Patent ID: 8037778

Claim:
A control lever unit comprising: a lever pivoted tiltably from a neutral position in any direction within 360 degrees including two main operation directions and intermediate directions therebetween, wherein the first main operation direction is associatable with a first operational task and the second main operation direction is associatable with a second operational task; a sensor for detecting decomposed components of a tilting angle of the lever in the two main operation directions so that the first operational task and second operational task can be performed simultaneously; an urging body for putting the lever back to the neutral position; and an elastically undeformable restricting member having an interior wall for surrounding the lever to restrict tilting range of the lever, contour of the interior wall of the restricting member including main operation stop portions for specifying tilt limit of the lever in the main operation directions and intermediate stop portions for specifying tilt limit of the lever in the intermediate directions, wherein the main operation stop portions are positioned outside a quadrangle with the intermediate stop portions at apexes thereof, wherein straight portions are arranged between each main operation stop portion and corresponding intermediate stop portions on both adjacent sides on the contour of the interior wall of the restricting member, and each straight portion extends from a main operation stop portion to an intermediate stop portion and is not parallel or orthogonal to the sides of the quadrangle.
