摘要： PROBLEM TO BE SOLVED: To provide a clutch device capable of improving responsiveness of clutch engagement regardless of friction between a clutch plate and a rotary member, and improve hysteresis in generated torque characteristics to operation force.
SOLUTION: This clutch comprises a pair of rotary members 1 and 6 which make differential rotation, and a pair of plates 8B and 8A alternately disposed to corotate. In at least one plate 8A of the plates, a deformation promoting part 9 is formed. Even when slide resistance is generated between the clutch plate 8A and the rotary member 6, friction slide surfaces are able to start getting in contact without being troubled by that. Delay at the time of engagement is eliminated to improve responsiveness, and enable quick clutch engagement. Hysteresis in generated torque characteristics to operation force is also improved.
