Abstract:
A portable trimmer comprising:an internal combustion engine; a cutting blade driven by said internal combustion engine; a centrifugal clutch for transmitting a driving force of said internal combustion engine to said cutting blade, said centrifugal clutch having a clutch drum; a carburetor having a throttle, a throttle operation lever for opening said throttle, a throttle wire extending between said throttle operation lever and said carburetor, a swingable member interposed in said throttle wire and being swingable in response to a pulling force of said throttle wire exerted by an operation of said throttle operation lever, said throttle wire including a first wire portion extending between said throttle operation lever and said swingable member, and a second wire portion extending between said swingable member and said carburetor to provide a first operation transmission path for transmitting the movement of said throttle operation lever to said carburetor; a brake device for braking the movement of said cutting blade, said brake device being released in conjunction with said operation of said throttle operation lever, said brake device including a friction member which is movable in response to the swing movement of said swingable member between a brake position where said friction member is pressed against said clutch drum and a release position where said friction member is spaced apart therefrom; and an additional operation lever for performing a different operation from said throttle operation, said swingable member being provided with a pulley pivotally attached thereto, said second wire portion extends between said carburetor and said additional operation lever via said pulley to provide a second operation transmission path independent from said first operation transmission path.
