Abstract
A power transmission unit that can prevent an entrance of excessive torque to the powertrain is provided. The power transmission unit includes a transmission that transmits torque between an engine and drive wheels; a locking device that selectively halts a rotation of an output shaft of the engine; a transmission case holding a first motor, a second motor, the transmission, and the locking device; a first torque limiter disposed between the engine and the locking device to restrict torque transmitted between the drive wheels and the engine; and a second torque limiter held in the transmission case to restrict torque transmitted between the drive wheels and the locking device.
