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).

Abstract: A power transmitting apparatus inputs or cuts off rotational power of an input member (1) to an output member (3) by press-contacting a plurality of driving-side clutch discs (6) and a plurality of driven-side clutch discs (7) with each other or releases them. A clutch housing (2) includes the driving-side clutch discs (6). A clutch member is (4) connected to the output member (3). A pressure member (5) press-contacts the discs (6) and discs (7) with each other or releases the press-contacting force between them. Application of a resisting force, for resisting relative rotation between the clutch member (4) and the pressure member (5), can be attained. A magnitude of the resisting force is set larger than a sticking torque between the discs (6) and discs (7).
