Claims

[Scope of utility model registration request]

A clutch plate having an annular facing provided on its outer periphery, a retaining plate that is integrally connected to the clutch plate parallel to the clutch plate, and a retaining plate that is connected between the retaining plate and the clutch plate. A hub plate is interposed so as to be relatively rotatable, and a relative rotation range of the hub plate comes into contact with a locking part that is provided integrally with the clutch plate and the retaining plate and is formed on the hub plate. a first torsion spring with a small spring constant that is tightly housed in a first window formed in the hub plate and that locks on both sides of the clutch plate and the retaining plate, respectively; , a second torsion spring with a large spring constant that is loosely fitted into a second window formed in the hub plate and locks on both sides of the clutch plate and the retaining plate, respectively; and a friction lever having a pair of gripping claws formed at the distal end thereof, the gripping claws being fitted in the second window portion so as to be relatively rotatable and positioned in the second window portion and facing each other so as to sandwich the second torsion spring from both sides. A clutch disc for an automobile, characterized in that an interval between the gripping claws of the friction lever is set to be larger than a free length of the second torsion spring.
