A hand lever device is disclosed for adjusting the degree of openness of a throttle valve via a cable and kept at a desired opening degree and yet immediately returned to a minimum degree of opening to ensure high safety, thereby diminishing fatigue of fingers, and ensuring a desired level of operation. The hand lever device comprises a main lever (3) and a sub-lever (50) is attached to a wind-up tractive member (60) which draws a cable (20) connected to a throttle valve (CV) in such a manner that one end portion of the cable (20) is wound up thereon, and a torsion coil spring (42) is used as a brake operated by the main lever (30) for braking the wind-up tractive member (60) in order to hold the sub-lever (50) immobilized at any pivotally operated position.
A hand lever device comprising a housing, a main lever and a sub-lever pivotally attached to said housing;
A hand lever device disposed in the vicinity of a grip of a handle of a working machine comprising a rotating member driven by an internal combustion engine provided with a throttle valve, said throttle valve being biased at a degree of opening for running said engine at an idle condition so that when a throttle cable connected thereto is drawn from the idle position, the throttle valve begins to open to a greater extent,
