PROBLEM TO BE SOLVED: To provide a clutch device and a driving power transmission device capable of suppressing increase of the number of components and assembling man-hours, and reducing drag torque while securing durability of a clutch plate.SOLUTION: A clutch device 2 includes a front housing 21 and a pilot cam 61 relatively rotatable on a common rotation axis O, an outer clutch plate 41 engaged axially movably and relatively non-rotatably to the front housing 21, an inner clutch plate 42 engaged axially movably and relatively non-rotatably to the pilot cam 61, and a pressing mechanism 5 generating pressing force so that the outer clutch plate 41 and the inner clutch plate 42 are frictionally kept into contact with each other. A spline engagement portion 611 with the inner clutch plate 42, of the pilot cam 61 is inclined to the rotation axis O so that the inner clutch plate 42 is inclined to the outer clutch plate 41.SELECTED DRAWING: Figure 5 |
