A control lever device for a work vehicle. The control lever device comprises a plurality of control levers to be movable along paths arranged in parallel with each other, a vertical limit member including lever openings formed therein for the plurality of control levers and extending to allow the movement of the control levers, dust-proof members movable along the back surface of the vertical limit member following the movement of the control levers to close the lever openings, lateral limit members for limiting displacement of the dust-proof members in a lateral direction relative to the moving direction of the control levers, and a base defining a movable surface for the dust-proof members. The vertical limit member and the lateral limit members are formed as a single cover to cover the dust-proof members.
