[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the work vehicle disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described below.

[0010] First Embodiment <Outline of the work vehicle (tractor)> First, an overview of a work vehicle 1 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic side view showing a work vehicle 1 according to the first embodiment.

[0011] In the following description, an agricultural tractor (hereinafter simply referred to as "tractor") will be used as an example of the work vehicle 1. In addition, in the following description, the work vehicle (tractor) 1 may be referred to as the "machine body."

[0012] Tractor 1, which is a work vehicle, can travel on roads and fields using the power of a prime mover such as an engine E, which is a drive source. Tractor 1 is detachably equipped with a number of different types of work implements (not shown), each of which performs ground work, and performs predetermined work in the field.

[0013] As shown in Figure 1, tractor 1 has engine E mounted on hood 2 at the front of the vehicle body. Rotational power from engine E is transmitted to transmission 3, which is a speed change device, and after being reduced in transmission 3, is transmitted to front wheels 4 and rear wheels 5, which are the traveling wheels.

[0014] For example, a work implement such as a rotary work implement can be attached to the rear of the body of the tractor 1. The work implement is driven by a PTO (Power Take-Off) shaft 100 that protrudes rearward from a casing (transmission case) of the transmission 3.

[0015] A cabin 6 in which the driver sits is located behind the hood 2. A cockpit 7 in which the driver sits is located inside the cabin 6. An operating unit 8 is located around the cockpit 7. The operating unit 8 is equipped with operating devices such as a steering wheel 9. The operating unit 8 includes the steering wheel 9, operating pedals such as an accelerator pedal 10, a clutch pedal 11, and a brake pedal 12, operating levers such as a forward / reverse lever 13, a main shift lever 14, and an auxiliary shift lever (not shown), and operating devices such as various switches.

[0016] The steering wheel 9 is disposed in front of the driver's seat 7. The steering wheel 9 is operated (steering operation) by the driver when steering the front wheels 4, which are the steered wheels. In front of the steering wheel 9, a meter panel 15 (see FIG. 2) and the like are disposed.

[0017] The tractor 1 is equipped with a control device (not shown). The control device includes an engine ECU (Electronic Control Unit), a travel system ECU, and a work implement lifting system ECU. The engine ECU controls the rotation speed of the engine E (see FIG. 1). The travel system ECU controls the rotation of drive wheels such as the rear wheels 5 (see FIG. 1), thereby controlling the travel speed of the tractor 1. The work implement lifting system ECU controls the lifting device (not shown) of the tractor 1, thereby controlling the lifting and lowering of the work implement.

[0018] The control device is capable of controlling each part through electronic control, and is equipped with a processing unit having a CPU (Central Processing Unit), etc., as well as a memory unit consisting of a hard disk, ROM (Read Only Memory), RAM (Random Access Memory), etc., in which various programs and data are stored.

[0019] The tractor 1 may also be equipped with a positioning device (not shown). The positioning device is provided, for example, on top of the cabin 6, and measures the position of the tractor 1 (its own position) at a predetermined interval to obtain information (latitude and longitude) on the own position of the tractor 1. The positioning device is, for example, a GNSS (Global Navigation Satellite System) device, and receives radio waves from navigation satellites orbiting in the sky to determine its position and keep time.

[0020] In such a tractor 1, when the operator switches from manual driving mode to automatic driving mode by operating a selector switch, the control device creates a work route including the work start point within the field F (see Figure 2), and the tractor can perform work (autonomous work) while automatically driving along the generated work route.

[0021] <Internal configuration of the cabin> Next, the internal configuration of the cabin 6 will be described with reference to Fig. 2. Fig. 2 is an explanatory diagram of the work vehicle (tractor) 1 according to the first embodiment, viewed from the driver's seat 7 towards the front of the vehicle body.

[0022] 2, the cabin 6 includes left and right pillars 6a extending in the vertical direction on the left and right sides of the front of the cabin 6. The pillars 6a are exposed inside the cabin 6. A windshield 6b is provided between the left and right pillars 6a.

[0023] In addition, the tractor 1 may be equipped with a monitor 20 that can display meter displays and driving displays, etc. displayed on the display unit of the meter panel and work setting displays, etc. displayed on a display unit located on either the left or right side of the operator's seat 7 on a single screen, to prevent the operator from having to alternate between these displays.

[0024] Inside the cabin 6, in addition to the operator's seat 7 and the operation unit 8, a monitor 20 is also arranged around the operator's seat 7. The monitor 20 displays various information about the tractor 1 (meter display, travel display, work setting display, etc.) on a display screen 20a of the monitor 20. The monitor 20 displays, for example, control of the engine E, control of the aftertreatment device of the engine E, setting display of travel control and work control, and abnormality display of the vehicle. The monitor 20 also constantly displays information such as the remaining amount of fuel, the remaining amount of urea, the gear position, and the vehicle speed on a part of the display screen 20a.

[0025] The monitor 20 includes a first monitor 21. The first monitor 21 displays various types of information about the tractor 1 on a display screen 21a of the first monitor 21.

[0026] <Monitor (1st monitor) placement> Next, the arrangement of the monitor 20 (first monitor 21) will be described with reference to Figures 2 and 3. Figure 3 is an explanatory diagram of the arrangement of the first monitor 21.

[0027] 2 and 3, the first monitor 21 has a rectangular outer shape. The first monitor 21 is a so-called tablet-type monitor. The display screen 21a of the first monitor 21 is, for example, a liquid crystal screen. The display screen 21a of the first monitor 21 is a so-called touch panel screen that can accept operations (touch operations) by the operator on this display screen 21a.

[0028] The first monitor 21 is attached to one of the left and right pillars 6a. In the example shown in FIG. 2 etc., the first monitor 21 is attached to the right pillar 6a. By attaching the first monitor 21 to the right pillar 6a, the first monitor 21 is positioned to the right of the pilot seated in the cockpit 7 when looking forward at the aircraft. This makes it easier for the pilot to operate the monitor with his or her right hand. The first monitor 21 may also be attached to the left pillar 6a.

[0029] The first monitor 21 is disposed such that the long side of the long and short sides of the rectangular first monitor 21 runs along the vertical direction. The first monitor 21 is attached to the pillar 6a so that at least a portion of the first monitor 21 overlaps with the pillar 6a. A portion of the first monitor 21 in the width direction (the horizontal direction) overlaps with the pillar 6a. Note that if the width dimension of the pillar 6a is larger than that of the first monitor 21, the entire width of the first monitor 21 may overlap with the pillar 6a.

[0030] When the operator drives the tractor 1, he or she operates operating tools such as the steering wheel 9 while checking the front, rear, left and right conditions of the vehicle. For this reason, the first monitor 21 needs to be positioned so as not to obstruct the operator's field of vision (for example, area A in front of the vehicle) and so that the information displayed on the display screen 21a of the first monitor 21 is easy to see.

[0031] According to the configuration of the first embodiment, the first monitor 21 is disposed on the pillars 6a on the left and right sides of the front of the cabin 6. This allows the pilot to check information such as the driving status displayed on the display screen 21a of the first monitor 21 without significantly averting his or her eyes from the viewpoint while the aircraft is traveling, thereby reducing the impact on pilotage caused by the first monitor 21 being disposed in front of the cockpit 7. Furthermore, because the longitudinal direction of the first monitor 21 is vertical and at least a portion of the first monitor 21 overlaps with the pillar 6a, the first monitor 21 does not extend beyond the pillar 6a to a great extent, and the pilot's field of view (area A) is less likely to be obstructed. For example, compared to when the longitudinal direction of the first monitor 21 is horizontal, the pilot's field of view (area A) is less obstructed. Thus, according to the configuration of the first embodiment, it is possible to suppress the deterioration of maneuverability and safety caused by the first monitor 21 being disposed in front of the cockpit 7.

[0032] As shown in FIG. 2, the first monitor 21 is disposed so that the lower end of the first monitor 21 is located above the steering handle 9.

[0033] Here, when the operator drives the tractor 1, he or she looks at something far in the direction of travel of the vehicle (in front of the vehicle), so if the monitor 20 (first monitor 21) is placed in a low position, such as on either the left or right side of the steering handle 9, the operator's viewpoint will move significantly up and down when checking the monitor 20 (first monitor 21) while the vehicle is driving.

[0034] According to the configuration of the first embodiment, the lower end of the first monitor 21 is disposed so as to be located above the steering handle 9, that is, the first monitor 21 is disposed at a position at approximately the same height as the pilot's eye level, so that even when the pilot checks the display screen 21a of the first monitor 21 while the aircraft is traveling, the pilot's viewpoint does not move significantly in the vertical direction. This reduces the impact on piloting caused by the first monitor 21 being disposed in front of the cockpit 7.

[0035] 3, the first monitor 21 is disposed in an inclined position such that the closer to either the left or right end of the first monitor 21 is located the farther rearward of the aircraft. In the example shown in FIG. 3, the first monitor 21 is disposed in an inclined position such that the closer to the right end of the first monitor 21 is located the further rearward of the aircraft. In other words, the first monitor 21 is disposed with a predetermined angle α inclined toward the rear of the aircraft. With this configuration, the display screen 21a of the first monitor 21 faces the cockpit 7, making the display screen 21a easier to see from the cockpit 7.

[0036] <Example of display screen on monitor (1st monitor)> Next, a display example of the display screen 20a (21a) of the monitor 20 (first monitor 21) will be described with reference to Figures 4 to 6. Figures 4 to 6 are diagrams showing a display example of the display screen 21a of the first monitor 21.

[0037] 4, the first monitor 21 displays a meter display in an upper area 21aa, which is the upper part of the display screen 21a. The first monitor 21 also displays a driving display and an operation setting display in a lower area 21ab, which is below the upper part of the display screen 21a. For example, the lower area 21ab is approximately two-thirds of the entire area of ​​the display screen 21a.

[0038] It is also preferable that the first monitor 21 always displays a meter display in the upper area 21aa. The first monitor 21 can switch the meter display in the upper area 21aa, for example, from a numerical display as shown in Fig. 4 to a pointer-type display as shown in Fig. 5, depending on the running state of the tractor 1.

[0039] Furthermore, the display screen 21a of the first monitor 21 can be switched to a screen that allows the pilot to operate the jog dial. The first monitor 21 can switch the work setting display in the lower area 21ab to a display that allows jog dial operation, for example, as shown in Fig. 6. In this way, by setting operations that require a long operation time to be touch operations and operations that can be completed in a short time, such as operations required while the vehicle is traveling, to jog dial operations, operability can be improved.

[0040] <Monitor (1st monitor) mounting structure> Next, the mounting structure of the monitor 20 (first monitor 21) will be described with reference to Figures 7 to 11. Figures 7 and 8 are explanatory diagrams of a first mounting structure of the first monitor 21. Figure 8 is an explanatory diagram of a second mounting structure of the first monitor 21. Figures 10 and 11 are explanatory diagrams of a third mounting structure of the first monitor 21.

[0041] For example, as shown in Fig. 7, the first monitor 21 is attached to a pillar 6a of the cabin 6 (see Fig. 2) by being supported by an arm 23 (23a). Here, because there is a distance from the pillar 6a of the cabin 6 to the cockpit 7, when operating the first monitor 21 attached to the pillar 6a, the pilot has difficulty reaching the first monitor 21 from the cockpit 7, and has to operate the first monitor 21 in a leaning-forward position.

[0042] Therefore, the arm 23 (23a) supports the first monitor 21 so that it can move from the pillar 6a toward the cockpit 7. One end of the arm 23 (23a) is attached to the pillar 6a, and the first monitor 21 is attached to the other end. In the example shown in Figures 7 and 8, the arm 23a is configured with an extendable and retractable lazy tongue mechanism that combines multiple four-bar links.

[0043] With this configuration, the pilot can pull the first monitor 21 attached to the pillar 6a toward the pilot's seat 7, and can operate the first monitor 21 without having to lean forward. This improves the operability of the first monitor 21.

[0044] Further, a hand catcher 211 may be provided below the first monitor 21, on which the operator can place their hand when operating the first monitor 21.

[0045] 9, one end of the arm 23 (23b) is rotatably attached to the ceiling 6c of the cabin 6 via a rotating part 23ba, and the first monitor 21 is rotatably attached to the other end via a rotating part 23bb. Therefore, the first monitor 21 can move in a pendulum manner via the arm 23b.

[0046] With this configuration, the pilot W can pull the first monitor 21 attached to the pillar 6a toward the pilot's seat 7, and the pilot W can operate the first monitor 21 without having to lean forward. This improves the operability of the first monitor 21.

[0047] In the example shown in FIG. 9, for example, when the first monitor 21 is not in use, the first monitor 21 can be placed on the ceiling 6c of the cabin 6, thereby putting the first monitor 21 into a stored state.

[0048] In the example shown in FIGS. 10 and 11, one end of the arm 23 (23c) is rotatably attached to a pillar 6a of the cabin 6 (see FIG. 2), and the first monitor 21 is attached to the other end. The arm 23c is configured with a link mechanism that can be folded in two. The arm 23c may be provided with a damper mechanism 24. When the first monitor 21 moves via the arm 23c, the damper mechanism 24 holds the first monitor 21 in the position to which it has moved. The damper mechanism 24 also reduces the load on the operator when moving the arm 23c. A harness 25 is connected to the first monitor 21.

[0049] With this configuration, the pilot can pull the first monitor 21 attached to the pillar 6a toward the pilot's seat 7, and can operate the first monitor 21 without having to lean forward. This improves the operability of the first monitor 21.

[0050] In addition, at the bottom of the first monitor 21, there is a display for the operator to hold by hand H when moving the first monitor 21. W A hand catcher 212 may be provided that can be grasped with the

[0051] 9, the first monitor 21 is disposed in an inclined position such that the position becomes further rearward of the aircraft body as it approaches the upper end of the first monitor 21. In the example shown in Fig. 9, the first monitor 21 is disposed in an inclined position such that the position becomes further rearward of the aircraft body as it approaches the upper end of the first monitor 21. In other words, the first monitor 21 is disposed with a predetermined angle β tilted toward the rear of the aircraft body.

[0052] With this configuration, the display screen 21a of the first monitor 21 does not reflect light (external light) outside the aircraft, and the scenery outside the aircraft is not reflected on the display screen 21a, making the display screen 21a easier to see from the cockpit 7.

[0053] Second Embodiment Next, a work vehicle (tractor) 1 according to a second embodiment will be described with reference to Figures 12 to 17. The second embodiment described below differs from the first embodiment described above in the configuration of the monitor 20, but other parts have the same or equivalent configurations. For this reason, the same reference numerals will be used below to refer to parts that are the same as or equivalent to those in the first embodiment, and descriptions of parts to which the same reference numerals are used may be omitted.

[0054] <Internal configuration of the cabin> The internal configuration of the cabin 6 will be described with reference to Fig. 12. Fig. 12 is an explanatory diagram of a work vehicle (tractor) 1 according to the second embodiment, viewed from the driver's seat 7 towards the front of the vehicle body.

[0055] As shown in FIG. 12, monitors 20 are arranged inside the cabin 6 around the driver's seat 7. The monitors 20 display various types of information about the tractor 1 (meter display, travel display, work setting display, etc.) on a display screen 20a of the monitors 20. The monitors 20 include a first monitor 21 and a second monitor 22. The first monitor 21 displays various types of information about the tractor 1 on a display screen 21a of the first monitor 21.

[0056] The second monitor 22 displays, on the display screen 22a of the second monitor 22, for example, that the tractor 1 (see FIG. 1) is in the automatic driving mode and the deviation of the driving direction of the tractor 1 when in the automatic driving mode. The second monitor 22 functions as a so-called guidance monitor that provides guidance for the automatic driving of the tractor 1.

[0057] <Monitor (1st and 2nd monitor) placement> Next, the arrangement of the monitors 20 (first monitor 21 and second monitor 22) will be described with reference to Figures 12 and 13. Figure 13 is an explanatory diagram of the arrangement of the first monitor 21 and second monitor 22.

[0058] 12 and 13, the first monitor 21 has a rectangular outer shape. The first monitor 21 is a so-called tablet-type monitor. The display screen 21a of the first monitor 21 is, for example, a liquid crystal screen. The display screen 21a of the first monitor 21 is a so-called touch panel screen that can accept an operation (touch operation) by the operator on this display screen 21a. The display screen 21a of the first monitor 21 may be capable of accepting a jog dial operation in addition to a touch operation.

[0059] The first monitor 21 is attached to one of the left and right pillars 6a. In the example shown in FIG. 12 etc., the first monitor 21 is attached to the right pillar 6a. By attaching the first monitor 21 to the right pillar 6a, the first monitor 21 is positioned to the right of the pilot seated in the cockpit 7 when looking forward at the aircraft. This makes it easier for the pilot to operate the monitor with his or her right hand. The first monitor 21 may also be attached to the left pillar 6a.

[0060] The first monitor 21 is disposed such that the long side of the long and short sides of the rectangular first monitor 21 runs along the vertical direction. The first monitor 21 is attached to the pillar 6a so that at least a portion of the first monitor 21 overlaps with the pillar 6a. In this case, a portion of the first monitor 21 in the width direction (the horizontal direction) overlaps with the pillar 6a. Note that if the width dimension of the pillar 6a is larger than that of the first monitor 21, the entire width of the first monitor 21 may overlap with the pillar 6a.

[0061] The second monitor 22 has a rectangular outer shape. The second monitor 22 is a so-called tablet-type monitor. The display screen 22a of the second monitor 22 is, for example, a liquid crystal screen. The display screen 22a of the second monitor 22 is a so-called touch panel screen that can accept an operation (touch operation) by the operator on this display screen 22a. The display screen 22a of the second monitor 22 may be capable of accepting a jog dial operation in addition to a touch operation.

[0062] The second monitor 22 is attached to one of the left and right pillars 6a. In the example shown in FIG. 12 etc., the second monitor 22 is attached to the right pillar 6a. The second monitor 22 is disposed above or below the first monitor 21 and is disposed close to the first monitor 21. In the example shown in FIG. 12 etc., the second monitor 22 is disposed below the first monitor 21. Furthermore, by attaching the second monitor 22 to the right pillar 6a, the second monitor 22 is disposed to the right of the pilot seated in the cockpit 7 when looking forward at the aircraft. This makes it easier for the pilot to operate the monitor with his or her right hand. The second monitor 22 may also be attached to the left pillar 6a.

[0063] The second monitor 22 is disposed such that the shorter side of the long and short sides of the rectangular second monitor 22 runs along the vertical direction. The second monitor 22 may also be disposed such that the longer side of the second monitor runs along the vertical direction. The second monitor 22 is attached to the pillar 6a so that at least a portion of the second monitor 22 overlaps with the pillar 6a. A portion of the second monitor 22 in the width direction, which is the horizontal direction, overlaps with the pillar 6a. If the width dimension of the pillar 6a is larger than that of the second monitor 22, the entire width of the second monitor 22 may overlap with the pillar 6a.

[0064] When the operator drives the tractor 1, he or she operates operating tools such as the steering wheel 9 while checking the conditions in the front, back, left and right of the vehicle. For this reason, the first monitor 21 and the second monitor 22 need to be positioned so as not to obstruct the operator's field of vision (for example, area A in front of the vehicle shown in FIG. 12), and also need to be positioned so that the information displayed on the display screen 21a of the first monitor 21 and the display screen 22a of the second monitor 22 is easy to see.

[0065] According to the configuration of the second embodiment, two monitors 20, a first monitor 21 and a second monitor 22, are disposed on pillars 6a on the left and right sides of the front of the cabin 6. This allows the pilot to check information such as the driving status displayed on the display screens 21a, 22a of the first monitor 21 and the second monitor 22, respectively, without significantly averting his or her line of sight from the viewpoint while the aircraft is traveling, thereby reducing the impact on piloting caused by the monitors 20 (the first monitor 21 and the second monitor 22) being disposed in front of the cockpit 7. Furthermore, because the longitudinal direction of the first monitor 21 is the up-down direction and a portion of the first monitor 21 overlaps with the pillar 6a, the first monitor 21 does not extend beyond the pillar 6a to a great extent, and the pilot's field of view (area A) is less likely to be obstructed. For example, the pilot's field of view (area A) is less obstructed than when the longitudinal direction of the first monitor 21 is the left-right direction. Furthermore, even when the monitor 20 includes the second monitor 22, the pilot can check the information on the driving state displayed on the second monitor 22 without significantly averting his or her eyes from the viewpoint while the aircraft is traveling, thereby reducing the impact on pilotage caused by the second monitor 22 being located in front of the cockpit 7. Furthermore, because a portion of the second monitor 22 overlaps with the pillar 6a, the second monitor 22 does not extend beyond the pillar 6a to a great extent, and is less likely to obstruct the pilot's field of view (area A). Thus, the configuration of the second embodiment makes it possible to suppress degradation of pilotability and safety caused by the monitor 20 (first monitor 21 and second monitor 22) being located in front of the cockpit 7.

[0066] 12, the second monitor 22 is disposed so that the lower end of the second monitor 22 is located above the steering handle 9. When the second monitor 22 is disposed above the first monitor 21, the lower end of the first monitor 21 is disposed so that the lower end of the first monitor 21 is located above the steering handle 9.

[0067] Here, when the operator drives the tractor 1, he or she looks at something far in the direction of travel of the vehicle (in front of the vehicle), so if the monitor 20 (first monitor 21 and second monitor 22) is positioned at a low position, such as on either the left or right side of the steering handle 9, the operator's viewpoint will move significantly in the vertical direction when checking the monitor 20 (first monitor 21 and second monitor 22) while the vehicle is driving.

[0068] According to the configuration of the second embodiment, the lower of the two monitors 20, the second monitor 22 (or the first monitor 21), is disposed so that its lower end is located above the steering handle 9. In other words, the first monitor 21 and the second monitor 22 are disposed at positions that are approximately the same height as the pilot's eye level. Therefore, even when the pilot checks the display screen 21a of the first monitor 21 and the display screen 22a of the second monitor while the aircraft is traveling, the pilot's viewpoint does not move significantly in the vertical direction. This reduces the impact on piloting caused by the first monitor 21 and the second monitor 22 being disposed in front of the cockpit 7.

[0069] 13, the first monitor 21 is disposed in an inclined position such that the closer to either the left or right end of the first monitor 21 is located the farther rearward of the aircraft. In the example shown in FIG. 13, the first monitor 21 is disposed in an inclined position such that the closer to the right end of the first monitor 21 is located the further rearward of the aircraft. In other words, the first monitor 21 is disposed with a predetermined angle α1 inclined toward the rear of the aircraft. With this configuration, the display screen 21a of the first monitor 21 faces the cockpit 7, making the display screen 21a easier to see from the cockpit 7.

[0070] 13, the second monitor 22 is disposed in an inclined position such that the closer to either the left or right end of the second monitor 22 is located the farther rearward of the aircraft. In the example shown in FIG. 13, the second monitor 22 is disposed in an inclined position such that the closer to the right end of the second monitor 22 is located the further rearward of the aircraft. In other words, the second monitor 22 is disposed with a predetermined angle α2 inclined toward the rear of the aircraft. With this configuration, the display screen 22a of the second monitor 22 faces toward the cockpit 7, making the display screen 22a easier to see from the cockpit 7.

[0071] <Example of monitor (second monitor) display screen> Next, a display example of the display screen 20a (22a) of the monitor 20 (second monitor 22) will be described with reference to Fig. 14. Fig. 14 is a diagram showing a display example of the display screen 22a of the second monitor 22.

[0072] 14, the second monitor 22 displays on the display screen 22a of the second monitor 22, for example, that the tractor 1 (see FIG. 1) is in automatic driving mode when the tractor 1 is driving automatically. Also, the second monitor 22 displays on the display screen 22a of the second monitor 22, for example, the deviation in the driving direction of the tractor 1 when the tractor 1 is driving automatically.

[0073] <Monitor (1st and 2nd monitor) mounting structure> Next, the mounting structure of the monitor 20 (first monitor 21 and second monitor 22) will be described with reference to Figures 15 and 17. Figures 15 and 16 are explanatory diagrams of the mounting structure of the first monitor 21 and second monitor 22. Note that Figure 15 shows a schematic side view of the first monitor 21 and the second monitor 22, and Figure 16 shows a schematic perspective view from above of the first monitor 21 and the second monitor 22. Figure 17 is an explanatory diagram of the movable range of the second monitor 22.

[0074] 15 and 16, the first monitor 21 is supported by a base portion 231 that constitutes the arm 23 (23d). The first monitor 21 is attached to a pillar 6a of the cabin 6 (see FIG. 2) by the base portion 231 fixed to the pillar 6a.

[0075] The second monitor 22 is supported by an arm portion 232 that constitutes the arm 23d. One end of the arm portion 232 is attached to the base portion 231. The arm portion 232 is attached to the base portion 231 via a first rotation portion 2311 so as to be rotatable in the left-right direction. The second monitor 22 is attached to the other end of the arm portion 232.

[0076] The arm section 232 supports the second monitor 22 via a second rotation section 2321. The second rotation section 2321 includes a vertical rotation section 2321a and a horizontal rotation section 2321b. The vertical rotation section 2321a is rotatable in the vertical direction. The horizontal rotation section 2321b is rotatable in the horizontal direction. By means of this second rotation section 2321, the arm section 232 supports the second monitor 22 so that it can rotate up and down and left and right.

[0077] Here, since there is a distance between the pillar 6a of the cabin 6 and the cockpit 7, when operating the second monitor 22, it is difficult for the pilot to reach the second monitor 22 from the cockpit 7, and the pilot has to operate the second monitor 22 in a leaning-forward position.

[0078] The arm section 232 is configured with a link mechanism that can be folded in two. Note that the arm section 232 may be provided with a damper mechanism that holds the second monitor 22 in the position to which it has moved when the second monitor 22 moves via the arm section 232.

[0079] According to the configuration of the second embodiment, the pilot can pull the second monitor 22 toward the pilot's seat 7, and the pilot can operate the second monitor 22 without having to lean forward. This improves the operability of the second monitor 22.

[0080] Furthermore, the first monitor 21 may be disposed in an inclined position such that the upper end of the first monitor 21 is positioned further rearward of the aircraft. In this case, the first monitor 21 is disposed tilted at a predetermined angle rearward of the aircraft. With this configuration, the display screen 21a of the first monitor 21 does not reflect light outside the aircraft (external light) and the scenery outside the aircraft is not reflected on the display screen 21a, making it easier to view the display screen 21a from the cockpit 7.

[0081] The second monitor 22 may also be disposed in an inclined position such that the upper end of the second monitor 22 is positioned further rearward of the aircraft. In this case, the second monitor 22 is disposed tilted at a predetermined angle rearward of the aircraft. With this configuration, the display screen 22a of the second monitor 22 does not reflect light outside the aircraft (external light) and the scenery outside the aircraft is not reflected on the display screen 22a, making the display screen 22a easier to see from the cockpit 7.

[0082] 17, the arm portion 232 is rotatable in the left-right direction within a predetermined range R. This allows the operator to place the second monitor 22 at a position where the operator can easily check the display screen 22a, and at an angle where the operator can easily check the display screen 22a.

[0083] For example, if a rearview mirror is disposed on the upper portion of one of the left and right pillars 6a (for example, the right pillar 6a), the first monitor and the second monitor 22 may be disposed below the rearview mirror. In this case, the first monitor and the second monitor 22 may be disposed on either side of the rearview mirror.

[0084] The above-described embodiment realizes the following work vehicle 1.

[0085] (1) A work vehicle 1 comprising: a cabin 6 having pillars 6a extending in the vertical direction on the left and right sides of the front; a driver's seat 7 located inside the cabin 6 and seated by a driver; an operating unit 8 located around the driver's seat 7 inside the cabin 6 and operated by the driver; and a monitor 20 located around the driver's seat 7 inside the cabin 6 and displaying various information on a display screen 20a, the monitor 20 having a rectangular outer shape with its long side aligned in the vertical direction and attached to the pillar 6a so that at least a portion of the monitor 20 overlaps with the pillar 6a.

[0086] According to this work vehicle 1, the monitors 20 are disposed on the pillars 6a on the left and right sides of the front of the cabin 6. This allows the operator to check information such as the driving status displayed on the display screen 20a of the monitor 20 without significantly averting his or her eyes from the viewpoint while the vehicle is traveling, thereby reducing the impact on operation caused by the monitor 20 being disposed in front of the cockpit 7. Furthermore, because the longitudinal direction of the monitor 20 is vertical and at least a portion of the monitor 20 overlaps with the pillar 6a, the monitor 20 does not extend beyond the pillar 6a to a great extent, making it less likely to obstruct the operator's field of view. For example, the monitor 20 does not obstruct the operator's field of view as much as when the longitudinal direction of the monitor 20 is horizontal. In this way, according to this work vehicle 1, it is possible to prevent a decrease in maneuverability and safety caused by the monitor 20 being disposed in front of the cockpit 7.

[0087] (2) A work vehicle 1 comprising: a cabin 6 having pillars 6a extending in the vertical direction on the left and right sides of the front; a driver's seat 7 located inside the cabin 6 and seated by a driver; an operating unit 8 located around the driver's seat 7 inside the cabin 6 and operated by the driver; and a monitor 20 located around the driver's seat 7 inside the cabin 6 and displaying various information on a display screen 20a, the monitor 20 including a first monitor 21 and a second monitor 22, the first monitor 21 having a rectangular outer shape with its long side aligned in the vertical direction and attached to the pillar 6a so that at least a portion of the first monitor 21 overlaps with the pillar 6a, and the second monitor 22 having a rectangular outer shape and located above or below the first monitor 21 and attached to the pillar 6a so that at least a portion of the second monitor 22 overlaps with the pillar 6a.

[0088] According to this work vehicle 1, two monitors 20, a first monitor 21 and a second monitor 22, are disposed on pillars 6a on the left and right sides of the front of the cabin 6, so that the operator can check information such as the driving status displayed on the display screens 21a, 22a of the first monitor 21 and the second monitor 22, respectively, without significantly averting his or her line of sight from the viewpoint while the vehicle is traveling, thereby reducing the impact on operation caused by the monitors 20 (the first monitor 21 and the second monitor 22) being disposed in front of the cockpit 7. Furthermore, because the longitudinal direction of the first monitor 21 is the up-down direction and a portion of the first monitor 21 overlaps with the pillar 6a, the first monitor 21 does not protrude beyond the pillar 6a to a great extent, and the operator's field of view is less obstructed. For example, the operator's field of view is less obstructed than when the longitudinal direction of the first monitor 21 is the left-right direction. Furthermore, even when the monitor 20 includes the second monitor 22, the operator can check the information on the driving state displayed on the second monitor 22 without having to significantly avert his or her eyes from the viewpoint while the vehicle is driving, thereby reducing the impact on driving caused by the second monitor 22 being located in front of the cockpit 7. Furthermore, because a portion of the second monitor 22 overlaps with the pillar 6a, the second monitor 22 does not extend beyond the pillar 6a to a great extent, and is less likely to obstruct the operator's field of vision. In this way, with this work vehicle 1, it is possible to prevent a decrease in maneuverability and safety caused by the monitor 20 (first monitor 21 and second monitor 22) being located in front of the cockpit 7.

[0089] (3) In the work vehicle 1 described above in (1) or (2), the operating unit 8 is located in front of the driver's seat 7 inside the cabin 6 and includes a steering handle 9 that is operated by the driver, and the monitor 20 is positioned so that the lower end of the monitor 20 is located above the steering handle 9.

[0090] According to this work vehicle 1, in addition to the effects of (1) or (2) above, the lower end of the monitor 20 is positioned above the steering handle 9, that is, the monitor 20 is positioned at a height approximately equal to the eye level of the operator, so even when the operator checks the display screen 20a of the monitor 20 while the vehicle is traveling, the operator's viewpoint does not move significantly in the vertical direction. This reduces the impact on operation caused by the monitor 20 being positioned in front of the operator's seat.

[0091] (4) In the work vehicle 1 described above in (3), the monitor 20 is disposed in an inclined position such that the upper end of the monitor 20 is positioned further rearward from the vehicle body.

[0092] According to such a work vehicle 1, in addition to the effect (3) above, the display screen 20a does not reflect light (external light) outside the vehicle and the scenery outside the vehicle does not appear on the display screen 20a, making the display screen 20a easier to see from the cockpit 7.

[0093] (5) In the work vehicle 1 described above in (3), the monitor 20 is positioned in an inclined position such that the end of the monitor 20 farthest from the cockpit 7 is positioned further rearward from the vehicle body.

[0094] According to such a work vehicle 1, in addition to the effect (3) above, the display screen 20a of the monitor 20 faces the driver's seat 7, making it easier to see the display screen 20a from the driver's seat 7.

[0095] (6) In the work vehicle 1 described above in (1) or (2), the monitor 20 can accept touch operations by the operator on the display screen 20a, and is attached to the pillar 6a by being supported by the arm 23, and the arm 23 supports the monitor 20 so that it can move from the pillar 6a toward the operator's seat 7.

[0096] In addition to the effects (1) and (2) above, this work vehicle 1 allows the operator to pull the monitor 20 attached to the pillar 6a toward the operator's seat 7, enabling the operator to operate the monitor 20 without having to lean forward. This improves the operability of the monitor 20.
