To provide a hybrid vehicle driving device having excellent on-vehicle property capable of setting a plurality of driving modes.
In the hybrid vehicle driving device comprising an electrode power source 2 to convert the mechanical energy with the electric power and an internal combustion engine 1 as power sources and a plurality of sets of planetary gear mechanisms 21 and 22 to control the output torque of at least one of the power sources, the electric power source 2 and the internal combustion engine 1 are connected to each other via one planetary gear mechanism 21, an output member 13 is connected to the other planetary gear mechanism 22 in which the torque output from the planetary gear mechanism 21 is input, and a means is provided, which sets at least three kinds of operational modes different in the change of the number of rotation of the output member 13 to the change of the number of rotation of the electric power source 2.
