<p>An operation lever lock device reliably prevents unintended movement of a fork without obstructing a forward field of view. The valve input section (22) of a hydraulic control valve (20) disposed below a floor panel (FL) and a corresponding operation lever (10) are coordinated with each other by a link member (60), and a hydraulic control valve (20) is moved by moving the link member (60) in the vertical direction through the operation lever (10). An operation lever lock device is provided with: an engagement member (70) below the link member (60) and a floor panel (FL); and a stopper plate (80). The stopper plate (80) is disposed so as to be capable of moving between an engaged position at which an engagement section (83) engages with the engagement member (70) and a disengaged position at which the engagement section (83) is disengaged from the engagement member (70). When the stopper plate (80) is disposed at the engaged position, the stopper plate (80) prevents the link member (60) from moving in the vertical direction.</p> |
