摘要:
A hand lever apparatus (throttle lever) (10) is provided which has an automatic restoring function (automatic idle rotation opening position restoring function) to cope with an accident and which can perform normal operation lightly and swiftly. The hand lever apparatus (10) has a rotationally operable operating lever (30) and a toggle mechanism (T). The operating lever (30) is operated to actuate, through the toggle mechanism (T), a cable (20) connected to a driven member (CV) so as to pull the cable (20).

A hand lever apparatus (throttle lever) is provided which has the automatic restoring function (automatic idle rotation opening position restoring function) to cope with accidents and steadily hold a desired operation position (intermediate opening position of a throttle valve). The hand lever apparatus has a rotationally operable main lever (30) and a sub-lever (40) rotationally operated to pull a cable (10a) connected to a driven member (CV). The main lever (30) has a brake plate (34). By pressing the brake plate (34) against an operating portion (42) of the sub-lever (40), rotation of the sub-lever (40) is regulated to hold the sub-lever (40) in a position.
摘要:
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).
