ABSTRACT:
A control lever unit includes a lever, a sensor, an urging body and an elastically undeformable restricting member. The lever is pivoted tiltably from a neutral position in any direction within 360 degrees including two main operation directions and intermediate directions therebetween. The sensor detects tilt angle of the lever in the two respective main operation directions. The urging body puts the lever back to the neutral position. The restricting member has an interior wall for surrounding the lever to restrict tilting range of the lever. Contour of the interior wall of the restricting member includes 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. The main operation stop portions are positioned outside a quadrangle with the intermediate stop portions at apexes thereof.
