Abstract: Provided is a clutch device configured so that different desired torque values can be set without influence between assist torque and slipper torque. A clutch device 100 includes a center clutch 105 holding clutch plates 104 arranged facing friction plates 103 to be rotatably driven by a drive shaft, and a pressure clutch 111. The center clutch 105 includes center-side assist cam surfaces 106a and center-side slipper cam surfaces 106b. The pressure clutch 111 includes pressure-side assist cam surfaces 112a and pressure-side slipper cam surfaces 112b. A contact surface between the center-side assist cam surface 106a and the pressure-side assist cam surface 112a and a contact surface between the center-side slipper cam surface 106b and the pressure-side slipper cam surface 112b are formed at different positions in a radial direction.
