PROBLEM TO BE SOLVED: To provide a driving force transmission device capable of being miniaturized as a whole in a radial direction without shortening a radial dimension of a second clutch.SOLUTION: A driving force transmission device 1 includes: a cam mechanism 15 having a pilot cam 150 for converting a torque from a housing 12 by an operation by a clutch motion of a pilot clutch 10 into cam thrust P, and rotated by receiving the torque of the housing 12 from the pilot clutch 10 and a main cam 151 for applying the cam thrust P to a main clutch 8 as pressing force; and a reaction force receiving member 16 receiving reaction force acting by generation of the cam thrust P from a pilot cam 150 side of the cam mechanism 15 to a pilot clutch 10 side, and disposed between the main clutch 8 and the pilot cam 150. |
