Abstract
A hybrid vehicle drive device includes a planetary gear mechanism, a one way clutch, and a torque limiter, wherein a sun gear of the planetary gear mechanism is connected to a first electric rotating machine, a carrier thereof is connected to an engine, and a ring gear thereof is connected to a second electric rotating machine and drive wheels, respectively, the ring gear is disposed on an inner peripheral side of a hollow rotary member as well as connected to drive wheels via counter drive gear disposed on an outer peripheral side of the rotary member, the one way clutch regulates a rotation of the carrier in a negative direction when it is assumed that a rotation direction of the ring gear at the time a hybrid vehicle travels forward is a positive direction, the torque limiter operates in response to transmission torque of the one way clutch and restricts the transmission torque of the one way clutch, and the one way clutch and the torque limiter are disposed inside of the rotary member.
