<p>PROBLEM TO BE SOLVED: To provide a driving force transmission device capable of suppressing the occurrence of abnormal sounds while suppressing a reduction in the responsiveness and torque transmission capacity of a clutch.SOLUTION: A driving force transmission device 1R includes a housing 2 and an inner shaft 3 relatively rotatable coaxially with each other, a main clutch 4 having a main outer clutch plate 41 spline-engaging with the housing 2 and a main inner clutch plate 40 spline-engaging with the inner shaft 3, and adapted to be subjected to axial thrust to connect the inner shaft 3 and the housing 2 in a torque transmissive manner, a pilot clutch 5 to be subjected to the rotating force of the housing 2, a cam mechanism 7 having a pilot cam 71 to be subjected to rotating force transmitted by the pilot clutch 5 and a main cam 70 to be rotated relatively to the pilot cam 71 to convert the rotating force into axial thrust on the main clutch 4, and a pushing member 12 for pushing the main cam 70 to be isolated from the main clutch 4.</p> |
