Abstract: There is provided a work vehicle in which sudden operation of a work implement can be suppressed. The work vehicle includes a design surface information acquiring unit for acquiring data of a design surface indicative of a target shape of a work object by the work implement; a cutting edge position computing unit for computing a position of a cutting edge of a bucket; and an operation restricting unit for executing operation restriction control by which a boom is forcibly raised in accordance with a relative position of the cutting edge to the design surface, and the position of the cutting edge is restricted to an upper part of the design surface. In a state where the cutting edge is located away from the design surface in a downward perpendicular direction by a prescribed distance or longer, the operation restricting unit does not execute the operation restriction control.
