Abstract
A hand lever device for operating a driven member includes a main lever arranged to be pivoted about a first rotational axis, a sub-lever arranged to be pivoted about a second rotational axis and retained in a stationary state at a set pivoted position, a returning member arranged to be rotated about a third rotational axis, and a cable coupled at one end to the driven member and linked at the other end with the main lever and the returning member. When the main lever is pivoted to a set position, it rotates the returning member about the third rotational axis and removes slack from the cable. Pivoting of the sub-lever further rotates the returning member about the third rotational axis to a selected operating position. An accelerating subsidiary lever that is also pivoted about the first rotational axis further pulls, via the returning member, the cable, thereby to further move the driven member.
