Title:
OPERATING LEVER DEVICE
Document Type and Number:
WIPO Patent Application WO/1991/011817
Kind Code:
A1
Abstract:
An operating lever device capable of detecting an inclination angle of the lever for a long time with high precision owing to the provision of a structure in which component members relatively high in stiffness can be used under low-wear conditions. In this operating lever device, any one of a plurality of rods (22) slidably inserted into a device proper (10) and constantly energized upward is depressed in accordance with inclining motion of the lever (20) and turns a first or second shaft (23 or 24) through receiving members (27, 28) which are in contact with the lower end of the rod (22). Thus, an inclination angle of the lever (20) is detected with high precision by means of rotation angle sensors (25, 26) disposed at at least one end of the first and second shafts thereof, respectively.
