Abstract
A clutch-brake device is provided on a driving force delivery system delivering a driving force, inputted to a fly wheel of a mechanical press, to a crank shaft. A stationary member rotationally supports the fly wheel. A rotation shaft has at least one part rotationally supported by the stationary member and transfers the driving force to the crank shaft. A multi-disk clutch is provided between a case member affixed to the fly wheel and a rotation input part of the rotation shaft. A multi-disk brake is provided between the stationary member and the rotation input part of the rotation shaft. A fluid pressure cylinder rotates as a unit with the fly wheel and switching the multi-disk clutch and the multi-disk brake. An output part, on the piston member of the fluid pressure cylinder, delivers the pushing force of the piston member to a clutch plate which rotates as a unit with the case member. The clutch-brake device prevents abrasion of the piston member and the like, increases durability, reduces manufacturing costs, and prevents looseness of the piston member.
