ABSTRACT:
A hand lever device is disclosed which is adapted so that a throttle valve as a driven member can be adjusted appropriately in its degree of opening via a cable and kept at a desired degree of opening and yet immediately returned to the minimum degree of opening to ensure high safety. Thus, fatigue of an operator's fingers can be diminished. Also, the throttle valve is enabled to be brought to the degree of opening at which it had stood before it was returned to the minimum degree of opening without the necessity of readjustment. The hand lever device comprises an eccentric cam shaft (40) including a supporting shaft portion (42) and a pivot pin portion (41, 43) having pivotal axis (0b) eccentric to axis (0a) of the supporting shaft portion (42), a main lever (30) pivotally fitted on the supporting shaft portion (42), and a sub-lever (50) fixed to the pivot pin portion (41). The main lever (30) and sub-lever (50) are pivotally operated to draw a cable (20) connected to a driven member (CV).
