PCT No. PCT/JP91/00123 Sec. 371 Date Sep. 30, 1991 Sec. 102(e) Date Sep. 30, 1991 PCT Filed Jan. 31, 1991 PCT Pub. No. WO91/11817 PCT Pub. Date Aug. 8, 1991.An operating lever device constructed such that the members thereof having a comparatively high rigidity can be used in such a way as to minimize the wear-down thereof and enable the angle of inclination of the lever to be detected precisely over a long period of time. The operating lever device is arranged such that any one of a plurality of rod members (22) which are inserted slidably while they are constantly urged upward into the device body (10) can be pushed down by the tilting of a lever (20) so as to rotate either a first shaft (23) or a second shaft (24) through a retaining member (27) or (28) held in contact with the lower end of the rod member (22). Thus, the angle of inclination of the lever (20) can be detected precisely by either one of rotational angle sensors (25, 26) mounted on at least one end of each of the first and second shafts.
