ABSTRACT:
A twin-plate clutch comprises an annular intermediate plate interposed between a fly wheel and a pressure plate, a first clutch disc interposed between the intermediate plate and the fly wheel, and a second clutch disc interposed between the intermediate plate and the pressure plate, wherein the first clutch disc is provided with facings fixed to an outer circumferential portion of a disc plate thereof under a condition of no cushioning function in an axial direction of the first clutch disc, and the second clutch disc is provided with cushion springs fixed to an outer circumferential portion of a disc plate thereof and facings fixed on both sides of the cushion springs. With this arrangement, an amount of axial movement of the second clutch disc of the twin-plate clutch is rendered small, thereby suppressing increase in a pedal stroke and reducing wear between a clutch hub of the second clutch disc and an input shaft. Further, it is possible to easily carry out semi-engagement operation of the clutch owing to the provision of cushioning function in an axial direction of the second clutch disc.
