Then, the direction perpendicular to the front-rear direction and the left-right direction of the tractor is defined as the up-down direction. At this time, the direction of gravity is defined as down, and the opposite side is defined as up. In the drawings, the front direction is indicated by F, the rear direction is indicated by B, the left direction is indicated by L, the right direction is indicated by R, the up direction is indicated by U, and the down direction is indicated by D as appropriate.

[0011] FIG. 1 is a side view showing a schematic configuration of a tractor 1 which is an example of the work vehicle of the present embodiment. The tractor 1 includes a vehicle body 2. The front portion of the vehicle body 2 is supported by a pair of left and right front wheels 3. The rear portion of the vehicle body 2 is supported by a pair of left and right rear wheels 4.

[0012] A bonnet 5 is disposed at the front portion of the vehicle body 2. An engine 6 as a drive source is disposed below the bonnet 5. That is, the tractor 1 includes the engine 6. The engine 6 is configured by, for example, a diesel engine, but is not limited thereto, and may be configured by, for example, a gasoline engine.

[0013] A driver's seat 7 on which an operator (driver) rides is provided behind the engine 6 in the vehicle body 2. The driver's seat 7 is provided with a steering wheel 8 for the driver to perform a steering operation and a driver's seat 9. The steering wheel 8 is rotatably supported by a steering column 10. That is, the tractor 1 includes the steering column 10 located at the driver's seat 7. The driver's seat 7 is also provided with an operation lever LV, a pedal P, etc. operated by the driver.

[0014] On the rear side of the vehicle body 2, a three-point link mechanism is provided. The three-point link mechanism includes a pair of left and right lower links 11 and an upper link (not shown). A work implement can be attached to the three-point link mechanism. As the work implement, for example, a tillage device, a plow, or a fertilizer applicator can be used, but it is not limited to these. Further, on the rear side of the vehicle body 2, a lifting device (not shown) having a hydraulic device such as a lifting cylinder is provided. By the lifting device lifting the three-point link mechanism, the work implement can be lifted and lowered.

[0015] In the vehicle body 2, a ROPS frame 12 is provided at the rear of the driver's seat 7 (driver's seat 9). The tractor 1 of the present embodiment is of a type in which the driver's seat 9 is not covered by a cabin. Therefore, the ROPS frame 12 is provided for the purpose of protecting the driver when the tractor 1 overturns.

[0016] In the vehicle body 2, the transmission case 13 is located behind the engine 6 and below the driver's seat 7. More specifically, the transmission case 13 is located below the steering column 10. A power transmission device (not shown) is arranged inside the transmission case 13. The rotational power of the engine 5 is transmitted to at least one of the front wheels 3 and the rear wheels 4 via the power transmission device in the transmission case 13.

[0017] In the vehicle body 2, a dashboard 14 is arranged between the bonnet 5 and the steering column 10. FIG. 2 is a perspective view when the dashboard 14 is viewed from the rear. The dashboard 14 has a first cover 141 and a second cover 142. The first cover 141 is made of a metal such as SUS.

[0018] The second cover 142 is located at the upper rear end of the first cover 141. The second cover 142 is made of resin. Examples of the resin include ABS (acrylonitrile-butadiene-styrene copolymer synthetic resin), PP (polypropylene resin), PE (polyethylene resin), PC (polycarbonate resin), and the like. A meter panel 142a indicating a speedometer, a fuel gauge, a water temperature gauge, etc. is installed at the rear end of the second cover 142.

[0019] Figure 3 is a perspective view showing the internal structure of the dashboard 14 shown in Figure 2. The tractor 1 includes a partition plate 20 which is a partitioning member. The partition plate 20 is a partition wall that partitions the inside of the bonnet 5 and the inside of the dashboard 14. The partition plate 20 is made of a metal plate with a thickness of about 10 mm, for example. The partition plate 20 is located between the bonnet 5 and the steering column 10, more specifically, between the engine 6 (see Figure 1) inside the bonnet 5 and the steering column 10. Thereby, the heat radiated rearward from the engine 6 is blocked by the partition plate 20.

[0020] The tractor 1 includes a fuel tank 30. The fuel tank 30 is a container for storing fuel. The fuel in the fuel tank 30 is supplied to the engine 6 through a fuel hose by a fuel pump (not shown). The fuel tank 30 is located between the partition plate 20 and the steering column 10.

[0021] Figure 4 is a perspective view of the fuel tank 30 when viewed from the rear. Figure 5 is a perspective view of the fuel tank 30 when viewed from the front. The fuel tank 30 has a front face portion 31 (see Figure 5), side face portions 32, an upper face portion 33, a bottom face portion 34, and a rear face portion 35 (see Figure 4).

[0022] The front face portion 31 is located opposite to the partition plate 20 (see Figure 3) within the dashboard 14. The front face portion 31 has a recess 31a. The recess 31a is composed of a groove extending in the vertical direction. The recess 31a is provided at two locations on the front face portion 31. The two recesses 31a are provided side by side with a space therebetween in the left-right direction.

[0023] The side faces 32 are respectively located on the left and right sides of the front face 31. The left and right side faces 32 are respectively connected to the left and right edge portions of the front face 31. Thereby, the left and right side faces 32 are connected to the front face 31. The upper face 33 is connected to the upper part of the front face 31 and the upper parts of the left and right side faces 32. Thereby, the upper face 33 is connected to the front face 31 and the left and right side faces 32.

[0024] The bottom face 34 is connected to the lower part of the front face 31 and the lower parts of the left and right side faces 32. Thereby, the bottom face 34 is connected to the front face 31 and the side faces 32. As shown in FIG. 5, the bottom face 34 has a shape in which the central part of the bottom face is recessed toward the upper face 33 side, but the bottom face 34 may be flat. The rear face 35 is connected to the upper face 33, the left and right side faces 32, and the bottom face 34.

[0025] FIG. 6 and FIG. 7 are respectively a perspective view and a side view showing a support structure of the fuel tank 30. The tractor 1 has a tank support portion 40. The tank support portion 40 supports the fuel tank 30 within the dashboard 14 (see FIG. 2). The tank support portion 40 has a side support portion 50 and a pressing portion 60.

[0026] A pair of side support portions 50 are provided on the left and right. Each side support portion 50 is connected to the partition plate 20 and supports the left and right side faces 32 of the fuel tank 50 respectively. Such a side support portion 50 has a plurality of contact portions 51 and a support stay 52.

[0027] Each contact portion 51 is composed of an elastic member (such as rubber) that contacts the side face 32 of the fuel tank 30. The plurality of contact portions 51 are supported by the support stay 52. Specifically, a part (protrusion) of each contact portion 51 is fitted into a hole formed in the support stay 52 from the fuel tank 30 side. Thereby, each contact portion 51 is supported by the support stay 52. In the present embodiment, two contact portions 51 are supported by one support stay 52. Note that the number of contact portions 51 supported by the support stay 52 is not limited to the above two, and may be three or more.

[0028] One end (front end) of the support stay 52 is connected to the partition plate 20. The other end (rear end) of the support stay 52 is connected to the pedal frame 70. That is, the tractor 1 includes the pedal frame 70. FIG. 8 is a perspective view of the pedal frame 70. In FIGS. 6 and 7 above, for the sake of convenience, only a part (the connecting part with the support stay 52) of the pedal frame 70 is shown. The pedal frame 70 is located between the fuel tank 30 and the steering column 10 (see FIG. 3). The pedal frame 70 is a frame that supports a plurality of pedals P and is fixed to the chassis (not shown) of the vehicle body 2 shown in FIG. 1.

[0029] As shown in FIG. 7, the support stay 52 has a first arm portion 52a and a second arm portion 52b. The first arm portion 52a extends rearward from the front end along the side surface portion 32 of the fuel tank 30, bends upward, and then further bends rearward and extends. The second arm portion 52b is fixed to the upper portion of the first arm portion 52a by bolts and extends forward.

[0030] The first arm portion 52a supports one contact portion 51 at a position lower than the second arm portion 52b. The second arm portion 52b supports one contact portion 51. Thereby, the plurality of contact portions 51 are supported by the support stay 52 at different positions in the vertical direction. And the plurality of contact portions 51 contact the side surface portion 32 of the fuel tank 30 at different positions in the vertical direction.

[0031] The pressing portion 60 presses the front surface portion 31 of the fuel tank 30 toward the partition plate 20. Such a pressing portion 60 has a band 61 and a tension adjuster 62. A pair of the band 61 and the tension adjuster 62 are provided on the left and right.

[0032] FIG. 9 is a perspective view of the tension adjuster 62 as viewed from the front. The tension adjuster 62 includes a mounting member 62a, a shaft member 62b, and a position adjusting member 62c. The mounting member 62a is attached to the opening 20a of the partition plate 20 by bolts, welding, or the like. The mounting member 62a is composed of, for example, an L-shaped metal fitting in side view. The mounting member 62a is provided with a hole (not shown) through which the shaft member 62b passes.

[0033] The front end of the band 61 is fixed to the shaft member 62b via a coupler 63 (see FIG. 7). The rear end of the band 61 is fixed to the pedal frame 70. The shaft member 62b is positioned through the opening 20a. The shaft member 62b has a shaft portion 62b1 that passes through the hole provided in the mounting member 62a. A thread is formed on the outer peripheral surface of the shaft portion 62b1.

[0034] The position adjusting member 62c moves the shaft member 62b forward and backward with respect to the mounting member 62a. Such a position adjusting member 62c is composed of, for example, a nut. The nut has a thread groove. The thread groove contacts and engages with the thread on the shaft portion 62b1 that has passed through the hole in the mounting member 62a. By rotating the nut, the shaft portion 62b1 can be moved forward and backward along its axial direction (the direction in which the shaft portion 62b1 extends) with respect to the mounting member 62a. That is, the axial position of the shaft member 62b with respect to the mounting member 62a can be adjusted. Thereby, the tension of the band 61 fixed to the shaft member 62b can be adjusted.

[0035] Fixing members 36 are fixed at two locations on the left and right of the upper surface portion 33 (see FIG. 6) of the fuel tank 30. FIG. 10 is a perspective view of the fixing member 36. Each fixing member 36 is elongated in the front-rear direction. The fixing member 36 has an insertion passage 36a. As shown in FIG. 11, the band 61 is inserted into the insertion passage 36a of the fixing member 36. That is, the fuel tank 30 is fixed to the upper surface portion 33 and has the fixing member 36 having the insertion passage 36a for the band 61. In the present embodiment, as shown in FIG. 7, the rear end of the band 61 is fixed to the pedal frame 70 at a position lower than the upper surface portion 33 of the fuel tank 30.

[0036] As described above, the band 61 is inserted into the insertion passage 36a of the fixing member 36, and the fixing member 36 is fixed to the upper surface portion 33 of the fuel tank 30. Therefore, when the tension of the band 61 is increased by the tension adjuster 62, in other words, when the band 61 is pulled in the direction approaching the partition plate 20, as shown in FIG. 12, the band 61 hits the rear end of the upper surface portion 33 of the fuel tank 30 and acts to lift the rear end of the upper surface portion 33 as it is (see the broken line portion in FIG. 12). Further, even if the band 61 does not hit the rear end of the upper surface portion 33 of the fuel tank 30, by pulling the band 61 inserted into the insertion passage 36a, the band 61 pushes up the rear end of the fixing member 36. Thereby, the front surface portion 31 of the fuel tank 30 can be pressed toward the partition plate 20.

[0037] In the present embodiment, the side surface portion 32 of the fuel tank 30 is supported by the side surface support portion 50 connected to the partition plate 20. In addition, the front surface portion 31 of the fuel tank 30 is pressed toward the partition plate 20 by the pressing portion 60. That is, in the present embodiment, the fuel tank 30 is supported not only by supporting the side surface portion 32 of the fuel tank 30 but also by pressing the fuel tank 30 against the thick and sturdy partition plate 20. Thereby, even when the fuel tank 30 disposed between the partition plate 20 and the steering column 10 is enlarged, the fuel tank 30 can be firmly supported within the dashboard 14.

[0038] Further, the plurality of contact portions 51 of the side surface support portion 50 contact the side surface portion 32 of the fuel tank 30 at different positions in the vertical direction (see FIG. 7). In this configuration, due to vibration or the like, it becomes difficult for the fuel tank 30 to rotate within a plane perpendicular to the vertical direction. Therefore, the support posture of the fuel tank 30 can be stabilized.

[0039] Further, the plurality of contact portions 51 are supported by the support stay 52. Both ends of the support stay 52 are connected to the partition plate 20 and the pedal frame 70, respectively. Therefore, the side surface portion 32 of the fuel tank 30 can be stably supported by the support stay 52 via the plurality of contact portions 51.

[0040] FIG. 13 is a perspective view of the partition plate 20 as viewed from the rear. A reinforcing frame 21 is fixed to the rear surface of the partition plate 20, that is, the surface of the partition plate 20 on the side of the steering column 10. That is, the tractor 1 includes a reinforcing frame 21 fixed to the partition plate 20. The reinforcing frame 21 extends in the vertical direction and is fixed to the partition plate 20 at two positions in the left-right direction. The reinforcing frame 21 is formed, for example, by bending a flat plate, but may be formed in a cylindrical shape (square tube) with a square cross section. By fixing the reinforcing frame 21 to the partition plate 20, the strength of the partition plate 20 can be increased. A hinge cover 23 is provided at the upper part of the partition plate 20. The hinge cover 23 covers a rotating shaft portion connected via the bonnet 5 (see FIG. 1) and a hinge (not shown).

[0041] A plurality of contact portions 22 are attached to the reinforcing frame 21. Specifically, a part (protrusion) of each contact portion 22 is fitted into a hole formed in the reinforcing frame 21 from the side of the fuel tank 30, whereby each contact portion 22 is attached to the reinforcing frame 21.

[0042] Each contact portion 22 is made of an elastic member (for example, rubber). In the present embodiment, two contact portions 22 are arranged side by side in the vertical direction in one reinforcing frame 21, but the number of contact portions 22 is not particularly limited.

[0043] FIG. 14 is a perspective view of the partition plate 20 with the fuel tank 30 supported by the tank support portion 40 as viewed from the front. FIG. 15 is a perspective view showing the state of FIG. 14 with the partition plate 20 removed. Each reinforcing frame 21 is located in a recess 31a of the front surface portion 31 of the fuel tank 30. At this time, the contact portion 22 attached to the reinforcing frame 21 contacts the front surface portion 31 (particularly, the portion facing within the recess 31a).

[0044] When the reinforcing frame 21 is positioned in the concave portion 31a of the front portion 31, when the fuel tank 30 is pressed against the partition plate 20 by the pressing portion 50 of the tank support portion 40, the fuel tank 30 is properly positioned with respect to the partition plate 20, and the positional deviation of the fuel tank 30 with respect to the partition plate 20 can be reduced. Thereby, the support posture of the fuel tank 30 can be stabilized.

[0045] Also, as shown in FIG. 15, the above-described tank support portion 40 has a bottom surface support portion 80. The bottom surface support portion 80 supports the bottom surface portion 34 of the fuel tank 30. The bottom surface support portion 80 includes a fixing plate 81, a bracket 82, and a spacer 83. The bottom portion of the partition plate 20 is fixed to the fixing plate 81 (see FIG. 13). The bracket 82 is located on the fixing plate 81 and supports the bottom surface portion 34 of the fuel tank 30. The spacer 83 is located on the transmission case 13 and supports the fixing plate 81.

[0046] Due to the positional relationship of the fixing plate 81, the bracket 82, and the spacer 83 as described above, the bottom surface support portion 80 is supported by the transmission case 13. Therefore, it can be said that the fuel tank 30 supported by the bottom surface support portion 80 is supported by the transmission case 13 via the bottom surface support portion 80. In this way, since the fuel tank 30 is supported by the strong transmission case 13 via the bottom surface support portion 80, the support of the fuel tank 30 can be made more stable.

[0047] FIG. 16 is a perspective view when the left front portion of the driver's seat 7 of the tractor 1 is viewed from the rear. A mudguard frame MF is fixed to the floor surface portion 7a of the driver's seat 7 where the steering column 10 is located. The mudguard frame MF is a frame-shaped frame that supports a mudguard (mud guard) MG. In the present embodiment, a handrail frame HF is connected to the upper portion of the mudguard frame MF. The handrail frame HF is a frame that is gripped by the driver when getting on and off the driver's seat 7, and is installed for the purpose of assisting the driver in getting on and off and promoting safe getting on and off.

[0048] Incidentally, the handrail frame HF may be directly fixed to the floor portion 7a of the driver's seat 7 without passing through the mudguard frame MF. Also, both the mudguard frame MF and the handrail frame HF may be separately fixed to the floor portion 7a. Further, only one of the mudguard frame MF and the handrail frame HF may be provided on the tractor 1 and fixed to the floor portion 7a. Also, the mudguard frame MF may be formed larger than the mudguard MG, and only a part of the outer periphery of the mudguard MG may be supported by the mudguard frame MF. In the mudguard frame MF, a frame portion that does not support the mudguard MG may be used as the handrail frame HF. In any case, it can be said that in the tractor 1 of the present embodiment, at least one of the mudguard frame MF and the handrail frame HF is fixed to the floor portion 7a of the driver's seat 7.

[0049] In the present embodiment, the mudguard frame MF is connected to the side support portion 50 (see FIG. 7) of the tank support portion 40 via the connecting stay 90. More specifically, it is as follows.

[0050] FIG. 17 is a perspective view showing the left front portion of the driver's seat 7 of the tractor 1 with the mudguard frame MF and the handrail frame HF removed. FIG. 18 is a perspective view of the connecting stay 90. The connecting stay 90 is configured by connecting three flat plate portions, that is, a first flat plate portion 90a, a second flat plate portion 90b, and a third flat plate portion 90c, and is formed in a shape obtained by bending a single flat plate as a whole.

[0051] The first flat plate portion 90a and the second flat plate portion 90b are flat plates extending in the vertical direction. The first flat plate portion 90a is positioned offset upward with respect to the second flat plate portion 90b. As shown in FIG. 3, the second flat plate portion 90b is positioned inside the first flat plate portion 90a in the left-right direction, that is, on the side closer to the fuel tank 30. The first flat plate portion 90a and the second flat plate portion 90b are positioned along the side surface portion 32 of the fuel tank 30.

[0052] As shown in FIG. 18, the third flat plate portion 90c is a flat plate extending in the horizontal direction (left - right direction), and connects the lower end edge of the first flat plate portion 90a and the upper end edge of the second flat plate portion 90b.

[0053] In the second flat plate portion 90b, a first through - hole H1 and a second through - hole H2 are formed. The first through - hole H1 and the second through - hole H2 are positioned side by side in the front - rear direction in the second flat plate portion 90b. Bolts B1 and B2 shown in FIG. 3 are respectively inserted into the first through - hole H1 and the second through - hole H2. The bolts B1 and B2 pass through the first through - hole H1 and the second through - hole H2 of the second flat plate portion 90b shown in FIG. 18, and further pass through stay holes 52h1 and 52h2 provided in the first arm portion 52a of the support stay 52 shown in FIG. 7, and are respectively fastened with nuts (not shown). Thereby, the connecting stay 90 is fixed to the support stay 52. In FIG. 7, the region surrounded by the broken line is the portion where the second flat plate portion 90b of the connecting stay 90 contacts. Hereinafter, the above - mentioned region is also referred to as the fixed portion 52a1.

[0054] In the first flat plate portion 90a shown in FIG. 18, a third through - hole H3 and a fourth through - hole H4 are formed. The third through - hole H3 and the fourth through - hole H4 are positioned side by side in the up - down direction in the first flat plate portion 90a. Bolts B3 and B4 shown in FIG. 16 are respectively inserted into the third through - hole H3 and the fourth through - hole H4. After the bolts B3 and B4 are respectively inserted into holes (not shown) provided in the vertical frame VF which forms a part of the mud guard frame MF, they pass through the third through - hole H3 and the fourth through - hole H4 of the first flat plate portion 90a shown in FIG. 18, and are respectively fastened with nuts (not shown). The above - mentioned vertical frame VF refers to the portion of the mud guard frame MF where the lower end portion is fixed to the floor surface portion 7a and extends upward.

[0055] When the above bolts B3 and B4 are fastened with nuts, the mudguard frame MF is fixed to the connecting stay 90. That is, the mudguard frame MF is connected to the side support portion 50 (see FIG. 7) having the support stay 52 via the connecting stay 90. Note that instead of the mudguard frame MF, a handrail frame HF may be connected to the side support portion 50 via the connecting stay 90.

[0056] Thus, the tractor 1 of the present embodiment includes a connecting stay 90 that connects the mudguard frame MF or the handrail frame HF and the side support portion 50. In this configuration, the side support portion 50 is fixed to the floor surface portion 7a of the driver's seat 7 via the connecting stay 90 and the mudguard frame MF (or the handrail frame HF). Thereby, the support of the fuel tank 30 by the side support portion 50 can be made more stable.

[0057] FIG. 19 is a perspective view of the dashboard 14 of the tractor 1 as viewed from the rear. The dashboard 14 in which the fuel tank 30 is disposed inside has an upper cover 141U and a lower cover 141D. The upper cover 141U and the lower cover 141D are arranged side by side in the vertical direction. More specifically, the upper cover 141U is located above the lower cover 141D. The upper cover 141U and the lower cover 141D constitute the first cover 14 shown in FIG. 2.

[0058] FIG. 20 is a perspective view of the lower cover 141D. The lower cover 141D has a notch N at its upper edge. The above-described connecting stay 90 is positioned through the notch N of the lower cover 141D. That is, the connecting stay 90 is connected to the side support portion 50 (the fixed portion 52a1 in FIG. 7) through the notch N of the lower cover 141D. Note that the upper cover 141U may have a notch and the connecting stay 90 may be positioned through the notch of the upper cover 141U. Further, both the upper cover 141U and the lower cover 141D may have notches, and the connecting stay 90 may be positioned through one opening formed by combining both notches.

[0059] As described above, in this embodiment, at least one of the upper cover 141U and the lower cover 141D has a notch (for example, notch N). And the connecting stay 90 is positioned through the notch. Thereby, for example, with the side support portion 50 and the mudguard frame MF (or the handrail frame HF) previously connected by the connecting stay 90, the upper cover 141U can be attached to and detached from the vehicle body 2, or the lower cover 141D can be attached to and detached from the vehicle body 2. Therefore, the workability of attaching and detaching the upper cover 141U and the like is improved.
