A driving force transmission system comprising: a coupling case and a shaft arranged rotatably relative to each other; a pilot clutch and a main clutch for controlling a torque transmission between the coupling case and the shaft; an electromagnet for controlling the actions of the pilot clutch and the main clutch; and oil retaining the functions of the pilot clutch and the main clutch. This system further comprises a coupling case, a shaft, a rotor, and X-ring and an O-ring isolating a coupling oil chamber, in which the pilot clutch and the main clutch are arranged, liquid-tight from the surrounding space.

There is disclosed a drive force transmission apparatus which includes a first pressing-force generation unit for generating a pressing force in accordance with a rotational speed difference between driving and driven shafts, and a frictional clutch which is brought into an engaged state by the pressing force generated by the first pressing-force generation unit in order to transmit torque in accordance with the rotational speed difference between the driving and driven shafts. The drive force transmission apparatus further includes a second pressing-force generation unit disposed opposite to the first pressing-force generation unit with respect to the frictional clutch. When needed, the second pressing-force generation, unit is operated to bring the frictional clutch into a firmly engaged state, thereby improving the traveling performance of the vehicle under severe traveling conditions, such as an attempt to extract a wheel trapped in a gutter or the like, traveling on a rough road, traveling on sand, etc.
