PROBLEM TO BE SOLVED: To reduce an interval between opposed cam faces.SOLUTION: A clutch center 5 is disposed outside of a pressure plate 4 in an axial direction. A lifter plate 3 is disposed outside of the clutch center 5 in the axial direction. The lifter plate 3 is constituted to be rotated integrally with the pressure plate 4. A cam mechanism 7 makes the lifter plate 3 and the clutch center 5 separate from each other in the axial direction when the lifter plate 3 and the clutch center 5 are relatively rotated. First and second cam faces 711, 712 are formed on the lifter plate 3. Third and forth cam faces 721, 722 are formed on the clutch center 5. The first and second cam faces are inclined so that they are directed to the inside in an axial direction, and directed oppositely to each other in the circumferential direction. The third cam face is opposed to the first cam face, and the forth cam face is opposed to the second cam face.SELECTED DRAWING: Figure 2 |
