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.
