Abstract: A wheel loader as a work vehicle includes a ladder, an operator's compartment, an actuator, an operation unit, and a controller. The operator's compartment has an openable and closable door disposed above the ladder. The actuator is disposed at the operator's compartment so as to actuate the door to make an opening motion. The operation unit receives an operation from an operator. The controller controls the drive of the actuator, based on an operation signal received from the operation unit, so that the door makes an opening motion while the operation unit is receiving an operation from the operator.

Abstract: A wheel loader comprises a console box and a support component. The console box is disposed on the side of an operator's seat and is able to rotate in the forward and backward direction. The support component has a rotary shaft disposed in the left and right direction under the console box, and rotatably supports the console box around the rotary shaft between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position and is disposed at an angle. The location of the center of gravity of the console box is disposed more to the front than the rotary shaft at the operation position, and more to the rear than the rotary shaft at the retracted position.

Abstract: A handle is supported by a hollow tube so as to be movable in the direction in which the handle is pushed toward a hollow space. A hole leading to the hollow space of the hollow tube has a first hole portion located at one end of a base portion extending in a longitudinal direction L of the hollow tube and a second hole portion extending from the first hole portion to a portion corresponding to the other end of the base portion in the longitudinal direction L. A dimension W2b of a grip portion of the handle in a width direction W is greater than a dimension W2a of the base portion of the handle in the width direction W and greater than a dimension W1a of the second hole portion in the width direction W.

Abstract: A wheel loader includes a console box, a link rod, and a shutoff valve. The console box is disposed on the side of an operator's seat, is able to rotate in the forward and backward direction between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position, and has a slot. The link rod is connected at one end to the slot and transmits the rotation of the console box. The link rod is able to rotate a shaft to switch between an open position in which an actuator drive-use hydraulic circuit can be actuated, and a closed position in which the actuator drive-use hydraulic circuit cannot be actuated. A second end of the link rod is linked to the shaft.

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.

Abstract: The wheel loader includes a console box and a bellows. The console box is disposed on the side of an operator's seat, and is rotatable in the forward and backward direction between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position. The bellows has a lower end and an upper end. The lower end is fixed on the floor side of the operator's seat. The upper end is rotatably linked to the console box in the forward and backward direction around a rotary shaft running in the left and right direction.

Abstract: A fixture is attached to a hollow tube and has a pair of shafts protruding in a width direction. A handle has a base portion and a grip portion located at an end on the outside of the base portion. The base portion has a pair of side portions sandwiching both side surfaces of the fixture. The pair of side portions each have a hole receiving corresponding one of the pair of shafts. A restriction portion of a displacement preventing plate restricts a movement of the side portions in the width direction in a portion of each of the side portions located between an end on the grip portion side of the fixture and an end on the hollow space side of the base portion.

Abstract: A cab for a work machine includes a cab body that is formed with a doorway, a door that is rotatably supported on the cab body so as to open and close the doorway, an actuator that generates a driving force to open and close the door, a rod that is attached to the door and rotatable relative to the door, and a sensor that is attached to the door separately from the rod. The sensor detects the motion of the rod relative to the door by detecting the motion of the rod relative to the sensor.
