Abstract: Provided is a clutch device configured so that close contactability between a cam surface of a center clutch and a cam surface of a pressure clutch can be improved and torque transmission can be stabilized accordingly. The clutch device (100) includes a center clutch (105) and a pressure clutch (112). The center clutch (105) includes center-side cam portions (107), a pressure clutch slide portion (106), and a lifter plate slide portion (110). The pressure clutch (112) includes pressure-side cam portions (114), a lifter plate (116), and a second center clutch slide portion (113). The lifter plate (116) includes first center clutch slide portions (120). A clearance (C2) between the second center clutch slide portion (113) and the pressure clutch slide portion (106) is set greater than a clearance (C1) between the first center clutch slide portion (120) and the lifter plate slide portion (110).
