<P>PROBLEM TO BE SOLVED: To provide a clutch with a torsional damper that is capable of controlling the torsional vibration of a drive shaft without causing the fixtures of a flywheel to loosen. <P>SOLUTION: The clutch 20 includes a clutch drum 32 connected to a cutting blade 3 via a drive shaft 6, and a clutch shoe 34 connected to a crankshaft 16 of an engine E and connected to the clutch drum 32 by a centrifugal force. To a flywheel 18 secured to the crankshaft 16 with a nut 19, a holder 36 is connected via a compression coil spring 50 in such a manner as to be capable of relative movement in its circumferential direction. The clutch shoe 34 is supported against the holder 36. A stopper structure 56 for transmitting the rotation force of the engine E to the holder 36 is provided between the flywheel 18 and the holder 36. <P>COPYRIGHT: (C)2013,JPO&INPIT |
