Abstract
An object of the invention is to suppress an increase in an inner diameter of a friction facing of a clutch disk assembly, which may be caused by fixing portions of a plate member pair of a clutch disk assembly 1. The clutch disk assembly 1 is provided to couple to a flywheel 2 of an engine. The clutch disk assembly 1 includes a friction facing 20, a pair of plates 15 and 16, a hub 8, and coil springs 11. The plates 15 and 16 have fixing portions 34 fixing their outer peripheral portions together. The coil springs elastically couple the paired plates 15 and 16 to the hub 8 in the rotating direction. The fixing portions 34 project radially outward beyond the inner periphery of the friction facing 20.
Claims20
A clutch disk assembly being configured to be coupled to a flywheel of an engine, said clutch disk assembly comprising:
- a friction facing being arranged near the flywheel;
- a pair of plate members being axially spaced from each other and having fixing portions to fix radially outer portions of said plate members together, said fixing portions being configured to extend radially outside of an inner periphery of said friction facing;
- a hub;
- and
- an elastic member being configured to couple elastically in a rotating direction said pair of plate members to said hub.
