Clutch apparatus having a vibration dampening mechanism, a reduced axial thickness and an undulated spring disposed within the vibration dampening mechanism

A clutch cover assembly connected to a flywheel and operable to engage and disengage a clutch, the clutch cover assembly and flywheel configured to rotate about a central axis, the clutch cover assembly comprising:

• a clutch cover having a radially outer portion fixed to said flywheel;
• a pressure plate disposed axially between said clutch cover and said flywheel;
• a first biasing member having an annular plate shape, said first biasing member being disposed axially between said pressure plate and said clutch cover, said first biasing member being supported by stud pins fixed to said clutch cover, said first biasing member for biasing said pressure plate toward said flywheel;
• and
• a plate member coupling said pressure plate and said clutch cover, said plate member being formed with an annular portion and a plurality of coupling portions each of which extend in a circumferential direction from a radially inner periphery of said annular portion, said coupling portions being formed integrally with said annular portion, said annular portion being fixed to said stud pins and a distal end of each of said plurality of coupling portions being fixed to corresponding radially inner portion of said pressure plate.
