Abstract
In order to eliminate noise generated from a clutch disk at racing state of a press, a clutch disk (29) arranged between a flywheel (27) and a working cylinder (40) is provided with a lining applying part (30) of annular shape and a projection (31) mounted on the flywheel (27). On inner circumferential surface of the projection (31), an inner groove part (311) is formed throughout the whole circumference from the inner circumferential edge to the outer circumferential edge in the circumferential direction, and on outer circumferential surface of the projection (31), an outer groove part (312) is formed throughout the whole circumference in the circumferential direction. Thereby the clutch disk (29) has flexibility in the axial direction, and if the lining applying part (30) is pushed by the working cylinder (40), the clutch disk (29) pushes a clutch rotary plate (34) by deflection of the projection (31) in the axial direction and rotates a crank shaft (25).
