<p>PROBLEM TO BE SOLVED: To provide a drive device for a hybrid vehicle with the driving gear chamber pinched by a clutch chamber and motor chamber well lubricated using a less number of oil seals involving a low friction loss and assuring easy maintenance. SOLUTION: A concentrical double shaft structure is introduced in which an inner rotor shaft 7 coupled with an inner rotor 6 of a multi-layer motor 14 penetrates a hollow outer rotor shaft 9 coupled with an outer rotor 8, wherein the inner rotor shaft 7 is coupled with the engine output shaft 10, and a driving gear 11 is provided on the outer rotor shaft 9 penetrating a driving gear chamber 3, and a clutch chamber 2 and motor chamber 4 partitioned on the sides of the driving gear chamber 3 are put in mutual communication through a shaft space 12 formed between the inner rotor shaft 7 and outer rotor shaft 9.</p> |
