PROBLEM TO BE SOLVED: To provide a power transmission system capable of improving starting capability of a vehicle at a bad road and escaping capability from the bad road. SOLUTION: The power transmission system comprises a differential mechanism 43 distributing driving force of an engine 3 to left and right wheels 19 and 21, and a coupling limiting differential rotation between the wheels 19 and 21. The coupling is a rotation-sensing type or torque-sensing type differential motion limiting means, and the coupling and a connecting and disconnecting device of driving force are arranged in series between the differential mechanism and one of the left and right wheels.
