Abstract

Official abstract text for this publication.

A clutch apparatus includes a clutch outer member for supporting friction discs, which are nonrotatable relative to the clutch outer member, and are axially slidable along a clutch axis; a clutch inner member for supporting clutch discs, which are nonrotatable relative to the clutch inner member, and are axially slidable along the clutch axis, and a pressure plate having a deep recess for accommodating a clutch spring engaged with the clutch inner member. The deep recess includes a bottom portion having a spring seat for receiving the clutch spring, and a partially cylindrical shape wall portion having an axis parallel to the clutch axis. The wall portion is oriented towards the clutch axis. The deep recess has a communicating portion formed therein for establishing the communication between the inner and outer surfaces of the wall portion so as to discharge oil towards the friction and clutch discs during operation.
