Such a side support part 50 has a plurality of contact parts 51 and a support stay 52.

Each contact portion 51 is made of an elastic member (for example, rubber) that contacts the side surface portion 32 of the fuel tank 30 . The plurality of contact parts 51 are supported by a support stay 52. Specifically, a portion (convex portion) 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 this embodiment, two contact parts 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.

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 a pedal frame 70. FIG. 8 is a perspective view of the pedal frame 70. Note that in FIGS. 6 and 7, only a part of the pedal frame 70 (the part connected to the support stay 52) is shown for convenience. 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.

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 32 of the fuel tank 30, bends upward, and then further bends and extends rearward. The second arm 52b is fixed to the upper part of the first arm 52a with a bolt and extends forward.

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 parts 51 are supported by the support stay 52 at different positions in the vertical direction. The plurality of contact portions 51 contact the side surface portion 32 of the fuel tank 30 at different positions in the vertical direction.

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

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

The front end of the band 61 is fixed to the shaft member 62b via a connector 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 62b ₁ that passes through the hole provided in the mounting member 62a. A thread is formed on the outer peripheral surface of the shaft portion 62b ₁ .

The position adjustment member 62c moves the shaft member 62b forward and backward with respect to the mounting member 62a. Such a position adjustment member 62c is composed of, for example, a nut. The nut has a thread groove. The thread groove contacts and engages with the thread of the shaft portion 62b ₁ that has passed through the hole of the mounting member 62a. By rotating the nut, the shaft portion 62b ₁ can be moved forward and backward with respect to the mounting member 62a along its axial direction (the direction in which the shaft portion 62b ₁ extends). 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.

Fixing members 36 are fixed to two locations on the left and right sides 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. The band 61 is inserted into the insertion passage 36a of the fixing member 36, as shown in FIG. That is, the fuel tank 30 has a fixing member 36 that is fixed to the upper surface portion 33 and has an insertion passage 36a for the band 61. In this 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 33 of the fuel tank 30.

As described above, the band 61 is inserted through the insertion passage 36a of the fixing member 36, and the fixing member 36 is fixed to the upper surface 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 a direction approaching the partition plate 20, the band 61 is moved toward the upper surface of the fuel tank 30, as shown in FIG. 33 and acts to lift the rear end of the upper surface portion 33 (see the broken line 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, the band 61 pushes up the rear end of the fixing member 36 by pulling the band 61 inserted through the insertion passage 36a. Thereby, the front part 31 of the fuel tank 30 can be pressed toward the partition plate 20.

In this embodiment, the side surface portion 32 of the fuel tank 30 is supported by a side surface support portion 50 connected to the partition plate 20 . In addition, the front portion 31 of the fuel tank 30 is pressed toward the partition plate 20 by the pressing portion 60. That is, in this embodiment, the fuel tank 30 is supported not only by the support of 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 if the fuel tank 30 disposed between the partition plate 20 and the steering column 10 becomes larger, the fuel tank 30 can be firmly supported within the dashboard 14.

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

Further, the plurality of contact portions 51 are supported by a 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 .

FIG. 13 is a perspective view of the partition plate 20 when 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 steering column 10 side. 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 and right directions. The reinforcing frame 21 is formed, for example, by bending a flat plate, but may also 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. Note that a hinge cover 23 is provided on the upper part of the partition plate 20. The hinge cover 23 covers a rotation shaft portion connected to the bonnet 5 (see FIG. 1) via a hinge (not shown).

A plurality of contact parts 22 are attached to the reinforcing frame 21. Specifically, a portion (convex portion) of each contact portion 22 is fitted into a hole formed in the reinforcing frame 21 from the fuel tank 30 side, thereby attaching each contact portion 22 to the reinforcing frame 21.

Each contact portion 22 is made of an elastic member (for example, rubber). In this embodiment, two contact portions 22 are attached vertically side by side in one reinforcing frame 21, but the number of contact portions 22 is not particularly limited.

FIG. 14 is a perspective view of the partition plate 20 in which the fuel tank 30 is supported by the tank support portion 40, when 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 part 31 of the fuel tank 30, respectively. At this time, the contact portion 22 attached to the reinforcing frame 21 comes into contact with the front portion 31 (particularly the portion facing each other within the recess 31a).

By positioning the reinforcing frame 21 in the recess 31a of the front part 31, when the fuel tank 30 is pressed against the partition plate 20 by the pressing part 50 of the tank support part 40, the fuel tank 30 can be properly pressed against the partition plate 20. The positioning of the fuel tank 30 with respect to the partition plate 20 can be reduced. Thereby, the supporting posture of the fuel tank 30 can be stabilized.

Further, as shown in FIG. 15, the tank support section 40 described above has a bottom support section 80. The bottom support part 80 supports the bottom part 34 of the fuel tank 30. The bottom support portion 80 includes a fixing plate 81, a bracket 82, and a spacer 83. The bottom of the partition plate 20 is fixed to the fixed plate 81 (see FIG. 13). The bracket 82 is located on the fixed plate 81 and supports the bottom part 34 of the fuel tank 30. Spacer 83 is located on mission case 13 and supports fixed plate 81.

The bottom support portion 80 is supported by the mission case 13 due to the positional relationship of the fixing plate 81, the bracket 82, and the spacer 83. Therefore, it can be said that the fuel tank 30 supported by the bottom support part 80 is supported by the mission case 13 via the bottom support part 80. In this way, the fuel tank 30 is supported by the strong mission case 13 via the bottom support part 80, so that the support of the fuel tank 30 can be made more stable.

FIG. 16 is a perspective view of the left front portion of the driver's seat 7 of the tractor 1, viewed from the rear. A mudguard frame MF is fixed to the floor 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 the mudguard MG. In this embodiment, a handrail frame HF is connected to the upper part of the mudguard frame MF. The handrail frame HF is a frame that is held 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.

Note that the handrail frame HF may be directly fixed to the floor surface portion 7a of the driver's seat 7 without intervening the mudguard frame MF. Further, both the mudguard frame MF and the handrail frame HF may be separately fixed to the floor surface portion 7a. Furthermore, only one of the mudguard frame MF and the handrail frame HF may be provided on the tractor 1 and fixed to the floor surface portion 7a. Further, the mudguard frame MF is formed larger than the mudguard MG, and only a part of the outer periphery of the mudguard MG is supported by the mudguard frame MF, and the frame portion of the mudguard frame MF that does not support the mudguard MG is used as a handrail frame HF. Any configuration may be used. In any case, it can be said that in the tractor 1 of this embodiment, at least one of the mudguard frame MF and the handrail frame HF is fixed to the floor surface portion 7a of the driver's seat 7.

In this embodiment, the mudguard frame MF is connected to the side support part 50 (see FIG. 7) of the tank support part 40 via the connection stay 90. A more detailed explanation is as follows.

FIG. 17 is a perspective view showing the left front part of the driver's seat 7 of the tractor 1 with the mudguard frame MF and handrail frame HF removed. Moreover, FIG. 18 is a perspective view of the connection stay 90. The connecting stay 90 is configured by connecting three flat plate parts, that is, a first flat plate part 90a, a second flat plate part 90b, and a third flat plate part 90c, and is formed as a whole by bending one flat plate. be done.

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 part 90a is positioned upwardly shifted from the second flat plate part 90b. As shown in FIG. 3, the second flat plate part 90b is located inside the first flat plate part 90a, that is, closer to the fuel tank 30 in the left-right direction. The first flat plate portion 90a and the second flat plate portion 90b are located along the side surface 32 of the fuel tank 30.

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

A first through hole H1 and a second through hole H2 are formed in the second flat plate portion 90b. The first through hole H1 and the second through hole H2 are located side by side in the front-rear direction in the second flat plate portion 90b. Bolts B1 and B2 shown in FIG. 3 are inserted into the first through hole H1 and the second through hole H2, respectively. The bolts B1 and B2 pass through the first through hole H1 and the second through hole H2 of the second flat plate part 90b shown in FIG. 18, and are further provided in the first arm part 52a of the support stay 52 shown in FIG. They are inserted into the stay holes 52h ₁ and 52h ₂ and fastened with nuts (not shown), respectively. Thereby, the connecting stay 90 is fixed to the support stay 52. In addition, in FIG. 7, the area surrounded by the broken line is the part with which the second flat plate part 90b of the connecting stay 90 comes into contact. Hereinafter, the above region will also be referred to as the fixed portion 52a ₁ .

A third through hole H3 and a fourth through hole H4 are formed in the first flat plate portion 90a shown in FIG. 18. The third through hole H3 and the fourth through hole H4 are located side by side in the vertical direction in the first flat plate portion 90a. Bolts B3 and B4 shown in FIG. 16 are inserted into the third through hole H3 and the fourth through hole H4, respectively. After the bolts B3 and B4 are inserted into holes (not shown) provided in the vertical frame VF that constitutes a part of the mudguard frame MF, the bolts B3 and B4 are inserted into the third through holes of the first flat plate portion 90a shown in FIG. 18. H3 and the fourth through hole H4, and are fastened with nuts (not shown), respectively. Note that the above-mentioned vertical frame VF refers to a portion of the mudguard frame MF whose lower end portion is fixed to the floor surface portion 7a and extends upward.

The mudguard frame MF is fixed to the connecting stay 90 by fastening the bolts B3 and B4 with nuts. That is, the mudguard frame MF is connected to the side support portion 50 (see FIG. 7) having the support stay 52 via the connection 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 connection stay 90.

In this way, the tractor 1 of this embodiment includes the connection 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 portion 7a of the driver's seat 7 via the connection stay 90 and the mudguard frame MF (or handrail frame HF). Thereby, the support of the fuel tank 30 by the side support portion 50 can be made more stable.

FIG. 19 is a perspective view of the dashboard 14 of the tractor 1 viewed from the rear. The dashboard 14 in which the fuel tank 30 is disposed has an upper cover 141U and a lower cover 141D. The upper cover 141U and the lower cover 141D are located 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.

FIG. 20 is a perspective view of the lower cover 141D. The lower cover 141D has a notch N at the upper edge. The above-mentioned connecting stay 90 is located through the notch N of the lower cover 141D. That is, the connecting stay 90 is connected to the side support portion 50 (fixed portion 52a ₁ 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. Alternatively, both the upper cover 141U and the lower cover 141D may have a notch, and the connecting stay 90 may be located through one opening formed by combining both the notches.

Thus, in this embodiment, at least one of the upper cover 141U and the lower cover 141D has a cutout (for example, the cutout N). The connecting stay 90 is positioned through the notch. As a result, for example, with the side support portion 50 and the mudguard frame MF (or handrail frame HF) connected first with the connection stay 90, the upper cover 141U can be attached to and removed from the vehicle body 2, or the lower part can be attached to and removed from the vehicle body 2. The cover 141D can be attached and removed. Therefore, the workability of attaching and removing the upper cover 141U and the like is improved. For example, after attaching the lower cover 141D to the vehicle body 2, the side support portion 50 and the mudguard frame MF (or handrail frame HF) are connected with the connecting stay 90 passing through the notch portion N, and then the upper cover 141D is attached to the vehicle body 2. The installation work can be performed in the order of attaching the cover 141U, and the removal work can also be performed in the reverse order.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and can be expanded or modified without departing from the gist of the invention.
