Claim:
1. A power take-off unit adapted to take-off power from a transmission for driving first drive wheels of a vehicle and to transmit the taken-off power to second drive wheels of the vehicle, the power take-off unit comprising: a power take-off casing mounted directly on another casing incorporating the transmission; a power take-off shaft journalled by the power take-off casing, drivingly connected to a transmission shaft of the transmission and drivingly connected to the second drive wheel; and a brake disposed in the power take-off casing, wherein the brake includes an unslidable pawl that is fixed to the power take-off casing so as to be unslidable in the axial direction of the power take-off shaft, and wherein the brake includes a slidable pawl that is slidable axially in the axial direction of the power take-off shaft so as to be shiftable between a braking position where the slidable pawl engages with the unslidable pawl so as to brake the power take-off shaft and an unbraking position where the slidable pawl disengages from the unslidable pawl so as to unbrake the power take-off shaft, wherein when the slidable pawl engages with the unslidable pawl the brake applies braking force to both the first drive wheel and the second drive wheel.
