PROBLEM TO BE SOLVED: To provide a driving force transmission system capable of reducing drag torque which occurs between two adjacent clutch plates in a clutch due to the viscosity of a lubrication oil.SOLUTION: A driving force transmission system A comprises: a sub-driving source 5 which generates a motor rotation force; a first unit having a driving source housing 52 which stores the sub-driving source 5; a driving force transmission device 1 which receives the motor rotation force of the first unit to operate; and a second unit having a device case 4 for storing the driving force transmission device 1 and accumulating a lubrication oil Lq. The second unit is disposed at a position where the device case 4 makes a surface contact with the driving source housing 52. |
