PROBLEM TO BE SOLVED: To provide a driving force transmission device capable of suppressing the occurrence of abnormal noise during reversing the direction of torque transmission between an outside rotary member and an inside rotary member even if more rotational looseness exists between the outside rotary member and an outside clutch plate.SOLUTION: A driving force transmission device 2 includes a housing 20 and an inner shaft 23 arranged in a coaxial manner, a main clutch 3 consisting of a plurality of main outer clutch plates 31 and a plurality of main inner clutch plates 32, and a cam mechanism 4 for imparting thrust force to the main clutch 3, the housing 20 having a plurality of outer periphery spline projections 211 on the inner peripheral face, the main outer clutch plates 31 each having a plurality of engaging projections 311 at the outer peripheral end for loosely engaging with the plurality of outer periphery spline projections 211. It further includes a friction member 6 for slide contact with the inner peripheral face of the housing 20 to generate frictional resistance force when the main outer clutch plates 31 are rotated relative to the housing 20 within the range of looseness.SELECTED DRAWING: Figure 4

    【課題】外側回転部材と外側クラッチプレートとの回転ガタ量を大きくしたとしても、外側回転部材と内側回転部材との間のトルク伝達方向が反転した際の異音の発生を抑制することが可能な駆動力伝達装置を提供する。【解決手段】同軸上に配置されたハウジング20及びインナシャフト23と、複数のメインアウタクラッチプレート31及びメインインナクラッチプレート32からなるメインクラッチ3と、メインクラッチ3に押圧力を付与するカム機構4とを備えた駆動力伝達装置2において、ハウジング20は、複数の外周スプライン突起211を内周面に有し、メインアウタクラッチプレート31は、複数の外周スプライン突起211にガタをもって係合する複数の係合突起311を外周端部に有し、メインアウタクラッチプレート31がガタの範囲内でハウジング20に対して回転する際にハウジング20の内周面に摺接して摩擦抵抗力を発生させる摩擦部材6を備える。【選択図】図4
