Abstract
A power transmission device for a four-wheel drive vehicle having a power source and first and second drivelines includes an input shaft adapted to be driven by the power source. A first output shaft is rotatable about a first axis and adapted to transmit torque to the first driveline. A second output shaft is adapted to transmit torque to the second driveline and is rotatable about a second axis. The first and second axes do not extend parallel to each other. A transfer unit includes a first cylindrically-shaped gear rotatably supported on the first output shaft and a second conically-shaped gear fixed for rotation with the second output shaft. The first and second gears are in constant meshed engagement with each other.
