To provide a combination clutch brake having low noise by eliminating noise to be caused by backlash of a clutch part to be connected to a driving shaft from a flywheel.

In a combination-type clutch brake provided with a piston disc 7 arranged between a clutch disc 4 and a brake disc 5, and for pressing a clutch friction plate 32 connected to a driving the flywheel 3 by releasing pressing of the brake friction plate 11 by supplying compressed air to a hollow chamber 8 between the brake disk 5 and the piston disc 7, the clutch friction plate 32 is fixed to a spring body 31, the spring body 31 is fixed to the driving flywheel 3, and backlash is eliminated from a connecting mechanism of the clutch friction plate 32 to the driving the flywheel 3.
