Claims

[Scope of utility model registration request]

a flywheel assembly having a clutch cover fixed to the flywheel; and a flywheel assembly coupled to the flywheel assembly via a first elastic strap so as to be non-rotatably and axially movable relative to the clutch cover and the flywheel. a pressure plate located between the flywheel assembly, and a second elastic strap connected to the flywheel assembly so as to be non-rotatable and movable in the axial direction and located between the pressure plate and the flywheel. a first clutch disk located between the pressure plate and the middle plate, and a second clutch disk located between the middle plate and the flywheel; The first elastic strap biases the pressure plate toward the clutch cover, and the second elastic strap biases the intermediate plate toward the pressure plate. In,
forming an axial through hole in the outer periphery of the intermediate plate, and slidably fitting a cylindrical body whose end face on the flywheel side is closed by a closing part into the through hole;
An axial hole is formed in the closed portion of the cylindrical body, and a positioning member is provided that slidably passes through the hole and whose end surface on the pressure plate side abuts the outer peripheral portion of the pressure plate; This positioning member has
a first large diameter portion located closer to the pressure plate than the closing portion of the cylindrical body and having a larger diameter than the hole of the closing portion; and a first large diameter portion located closer to the flywheel than the closing portion of the cylindrical body. a second large-diameter portion located at the cylindrical body and having a larger diameter than the hole of the closing portion, and between the closing portion of the cylindrical body and the first large-diameter portion of the positioning member A spring that biases the positioning member in a direction to separate them from each other is interposed to apply a force required for sliding the cylindrical body to the pressure plate that is greater than the biasing force of the second elastic strap. Set it smaller than the pressing force for connecting the clutch.
Clutch cover assembly for a twin clutch, characterized in that the biasing force of the spring is set larger than the biasing force of the second elastic strap.
