Abstract
A hand-lever device for a trimmer has a rotatably-operated main lever for operating a cable which is coupled to a driven member. A pulling stroke amplifying mechanism for amplifying the stroke of the cable pulled by the main lever is provided between the main lever and the cable. The pulling stroke amplifying mechanism is provided with a wire attaching portion to which a wire for pulling and releasing a cutter braking device is attached.
