(Effects of the Invention) As described above, according to the present invention, the intermediate plate can be securely held at the predetermined return position to prevent the clutch from being disengaged, and the mounting position of the stopper member with respect to the input side rotating member can be adjusted so that the clutch disc is not worn. Following this, the cutting margin of the intermediate plate can be automatically adjusted so as to be always constant, and the impact force of the intermediate plate can be alleviated, and the impact wear between the stopper member and the intermediate plate can be prevented.
