A hybrid driving unit ( 7 ) in which a second electric motor ( 23 ) is disposed on the side closer to the front (the side closer to an internal combustion engine ( 5 )) than a first electric motor ( 20 ). A casing member ( 14 ) is formed such that an inner diameter of a part thereof in which a stator ( 28 ) of the second electric motor ( 23 ) is fixed is larger than that of a part in which a stator of the first electric motor ( 20 ) is fixed. It allows the second electric motor ( 23 ) to be constructed so as to have a large radial dimension and to that extent, allows the length thereof in the longitudinal direction to be suppressed. Accordingly, it allows the length of the whole hybrid driving unit ( 7 ) to be shortened.
