A power transmission unit that can prevent application of excessive torque to the powertrain is provided. The power transmission unit comprises a transmission (4) configured to transmit torque between an engine (1) and drive wheels (6); a locking device (23) configured to selectively halt a rotation of an output shaft (1a) of the engine (1); a transmission case (25) which holds a first motor (2), a second motor (3), the transmission (4), and the locking device (23); a first torque limiter (13) disposed between the engine (1) and the locking device (23) to restrict torque transmitted between the drive wheels (6) and the engine (1); and a second torque limiter (24) held in the transmission case (25) to restrict torque transmitted between the drive wheels (6) and the locking device (23).
