The console box is configured to be rotatable in a forth and back direction. The support rotatably supports the console box around the rotational axis and between an operating position in which the console box is horizontally disposed and a retracted position in which the console box is inclined at a position in which the console box has been rotated rearward from the operating position. A spacing in a horizontal direction between front and rear ends of the console box disposed in the retracted position is less than a spacing in the horizontal direction between front and rear ends of the console box disposed in the operating position. ## Claims ### Claim 1 A work vehicle, comprising: a console box disposed to a side of an operator's seat, the console box being configured to be rotatable in a forth and back direction; and a support including a rotational axis disposed in a left and right direction below the console box, the support rotatably supporting the console box around the rotational axis and between an operating position and a retracted position in which the console box has been rotated from the operating position, a spacing in a horizontal direction between front and rear ends of the console box disposed in the retracted position being less than a spacing in the horizontal direction between front and rear ends of the console box disposed in the operating position the rotational axis is disposed ahead of a center in the forth and back direction of the console box disposed in the operating position. ### Claim 2 (depends on 1) The work vehicle according to claim 1, wherein the console box is horizontally disposed when the console box is in the operating position, and the console box is rotated rearward so as to be inclined when the console box is in the retracted position. ### Claim 3 A work vehicle, comprising: a console box disposed to a side of an operator's seat, the console box being configured to be rotatable in a forth and back direction; a support including a rotational axis disposed in a left and right direction below the console box, the support rotatably supporting the console box around the rotational axis and between an operating position in which the console box is horizontally disposed and a retracted position in which the console box is inclined at a position in which the console box has been rotated rearward from the operating position; an operation member disposed on an upper side near the front end of the console box; and a transmission component disposed facing a floor of the operator's seat from a lower side near the front end of the console box, the transmission component being configured to transmit an operation of the operation member to an operational object to be operated, a spacing in a horizontal direction between front and rear ends of the console box disposed in the retracted position being less than a spacing in the horizontal direction between front and rear ends of the console box disposed in the operating position, the transmission component telescoping in and out along with rotation of the console box from the operating position to the retracted position, while rotating with an end of the transmission component on a floor side acting as a fulcrum. ### Claim 4 (depends on 3) The work vehicle according to claim 3, wherein the rotational axis is disposed within a rotation range of the transmission component as viewed in side view. ### Claim 5 (depends on 3) The work vehicle according to claim 3, wherein in a state in which the console box is disposed in the operating position, the transmission component is disposed in front of the rotational axis. ### Claim 6 (depends on 3) The work vehicle according to claim 3, further comprising: a front frame; a rear frame; a hydraulic actuator disposed from the front frame to the rear frame, the hydraulic actuator being configured to change a steering angle of the front frame with respect to the rear frame; and a control valve configured to control fluid supplied to the hydraulic actuator, the operation member being a joystick lever, and the operational object being the control valve.
