する、 作業車輌におけるレバー装置。[Claims for Utility Model Registration] An operating lever is installed so as to be tiltable in one direction and the other direction, and the operating angle of the lever is detected by an operating angle detection means, and the preprocessing section is activated based on the detected value of the detection means. A work vehicle configured to move up and down, comprising: a changeover switch capable of switching to at least three positions; a detected value determining means for determining whether a detected value of the operating angle detecting means is normal or abnormal; and an abnormality of the detected value determining means. A lever device for a work vehicle, characterized in that the lever device is provided with a switching means for switching from pre-processing section elevating control based on the value of the operation angle detecting means to pre-processing section elevating control using the changeover switch, based on a determination of the value. .
