PROBLEM TO BE SOLVED: To provide a hybrid drive device capable of reducing vibration caused by resonance of a torsional damper without increasing the size of the hybrid drive device. SOLUTION: An annular space 83 is formed between the torsional damper 66 and an inner peripheral part of a first electric motor MG1, and a dynamic damper 67 is provided in the annular space 83. Due to this structure, the dynamic damper 67 can be arranged without increasing the size of the hybrid drive device 10. By adjusting the frequency characteristic of the dynamic damper 67 to resonance frequency fn of the torsional damper 66, vibration caused by the resonance generated in the vicinity of the frequency of fn can be reduced.
