Zusammenfassung:To realize weight reduction of cam portions including an assist cam surface and a slipper cam surface.SOLUTION: A clutch device 10 includes a pressure plate 70, which is movable toward or away from and rotatable relative to a clutch center 40 and can press input-side rotating plates 20 and output-side rotating plates 22. The clutch center 40 includes multiple center-side cam portions 60 each having a center-side assist cam surface 60A. A center-side cam portion 60 includes at least one of: a first center-side recess 62 recessed in a first direction D1 from a surface 60D2 of the center-side cam portion 60 at the side of a second direction D2; and a second center-side recess 64 recessed in the second direction D2 from a surface 60D1 of the center-side cam portion 60 at the side of the first direction D1.SELECTED DRAWING: Figure 2 【課題】アシストカム面およびスリッパーカム面を有するカム部の軽量化を実現すること。【解決手段】クラッチ装置10は、クラッチセンタ40に対して接近または離隔可能かつ相対回転可能に設けられ、入力側回転板20および出力側回転板22を押圧可能なプレッシャプレート70を備え、クラッチセンタ40は、センタ側アシストカム面60Aを有する複数のセンタ側カム部60を備え、センタ側カム部60は、センタ側カム部60の第2の方向D2側の面60D2から第1の方向D1に凹む第1センタ側凹部62およびセンタ側カム部60の第1の方向D1側の面60D1から第2の方向D2に凹む第2センタ側凹部64の少なくとも一つを有する。【選択図】図2
