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 wheel loader representing a work vehicle includes an operator's seat, an armrest, and a seat operation portion. The armrest is provided lateral to the operator's seat. The seat operation portion controls a position or a posture of the operator's seat. The seat operation portion is attached to the armrest.

Work vehicle

A wheel loader representing a work vehicle includes an operator's seat, a console, and an armrest. The console includes an operation portion. The console is provided lateral to the operator's seat. The armrest includes an upper surface. The armrest is provided lateral to the operator's seat and in the rear of the operation portion. The armrest operates independently of the console such that a rear end of the upper surface is laterally displaced in a top view.

Each of a pair of rear side face windows of a cab extends rearward from each of a pair of rearmost pillars. A rear face window is connected to each of the pair of rear side face windows and located in the rear of the rearmost pillars. The rear face window is inclined such that an upper portion thereof is located more rearward than a lower portion thereof, and it is entirely made of glass from a first rear side face window representing one of the pair of rear side face windows to a second rear side face window representing the other of the pair of rear side face windows.

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.

A work vehicle is articulated with a front frame and a rear frame linked to the front frame. The work vehicle includes a hydraulic actuator, a control valve, an operation member and a force imparting component. The hydraulic actuator is configured to be hydraulically driven to change a steering angle of the front frame with respect to the rear frame. The control valve is configured to control flow of fluid supplied to the hydraulic actuator. The operation member is linked to the control valve and configured to be operated by an operator. The force imparting component is configured to impart an assist force or a counterforce to an operation of the operation member.

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.

A climbing device body can assume by a rotation operation an erect, retracted position allowing a first end portion to be positioned above and a second end portion to be positioned below and a tilted, deployed position allowing the second end portion to be positioned sideways of the vehicular body outer than the first end portion. 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.

A work vehicle cab includes a floor, a ceiling, a left supporting member, a right supporting member, a front panel, a front panel reinforcement member, a front-left pillar, and a front-right pillar. The ceiling is arranged above the floor. The left supporting member extends upward from the front section of the floor. The right supporting member extends upward from the front section of the floor. The front panel is arranged between the left supporting member and the right supporting member. The front panel reinforcement member, arranged above the front panel, extends in a left-right direction and connects the left supporting member and the right supporting member. The front-left pillar extends from the front section of the ceiling to the front panel reinforcement member. The front-right pillar extends from the front section of the ceiling to the front panel reinforcement member.

Cab and work vehicle

A box section of a cab is detachable in a motor grader. The motor grader is provided with a bracket and a first controller. The bracket is attachable to a floor section. The first controller is attachable in a selective manner to the box section and the bracket and controls equipment required for travel.

A duct connected to an air-conditioning apparatus includes a portion positioned closer to a side window than a console when viewed from above. A tray is arranged on the console on a side close to the side window, and covers an area above the duct. A lower end of the side window is positioned lower than an upper end of the console positioned on the side close to the side window in terms of height from a floor surface. The tray is positioned on or below an imaginary straight line A-A connecting the upper end to the lower end of the side window, and is not positioned above imaginary straight line A-A. Accordingly, high visibility can be ensured in an obliquely downward direction lateral to an operator while a satisfactory aesthetic appearance of indoor space in a cab is maintained.

A cab body has a panel section. The panel section includes a concave section that is recessed upward. A floor frame includes a convex section and supports the cab body. The convex section has a shape that protrudes facing upward and is arranged to protrude from the concave section. A seal member seals a gap between the concave section and the convex section. The seal member has a first contact surface, a second contact surface, and an inclined surface. The first contact surface contacts the convex section. The second contact surface contacts the panel section. The inclined surface is inclined with regard to the first contact surface and the second contact surface. A bracket has an attachment section and a pressing surface. The attachment section is attached to the panel section. The pressing surface presses the inclined surface.
