PROBLEM TO BE SOLVED: To provide a work vehicle in which a speed changing can be performed by a simple operation and its operability or travelling performance is improved when a speed is required to temporarily change or when the speed is wanted to be a desired speed during its constant speed travel, without becoming a burden to a driver.SOLUTION: There is provided a control device 100 having an auto-cruise function for keeping a vehicle speed constant through turning-on of an auto-cruise switch 14c and a temporary speed increasing or decreasing function for increasing speed or decreasing speed only for a prescribed time by controlling a trunnion shaft driving motor for rotating a trunnion shaft of a hydraulic type stepless speed transmission device through a pushing operation within a prescribed time of a speed increasing switch 101a or a speed decreasing switch 102a at the time of auto-cruise function, so that the speed change can be temporarily performed through an easy operation and it does not become a burden to a person not familiar with the speed changing operation and its operability or its travelling performance can be improved. In addition,long-period depressing of these switches 101a, 102a enables the auto-cruise running speed to be changed to a desired speed. |
