An operator seat is arranged in a cab. An air-conditioning unit is arranged in front of the operator seat. A lower window through which the outside can be seen from the inside of the cab is arranged in front of the operator seat and laterally to the air-conditioning unit.

Cab for work vehicle and work vehicle

A climbing device body () can assume by a rotation operation an erect, retracted position allowing a first end portion (A) to be positioned above and a second end portion (B) to be positioned below and a tilted, deployed position allowing the second end portion (B) to be positioned sideways of the vehicular body outer than the first end portion (A). A handrail () is engaged with the rotation operation to be capable of assuming a raised state allowing a gripping portion () to assume a first position distant from the climbing device body () in a deployed position and a folded state allowing the gripping portion () to assume a second position close to the climbing device body () in a retracted position.

Work vehicle

An operator's compartment is located above a climbing device and has a door. A sensing unit recognizes an operator. A door driving unit automatically opens the door in response the sensing unit sensing the operator.

A work vehicle includes a console box disposed to a side of an operator's seat, and a support including a rotational axis disposed in a left and right direction below the console box. 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.
