power of reverse direction and output to the ring gear.
