A position adjusting apparatus of a control console for a work vehicle in which the control console moves in a state of substantially keeping a relative position with respect to the operator seat prior to a rotation in accordance with the rotation of the operator seat, thereby maintaining a suitable operability, and a maintenance of the vehicle can be performed in an improved manner. Accordingly, a floor frame (20) and a mounting table (26) which mounts a control console (10) are connected to each other via an irregular four section link, and a turn table (12) which is rotatably supported to the floor frame or the operator seat and the mounting table are connected by an interlocking link (15). Accordingly, when an operator seat (11) which is mounted to the turn table rotates, the control console substantially maintains a relative position with respect to the operator seat before the rotation automatically, and can move in a horizontal direction.
