  • Patent number: 10744948
    Abstract: A climbing device body (21) can assume by a rotation operation an erect, retracted position allowing a first end portion (21A) to be positioned above and a second end portion (21B) to be positioned below and a tilted, deployed position allowing the second end portion (21B) to be positioned sideways of the vehicular body outer than the first end portion (21A). A handrail (22) is engaged with the rotation operation to be capable of assuming a raised state allowing a gripping portion (22a) to assume a first position distant from the climbing device body (21) in a deployed position and a folded state allowing the gripping portion (22a) to assume a second position close to the climbing device body (21) in a retracted position.

  • Patent number: 10370821
    Abstract: 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.
