A work vehicle includes a hydraulic actuator that changes an actual steering angle, an actual steering angle detecting part, an operating unit that performs a steering operation, a relative angle detecting part, a steering control part, and a position adjustment control part. The operating unit includes an operating part, a support part, a rotating part, a biasing part biasing the operating part to a predetermined position with respect to the rotating part, and a position adjusting part that adjusts the rotating part. The relative angle detecting part detects a relative rotation angle of the operating part with respect to the rotating part. The steering control part controls the hydraulic actuator based on a rotation operation of the operating part. The position adjustment control part sets a torque based on the relative rotation angle and uses the torque to control the position adjusting part based on the actual steering angle.

An operation device has a first displacement portion that is displaceable by being operated by an occupant of a vehicle, and a second displacement portion that is supported at the first displacement portion and that is displaceable with respect to the first displacement portion by being operated by an occupant of the vehicle. Further, the operation device has a first locking portion and a second locking portion that, at a time when a mode of the vehicle is a first mode, permit displacement of the first displacement portion and restrict displacement of the second displacement portion with respect to the first displacement portion, and, at a time when the mode of the vehicle is a second mode, restrict displacement of the first displacement portion and permit displacement of the second displacement portion with respect to the first displacement portion.

An orthopaedic surgical instrument may include an elongated body with a proximal end and distal end. A clamp lever may be pivotally coupled to the proximal end of the elongated body. The clamp lever may be moveable between a locked position and an unlocked position. A biasing element may be configured to bias the clamp lever to the locked position.

A lever device includes a base pedestal, a movable body, a lever, a cam body having a cam groove, a guide pin, and a first biasing member. The lever is configured to swing between a push-down position at which the guide pin is arranged in the upper groove portion and a pull-up position at which the guide pin is arranged in the lower groove portion. The first biasing member has one end connected to a first connector portion provided on the base pedestal; and the other end connected to a second connector portion provided on the cam body, is arranged behind the second lateral shaft when the lever is located at the push-down position, and is arranged in front of the second lateral shaft when the lever is located at the pull-up position.

In a work vehicle, a pivot axis of an operating lever and a rotary axis of a potentiometer are located on a same axis. An interlocking mechanism includes an input part which inputs power of the operating lever following the operating lever about the pivot axis as a pivot, and an output part which is supported to a rotary operation shaft and outputs power of the input part to the rotary operation shaft. The input part and the output part are operably connected via a connecting pin.
