PROBLEM TO BE SOLVED: To provide a driving force transmission that can easily adjust transmission torque characteristics in a specific current region and includes an electromagnetic clutch, and provide a manufacturing method of the driving force transmission.SOLUTION: A clutch pressing member 33 of a cam mechanism 15 is formed so as to separate from a main cam 18. The clutch pressing members 33 having different axial plate thickness and end surface shape on an axial anti-main clutch side are fixed to a common main cam 18 body member provided in a common manner, by, for example, welding. The axial plate thickness of the clutch pressing member 33 is increased over the whole circumference, and thereby rigidity of the clutch pressing member 33 is increased. |
