PROBLEM TO BE SOLVED: To enhance rapid starting performance and rapid acceleration performance using driving force of internal combustion engine in a hybrid vehicle having an internal combustion engine and a generation motor as power sources for driving. SOLUTION: This planet gear mechanism 4 transmits and distributes a driving force between an internal combustion engine E, a generation motor GM and a driving wheel. The planet gear mechanism 4 comprises a planetary carrier 5 which is connected to an internal combustion engine output member 1, a ring gear 6 which is connected to a generation motor output member 2, and a sun gear 7 which is connected to a driving force output member 3. When a vehicle starts and accelerates rapidly, a clutch 9 is engaged to restrict a differential of the planet gear mechanism 4. This integrates the internal combustion engine output member 1, the generation motor output member 2, and the driving force output member 3, so that a driving force of the internal combustion engine can be transmitted directly to the driving force output member 3. |
