  First, the tractor 1 will be briefly described. The technical idea of the present invention can be applied to other agricultural machine vehicles and construction machine vehicles.

  FIG. 1 shows a tractor 1. In the figure, the front-rear direction and the vertical direction of the tractor 1 are shown.

  The tractor 1 mainly includes a frame 11, an engine 12, a transmission 13, a front axle 14, and a rear axle 15. The tractor 1 is provided with a cabin 2.

  The frame 11 forms a skeleton of the tractor 1. An engine 12 and the like described below are attached to the frame 11.

  The engine 12 converts energy obtained by burning fuel into rotational motion. When the operator operates the accelerator pedal 16, the engine 12 changes the driving state in accordance with the operation. Further, the engine 12 maintains the rotation speed constant even when the load changes.

  The transmission 13 performs forward / reverse switching and shifting of the tractor 1. When the operator operates the shift lever 17, the transmission 13 changes its operating state according to the operation. The transmission 13 includes a hydraulic-mechanical continuously variable transmission (HMT or iHMT) as a transmission.

  The front axle 14 transmits the rotational power of the engine 12 to the front tire 141. The rotational power of the engine 12 is input to the front axle 14 via the transmission 13. The front axle 14 is provided with a steering device. When the operator operates the handle 18, the steering device changes the steering angle of the front tire 141 according to the operation.

  The rear axle 15 transmits the rotational power of the engine 12 to the rear tire 151. The rotational power of the engine 12 is input to the rear axle 15 via the transmission 13. The rear axle 15 is provided with a PTO output mechanism. The PTO output mechanism inputs rotational power to the towing work machine.

  The cabin 2 constitutes the cockpit of the tractor 1. The cabin 2 covers a number of controls in addition to the accelerator pedal 16, the shift lever 17, and the handle 18. The cabin 2 covers the driver seat 19. The operator enters the cabin 2 and steers while sitting on the driver's seat 19.

  The tractor 1 has a feature that levers operated by an operator are arranged on the armrest 110. Thereby, the operability of the tractor 1 is improved. Further, the tractor 1 can adjust the angle and height of the handle 18 (see arrows a and h). Thereby, the tractor 1 has improved comfort.

  Next, the cabin 2 will be described in detail.

  FIG. 2 shows the cabin 2. FIG. 3 shows the frame structure of the cabin 2. In the figure, the front-rear direction, the up-down direction, and the left-right direction of the tractor 1 are represented.

  The cabin 2 mainly includes a floor plate 21, a fender plate 22, a front pillar 23, and a rear pillar 24. Further, the cabin 2 includes a roof 3.

  The floor plate 21 is a part of the bottom surface of the cabin 2. The left floor plate 21 is attached to the upper surface of the lower frame 25. The right floor plate 21 is also attached to the upper surface of the lower frame 25. The left and right floor plates 21 are connected to each other via an air cut plate 26 and the like. The front plate 27 is formed in a straight line and is fixed along the front surface of each floor plate 21. The side plate 28 is formed in a straight line and is fixed along the side surface of each floor plate 21. The side plate 28 constitutes a part of a door frame (a frame in which the side glass 53 serving as the door 4 is accommodated). In the tractor 1, the substep 29 is fixed to the side plate 28.

  The fender plate 22 is a part of the side surface of the cabin 2. A lower end portion of the left fender plate 22 is attached to the lower frame 25. The right fender plate 22 is also attached to the lower frame 25 at its lower end. The left and right fender plates 22 are connected to each other via a rear frame 210 and the like. The seal plate 211 is formed in an arc shape and is fixed along the upper surface of each fender plate 22. The seal plate 211 constitutes a part of a door frame (a frame in which the side glass 53 serving as the door 4 is accommodated). In the tractor 1, a gas damper (not shown) is fixed to the seal plate 211.

  The front pillar 23 supports the front end portion of the roof 3 serving as the top surface. The lower end of the left front pillar 23 is attached to the floor plate 21. The right front pillar 23 is also attached to the floor plate 21 at its lower end. The left and right front pillars 23 are connected to each other via a front beam 212. Further, each front pillar 23 is also connected to a rear pillar 24 via a side beam 213. The front pillar 23 constitutes a part of a door frame (a frame in which the side glass 53 serving as the door 4 is accommodated). Note that both ends of the windshield 51 are fixed to the left and right front pillars 23. In the tractor 1, a side mirror 214 is fixed to the front pillar 23 via a stay 214S. Further, the work lamp 215 and the winker 216 are also fixed to the front pillar 23.

  The rear pillar 24 supports the rear end portion of the roof 3 serving as the top surface. The lower end of the left rear pillar 24 is attached to the fender plate 22. The lower end of the right rear pillar 24 is also attached to the fender plate 22. The left and right rear pillars 24 are connected to each other via a rear beam 217. Further, each rear pillar 24 is also connected to the front pillar 23 via a side beam 213. The rear pillar 24 constitutes a part of a door frame (a frame in which the side glass 53 serving as the door 4 is accommodated). Note that both ends of the rear glass 52 are fixed to the left and right rear pillars 24. In the tractor 1, the hinge 41 of the door 4 is also fixed to the rear pillar 24.

  Here, the first feature in the present frame structure will be described.

  4 is a view as seen from the direction of the arrow X shown in FIG. In the figure, the front-rear direction and the vertical direction of the tractor 1 are shown.

  As a first feature of the frame structure, a seal plate 211 is fixed to the fender plate 22. And the dimension H from a lower edge to an upper edge becomes large gradually as the seal plate 211 goes back. Further, the seal plate 211 is welded to the rear pillar 24 at the rear end thereof. In other words, the height H of the seal plate 211 gradually increases as it approaches the rear pillar 24 and is fixed to the rear pillar 24. Thereby, the seal plate 211 functions as a rib. Therefore, the lodging strength of the rear pillar 24 can be increased. As a result, the strength of the cabin 2 can be increased.

  In addition, the seal plate 211 has an upper edge shape (see the two-dot chain line U) of the seal plate 211 that is perpendicular or substantially perpendicular to the front edge shape (see the two-dot chain line F) of the rear pillar 24. Thereby, since the seal plate 211 effectively functions as a rib, the strength of the cabin 2 can be further increased.

  Next, the second feature in this frame structure will be described.

  FIG. 5 is a view seen from the direction of the arrow Y shown in FIG. In the figure, the front-rear direction and the left-right direction of the tractor 1 are shown.

  As a second feature of the frame structure, a sub-step 29 is fixed to the side plate 28. The sub-step 29 is arranged so that the operator can go up obliquely backward. That is, the substep 29 is arranged obliquely rearward. As a result, the moving direction when the operator gets on is obliquely rearward. Therefore, the operator can be guided inward. As a result, it is possible to make the cabin 2 easy to get on.

  In addition, the sub-step 29 is arranged so that the flow line L of the sub-step 29 faces the driver seat 19 or near the front side of the driver seat 19. Thereby, since an operator can be guide | induced to the driver's seat 19, it becomes possible to make the cabin 2 into which it gets in more easily.

  In this regard, it can be said that the sub-step 29 is arranged so that the flow line L of the sub-step 29 faces between the steering wheel 18 and the driver seat 19. As a result, the operator can easily dodge the handle 18, and the operator can be guided to the driver seat 19.

  Next, the third to fifth features in this frame structure will be described.

  6 is a view as seen from the direction of the arrow Z shown in FIG. In the figure, the front-rear direction and the vertical direction of the tractor 1 are shown.

  As a third feature of this frame structure, the front pillar 23 and the rear pillar 24 are connected by a side beam 213. The side beam 213 is formed in a mountain shape. That is, the side beam 213 is formed so that the central portion of the side beam 213 is warped upward. Thereby, the area of the side glass 53 becomes large. Therefore, the field of view of the operator can be widened. As a result, comfort can be improved.

  As a fourth feature of this frame structure, the front pillar 23 protrudes upward from the side beam 213 (see arrow J). The front beam 212 is welded to the upper end portion of the front pillar 23. Thereby, the area of the windshield 51 becomes large. Therefore, the field of view of the operator can be widened. As a result, comfort can be improved.

  As a fifth feature of the present frame structure, the rear beam 217 is welded to a portion slightly lower than the upper end portion of the rear pillar 24. This is because the air conditioning unit 61 is mounted above the rear beam 217 (see FIG. 13). Thereby, the space in the cabin 2 becomes wide. Therefore, the operator's feeling of pressure can be reduced. As a result, comfort can be improved.

  Next, the sixth feature of the present frame structure will be described.

  FIG. 7 is an enlarged view of regions Ra and Rb shown in FIG. FIG. 8 shows a direction in which a load is applied when the frame structure is lifted. The arrow Pl represents a load applied to the eyebolt Be when the frame structure is lifted. An arrow Pa represents a load transmitted from the side beam 213 to the front pillar 23. An arrow Pb represents a load transmitted from the side beam 213 to the rear pillar 24.

  A sixth feature of the frame structure is that a bolt base 218 is fixed to the side beam 213. More specifically, a bolt base 218 is fixed to the central portion of the side beam 213. That is, the bolt base 218 is arranged at the top of the side beam 213 or in the vicinity of the top. The bolt base 218 is provided with a screw hole 218h, and the eyebolt Be can be attached to and detached from the screw hole 218h. Thereby, when this frame structure is lifted, the load is not concentrated on either the front pillar 23 or the rear pillar 24. That is, the load can be distributed to the front pillar 23 and the rear pillar 24.

  Further, the bolt base 218 is disposed slightly behind the center of gravity of the frame structure. Accordingly, when the frame structure is lifted, the forward tilting posture (the posture in which the front side is lowered) is adopted, and therefore, the work of attaching the frame structure to the vehicle body is facilitated. More specifically, after the front pillar 23 is supported by the floor plate 21, the rear pillar 24 is supported by the fender plate 22, thereby facilitating the mounting operation. Such a feature can be obtained even when the frame structure is preliminarily equipped (equipment attachment work).

  Next, the roof 3 will be described in detail.

  FIG. 9 shows the top surface of the roof 3. FIG. 10 shows the lower surface of the roof 3. FIG. 11 shows the side surface of the roof 3. FIG. 12 shows a cross section of the roof 3. FIG. 13 shows the internal structure of the roof 3. In the figure, the front-rear direction, the up-down direction, and the left-right direction of the tractor 1 are represented.

  The roof 3 includes an outer panel 31, an inner panel 32, and a side panel 33. The roof 3 houses an audio device 34 and the like therein. Further, the roof 3 houses an air conditioning system 6 therein.

  The outer panel 31 is provided with openings 31a and 31b. The opening 31a is provided in accordance with the shape of the skylight 3S, and becomes a passage for outside air or inside air when the skylight 3S is opened. That is, the opening 31a allows the air in the cabin 2 to be replaced. The opening 31b is provided immediately above the bolt base 218 so that the eye bolt Be can be attached to the bolt base 218.

  The outer panel 31 has a conical bulge formed on the front side of the opening 31a. The work lamp 22 is fitted inside the bulge. The work lamp 31L illuminates the front to enable night work and the like.

  The inner panel 32 is provided with openings 32a and 32b. The opening 32a is provided directly below the skylight 3S, and becomes a passage for outside air or inside air when the skylight 3S is opened. In other words, the opening 32a allows the air in the cabin 2 to be replaced. The opening 32b is provided directly below the soundproofing material (urethane) 35 so that a part of the soundproofing material 35 can be seen.

  In the inner panel 32, the controller 6C of the air conditioning system 6 is disposed on the right side of the opening 32b. An audio device 34 is disposed on the left side of the opening 32b. Further, air outlets 32c and 32d are arranged on the front side of the opening 32a and on both the left and right sides of the opening 32b. The air outlet 32c is provided so that air can be blown toward the windshield 51 and the side glass 53 in order to prevent fogging. The air outlet 32d is provided so that air can be blown toward the operator in order to improve comfort.

  The side panel 33 is provided with a suction port 33a. A duct (not shown) is connected to the suction port 33a and serves as a passage for outside air supplied to the air conditioning system 6. That is, the suction port 33 a is an outside air introduction port of the air conditioning system 6.

  Here, the air conditioning system 6 will be described in detail.

  The air conditioning system 6 includes an air conditioning unit 61 and an air conditioning duct 62.

  The air conditioning unit 61 includes a sirocco fan, an evaporator, a heater, and the like. The air conditioning unit 61 has a front end supported by a rear beam 217 and a rear end supported by a bracket 219. The bracket 219 is fixed to the rear beam 217.

  More specifically, the bracket 219 is fixed to the rear beam 217 and protrudes rearward from the rear beam 217. The air conditioning unit 61 is supported by the rear beam 217 and the bracket 219. At this time, the air conditioning unit 61 is disposed across the rear beam 217. That is, the air conditioning unit 61 is placed on the rear beam 217, a part of the air conditioning unit 61 protrudes forward of the rear beam 217 (see La in FIG. 14), and a part of the air conditioning unit 61 protrudes rearward of the rear beam 217. It arrange | positions in a state (refer Lb in FIG. 14).

  The air conditioning unit 61 is housed in the casing 63. The casing 63 is provided with an intake portion 63a at the upper left and a discharge portion 63b at the front. Further, a partition plate 64 is disposed on the right side of the air conditioning unit 61, and a switching device 65 is disposed on the left side of the air conditioning unit 61. These are covered by an undercover.

  The switching device 65 includes a motor 66, an arm 67, a rod 68, a shutter 69, and the like. That is, the switching device 65 is configured such that the motor 66 can rotate the shutter 69 via the arm 67 and the rod 68. Thus, the switching device 65 can switch between a state in which outside air is guided to the air conditioning unit 61 and a state in which inside air is guided to the air conditioning unit 61. The switching device 65 can adjust the ratio of the outside air and the inside air guided to the air conditioning unit 61.

  The air conditioning duct 62 guides the adjusted air whose temperature is adjusted by the air conditioning unit 61. The air conditioning duct 62 branches in two directions so as to surround the audio device 34 and the like. Hereinafter, the air conditioning duct 62 will be described in detail.

  FIG. 14 is an enlarged view of a part of the air conditioning system 6. In addition, the arrow A in the figure indicates the flow direction of the adjustment air. In the figure, the front-rear direction and the left-right direction of the tractor 1 are shown.

  The air conditioning duct 62 includes a right air duct 62R that guides the adjusted air to the right outlets 32c and 32d, and a left air duct 62L that guides the adjusted air to the left outlets 32c and 32d. The air-conditioning duct 62 includes a connection duct 62C that guides the adjustment air from the discharge part 63b of the casing 63 to the air blowing ducts 62L and 62R.

  The connecting duct 62 </ b> C is a T-shaped branch pipe in plan view that branches right and left. The connection duct 62C is formed by connecting a long pipe portion 62Ca that is parallel to the left-right direction and a short pipe portion 62Cb that is parallel to the front-rear direction. Both the long tube portion 62Ca and the short tube portion 62Cb have a rectangular cross section.

  With such a configuration, the adjustment air sent out from the air conditioning unit 61 flows into the long pipe portion 62Ca through the short pipe portion 62Cb. And adjustment air collides with front wall 62Cw of long pipe part 62Ca, and is divided into two. Thus, one adjustment air flows into the right air duct 62R, and the other adjustment air flows into the left air duct 62L.

  In addition, the front wall 62Cw of the long pipe portion 62Ca is provided with a protrusion 62Cp having a V-shaped cross section that protrudes rearward. The protrusion 62Cp is disposed so as to face the flow direction of the adjustment air that has flowed into the long pipe portion 62Ca. For this reason, the adjustment air that has flowed into the long pipe portion 62Ca is reliably distributed to the right air duct 62R and the left air duct 62L. Note that the right and left air volume distribution can be easily adjusted by simply changing the protruding height, opening angle, position, and the like of the protrusion 62Cp.

  Further, the right air duct 62R will be described in detail. The right air duct 62R includes a rear bent pipe part 62Ra, a right branch part 62Rb, and a front bent pipe part 62Rc along the flow direction of the adjustment air. (See FIG. 13). The rear bent pipe portion 62Ra guides the adjusted air branched in the connection duct 62C to the right branch portion 62Rb. Note that the above-described air outlet 32d is provided in the right diversion portion 62Rb. Further, the above-described air outlet 32c is provided in the front bent pipe portion 62Rc. The air outlets 32c and 32d are provided with fins 32cf and 32df that can freely change the air volume and direction of the adjusted air (see FIGS. 10, 13, and 15).

  Similarly, the left air duct 62L will be described in detail. The left air duct 62L includes a rear bent pipe portion 62La, a left branch portion 62Lb, and a front bent pipe portion 62Lc along the flow direction of the adjusted air. (See FIG. 13). The rear bent pipe portion 62La guides the adjusted air branched in the connection duct 62C to the left branch portion 62Lb. Note that the above-described air outlet 32d is provided in the left branch portion 62Lb. Further, the above-described air outlet 32c is provided in the front bent pipe portion 62Lc. The air outlets 32c and 32d are provided with fins 32cf and 32df that can freely change the air volume and direction of the adjusted air (see FIGS. 10, 13, and 16).

  Hereinafter, the right branch part 62Rb and the left branch part 62Lb will be described in detail.

  FIG. 15 shows a flow path structure of the right branch part 62Rb. FIG. 15A shows the upper surface of the right branch portion 62Rb, and FIG. 15B shows its internal structure. FIG. 16 shows the flow path structure of the left branch portion 62Lb. FIG. 16A shows the upper surface of the left branch portion 62Lb, and FIG. 16B shows its internal structure. In addition, the arrow A in the figure indicates the flow direction of the adjustment air.

  The right branch portion 62Rb includes a support plate 71 and a cover member 72. The support plate 71 constitutes the right side surface of the right branch part 62Rb. Further, the cover member 72 constitutes the upper and lower surfaces and the left side surface of the right flow dividing portion 62Rb so as to sandwich the support plate 71 from the inside.

  The cover member 72 includes a top plate portion 721, a bottom plate portion 722, and an inclined plate portion 723. Both the top plate portion 721 and the bottom plate portion 722 are provided horizontally. The inclined plate portion 723 connects the inner sides of the top plate portion 721 and the bottom plate portion 722 and is inclined obliquely downward to the right. The inclined plate portion 723 is provided with an air outlet 32d.

  More specifically, an attachment portion formed by bending the right edge portion of the top plate portion 721 upward is fastened to the upper edge portion of the support plate 71 by a bolt B1. Further, the attachment portion formed by bending the lower edge portion of the support plate 71 outward is fastened to the right edge portion of the bottom plate portion 722 by a bolt B2. In this way, the cylindrical right branch part 62Rb is constructed.

  With such a structure, the right branch portion 62Rb can be disassembled simply by removing the bolts B1 and B2. As a result, the right branch part 62Rb can be easily removed from the rear bent pipe part 62Ra and the front bent pipe part 62Rc constituting the right air duct 62R. On the contrary, the right diverting part 62Rb can be assembled only by attaching the bolts B1 and B2. As a result, the right branch portion 62Rb can be easily attached to the rear bent pipe portion 62Ra and the front bent pipe portion 62Rc constituting the right air duct 62R.

  Further, stays 711 and 712 are provided on the upper edge portion of the support plate 71 inward. A hanging tool is attached to the stay 711, and a wire 91 that passes between the top plate 721 and the stay 711 is fastened to the hanging tool. On the other hand, the stay 712 is formed so as to cover an actuator 92 (hereinafter referred to as a motor in this embodiment) fixed to the top plate portion 721.

  The motor 92 has a drive shaft 92 </ b> S protruding through the notch of the stay 712. An arm plate 931 is attached to the drive shaft 92S. Further, a link rod 932 is connected to the arm plate 931.

In addition, the upper end portion of the rotation shaft 933 protrudes from the top plate portion 721. A link plate 935 is fixed to the rotation shaft 933. The wire 91 described above is connected to one end of the link plate 935. The link rod 932 described above is connected to the other end of the link plate 935.

  With such a structure, when the drive shaft 92 </ b> S of the motor 92 rotates, the link plate 935 is rotated via the arm plate 931 and the link rod 932. Then, the rotation of the rotation shaft 933 causes the valve plate 934 to move. The wire 91 is pushed and pulled according to the rotation of the link plate 935.

  The left diverter 62Lb includes a support plate 81 and a cover member 82. The support plate 81 constitutes the left side surface of the left branch part 62Lb. Further, the cover member 82 constitutes the upper and lower surfaces and the right side surface of the left diversion portion 62Lb so as to sandwich the support plate 81 from the inside.

  The cover member 82 includes a top plate portion 821, a bottom plate portion 822, and an inclined plate portion 823. The top plate portion 821 and the bottom plate portion 822 are both provided horizontally. The inclined plate portion 823 connects the inner sides of the top plate portion 821 and the bottom plate portion 822, and is inclined obliquely downward to the left. The inclined plate portion 823 is provided with an air outlet 32d.

  More specifically, the attachment portion formed by bending the left edge portion of the top plate portion 821 upward is fastened to the upper edge portion of the support plate 81 by a bolt B3. Further, the attachment portion formed by bending the lower edge portion of the support plate 81 outward is fastened to the left edge portion of the bottom plate portion 822 by a bolt B4. In this way, the cylindrical left branch part 62Lb is assembled.

  With such a structure, the left diverter 62Lb can be disassembled simply by removing the bolts B3 and B4. As a result, the left branch part 62Lb can be easily removed from the rear bent pipe part 62La and the front bent pipe part 62Lc constituting the left air duct 62L. On the contrary, the left diversion part 62Lb can be assembled only by attaching each bolt B3 * B4. As a result, the left branch part 62Lb can be easily attached to the rear bent pipe part 62La and the front bent pipe part 62Lc constituting the left air duct 62L.

  A rotation shaft 943 is supported on the left diversion portion 62Lb by a top plate portion 821 and a bottom plate portion 822. A valve plate 944 is attached to the rotation shaft 943. In addition, the upper end portion of the rotation shaft 943 protrudes from the top plate portion 821. A link plate 945 is fixed to the rotation shaft 943. Further, an arm rod 946 is connected to the link plate 945. The wire 91 described above is connected to one end of the arm rod 946.

  With such a structure, when the wire 91 is pushed and pulled, the link plate 945 is rotated. The valve plate 944 is moved by the rotation of the rotation shaft 943.

  As described above, in the present tractor 1, the valve plate 934 of the right diversion part 62Rb and the valve plate 944 of the left diversion part 62Lb are interlocked. More specifically, the valve plate 934 that is directly movable by the motor 92 operates as a drive side member with respect to the valve plate 944. On the other hand, the valve plate 944 that is indirectly movable by the wire 91 operates as a driven member with respect to the valve plate 934.

  Thus, in the tractor 1, the link plate 935, the wire 91, the arm rod 946, and the link plate 945 constitute the interlocking mechanism 95. In addition to the link mechanism 95, the flow path switching device 96 is configured by the motor 92, the arm plate 931, the link rod 932, the rotation shaft 933, the valve plate 934, the rotation shaft 943, and the valve plate 944.

  As another embodiment, a motor 92 is provided for each of the valve plates 934 and 944. By synchronizing the motors 92, one valve plate 934 (944) and the other valve plate 944 (934) are interlocked. Also good. Alternatively, the valve plates 934 and 944 may be mechanically connected without the motor 92 and interlocked by manual operation. That is, the valve plate 934 and the valve plate 944 may be interlocked, and the configuration is not limited.

  Below, the flow path in the right branch part 62Rb and the flow path in the left branch part 62Lb will be described, and the operation mode of the above-described flow path switching device 96 will be described.

  The flow path in the right branch portion 62Rb includes a main flow path Fm that sends the adjustment air directly from the rear to the front, and a branch flow path Fb that branches from the main flow path Fm to the left. The main flow path Fm includes a space surrounded by the support plate 71 and the right half of the top plate portion 721 and the bottom plate portion 722 of the cover member 72. Further, the branch flow path Fb is configured by a space surrounded by a bag-like portion on the left half of the cover member 72.

  Further, the rotation shaft 933 is disposed in the vicinity of the left surface wall 62Rw of the front bent tube portion 62Rc, and the clearance between the rotation shaft 933 and the left surface wall 62Rw is designed to be small. Therefore, the adjustment air in the main flow path Fm is prevented from entering the branch flow path Fb. Conversely, the adjustment air in the branch flow path Fb is prevented from entering the main flow path Fm.

  Similarly, the flow path in the left branch portion 62Lb includes a main flow path Fm that sends the adjusted air directly from the rear to the front and a branch flow path Fb that branches rightward from the main flow path Fm. The main flow path Fm is configured by a space surrounded by the support plate 81 and the left half of the top plate portion 821 and the bottom plate portion 822 of the cover member 82. Further, the branch flow path Fb is configured by a space surrounded by a bag-like portion in the right half of the cover member 82.

  Further, the rotation shaft 943 is disposed in the vicinity of the right side wall 62Lw of the front bent tube portion 62Lc, and the clearance between the rotation shaft 943 and the right side wall 62Lw is designed to be small. Therefore, the adjustment air in the main flow path Fm is prevented from entering the branch flow path Fb. Conversely, the adjustment air in the branch flow path Fb is prevented from entering the main flow path Fm.

  In such a configuration, when the drive shaft 92S of the motor 92 rotates, the arm plate 931 rotates from the position Ra to the position Rb in the direction of the arrow R1. Then, when the link rod 932 is pulled rearward, the link plate 935 rotates from the position Rc to the position Rd in the direction of the arrow R2. Then, since the rotation shaft 933 also rotates together with the link plate 935, the valve plate 934 attached to the rotation shaft 933 moves. That is, the valve plate 934 rotates from the position Re to the position Rf in the direction of the arrow R3. When the valve plate 934 is at the position Re, the main flow path Fm is opened and the branch flow path Fb is closed. When the valve plate 934 is at the position Rf, the main flow path Fm is closed and the branch flow path Fb is opened.

  As a result, the adjustment air that has passed through the right branch portion 62Rb toward the front bent pipe portion 62Rc changes direction along the valve plate 934 and flows into the branch flow path Fb (see arrow Fx). And adjustment air blows off into the cabin 2 only from the blower outlet 32d.

  At the same time, the link plate 935 pushes the wire 91 forward. Then, the link 91 is rotated from the position Rg to the position Rh in the direction of the arrow R4 by pushing the wire 91 backward in the left diversion portion 62Lb. Then, since the rotation shaft 943 also rotates together with the link plate 945, the valve plate 944 attached to the rotation shaft 943 moves. That is, the valve plate 944 rotates from the position Ri to the position Rj in the direction of the arrow R5. When the valve plate 944 is at the position Ri, the main flow path Fm is opened and the branch flow path Fb is closed. When the valve plate 934 is at the position Rj, the main flow path Fm is closed and the branch flow path Fb is opened.

  As a result, the adjustment air that has passed through the left branch portion 62Lb and headed toward the front bent pipe portion 62Lc changes direction along the valve plate 944 and flows into the branch flow path Fb (see arrow Fy). And adjustment air blows off into the cabin 2 only from the blower outlet 32d.

  In order for the adjustment air to be blown into the cabin 2 only from the outlet 32c, the valve plate 934 may be set to the position Re and the valve plate 944 may be set to the position Ri. That is, the valve plates 934 and 944 may be moved in the reverse direction by rotating the drive shaft 92S of the motor 92 in the reverse direction. Thereby, since adjustment air goes to front bending pipe part 62Rc, it will blow in into cabin 2 only from blower outlet 32c.

  Furthermore, in order for the adjustment air to be blown into the cabin 2 from both the outlet 32c and the outlet 32d, the valve plate 934 may be set to an arbitrary position Rm and the valve plate 944 may be set to an arbitrary position Rn. That is, the drive shaft 92S of the motor 92 may be rotated to a predetermined phase to stop the valve plates 934 and 944 at an arbitrary angle. Thereby, the adjustment air is blown out into the cabin 2 from both the blowout port 32c and the blowout port 32d. In addition, by adjusting the angle of each valve plate 934 and 944, the air volume blown from the blower outlet 32c and the air volume blown from the blower outlet 32d can be changed.

  As described above, by moving the valve plates 934 and 944 using the motor 92 as a power source, the air outlets 32c and 32d from which the adjustment air is blown can be changed. Moreover, the air volume which blows off from each blower outlet 32c * 32d can also be changed.

  Thereby, it becomes possible to respond quickly to the cloudiness of the windshield 51 and the like. Furthermore, the comfort of the cabin 2 can be improved. In particular, the adjustment air can be blown out only from the desired air outlets 32c and 32d, or the blow-off of the adjustment air can be completely stopped, so that the operation of the fins 32cf and 32df becomes unnecessary, and the operator's work load can be greatly reduced. Further, since the valve plates 934 and 944 are moved by the single motor 92, the number of parts can be reduced, and the cost can be reduced and the cabin 2 can be reduced in size and weight.

  As described above, the right diverter 62Rb and the left diverter 62Lb are detachable from the middle of the air ducts 62R and 62L. Since the right diverter 62Rb includes a valve plate 934 that is a driving member, the valve plate 934 and the like can be attached to and detached from the right air duct 62R together with the right diverter 62Rb. Moreover, since the left diversion part 62Lb is provided with the valve plate 944 etc. which are driven members, the valve plate 944 etc. can be attached or detached together with the left diversion part 62Lb from the left air duct 62L.

  As a result, repair and replacement are facilitated, and maintenance is improved. Further, the airflow ducts 62 having various specifications can be realized by exchanging them with the diversion portions (the right diversion portion 62Rb and the left diversion portion 62Lb) having different structures. As a result, the versatility of the air conditioning system can be enhanced.

  Further, since such a structure is provided between the outer panel 31 and the inner panel 32, it is easily accessible when the outer panel 31 is removed. Since the driving force of the motor 92 is transmitted on one virtual plane Ps (the main components are arranged on the plane, the power is designed to be transmitted in a substantially two-dimensional space: FIG. See), it is easy to grasp the structure.

  This further facilitates repair / replacement and improves maintainability. Further, since the power transmission efficiency is increased, it is possible to reduce the size of the motor 92 and the like. As a result, the degree of design freedom can be increased.

  Further, as described above, the front wall 62Cw of the long tube portion 62Ca is provided with a protrusion 62Cp having a V-shaped cross section that protrudes rearward. The protrusion 62Cp is disposed so as to face the flow direction of the adjustment air that has flowed into the long pipe portion 62Ca.

  Accordingly, the adjusted air is branched and reliably distributed to each air duct (the right air duct 62R and the left air duct 62L).

  Next, a structure related to the skylight (hereinafter referred to as sunroof) 3S will be described.

  The subsequent description will be made with reference to FIGS.

  The sunroof 3S is fitted into the opening 31a of the outer panel 31. The sunroof 3S is configured by a transparent or translucent glass plate. The sunroof 3S is openable and closable on the rear end side with the front end side as a fulcrum (see arrow A).

  In the tractor 1, a sun visor 36 is provided in front of the sunroof 3S. The sun visor 36 is used to protect the eyes of the operator from direct sunlight and to ensure the visibility of the operator. The sun visor 36 is rotatable at the rear end with the front end as a fulcrum (see arrow B).

  Further, in the tractor 1, a light shielding member 37 is provided behind the sunroof 3S. The light shielding member (hereinafter referred to as a roll curtain) 37 is wound and housed on one side of the sunroof 3S. The roll curtain 37 is used to protect the operator from direct sunlight by covering the sunroof 3S. Note that the roll curtain 37 is rotated by being pulled by the operator so that the fabric can be pulled out (see arrow C).

  Below, the effect which provided the sunroof 3S and provided the roll curtain 37 which covers this sunroof 3S is demonstrated.

  According to the cabin 2 of the tractor 1, sunlight can be taken from the sunroof 3S, so that comfort in the cabin 2 can be improved. Further, since the sunroof 3S can be opened and closed, the air in the cabin 2 can be replaced. And since the roll curtain 37 which can pull out cloth | dough freely is provided, it is also possible to protect an operator from direct sunlight.

  Further, the cabin 2 of the tractor 1 is provided with an opening 32b in the inner panel 32 so that a part of the soundproof material 35 can be seen. That is, the soundproof material 35 is exposed above the operator's head. For this reason, the texture is different only in that portion, which contributes to improving the design of the cabin 2. Further, the structure in which the soundproof material 35 is exposed near the operator's head can weaken the reflection of noise around the head. As a result, the comfort in the cabin 2 can be improved.

  This point will be described in more detail. In the present tractor 1, the air conditioning unit 61 is disposed on the rear end side of the roof 3. The adjusted air sent from the air conditioning unit 61 is guided by the right air duct 62R and the left air duct 62L. By adopting such a structure, the soundproofing material 35 can be disposed between the sunroof 3S and the air conditioning unit 61 and between the right air duct 62R and the left air duct 62L. Since this position is above the operator's head, the soundproof material 35 is partially exposed to weaken the reflection of noise.

  Next, the structure regarding the windshield 51 is demonstrated.

  FIG. 17 shows a pasting margin M of the windshield 51. In the figure, the vertical direction and the horizontal direction of the tractor 1 are shown.

  The windshield 51 is constituted by a single glass plate that covers from the lower end to the upper end of the cabin 2 and from the left end to the right end. That is, the windshield 51 is constituted by a single glass plate that covers from the front plate 27 to the front beam 212 and from one front pillar 23 to the other front pillar 23.

  In the tractor 1, the windshield 51 is disposed outside the air cut plate 26 and overlaps the air cut plate 26. That is, the windshield 51 is overlaid on the outer surface of the air cut plate 26. In other words, the air cut plate 26 is overlaid on the inner surface of the windshield 51.

  The air cut plate 26 is a semi-elliptical structure in which legs 261 and 261 are formed on the left and right. The air cut plate 26 partitions the engine room and the cabin 2 and prevents the heat and noise of the engine 2 from being transmitted into the cabin 2.

  The air cut plate 26 is formed with a recess 26d from the lower end portion in the vertical direction to the upper portion, and in the substantially central portion in the left-right direction. And the rib 26R is provided in the lower end of the recessed part 26d in parallel with the left-right direction.

  With such a structure, the front glass 51 is attached to the rib 26 </ b> R at the lower center portion (see the pasting allowance M represented by diagonal lines). Further, the left and right portions of the lower end of the windshield 51 are pasted from the leg portions 261 and 261 to the front plate 27 (see the pasting allowance M represented by hatching). The left end and the right end of the windshield 51 are attached to the left and right front pillars 23, and the upper end of the windshield 51 is attached to the front beam 212 (refer to the pasting allowance M indicated by hatching).

  Below, the effect by having such a structure is demonstrated.

  The cabin of a conventional tractor has a front surface partitioned into a plurality of locations by a frame, and a windshield is fitted in each partition. Therefore, the frame has a problem of narrowing the field of view of the operator.

  However, according to the cabin 2 of the tractor 1, the windshield 51 is constituted by a single glass plate that covers from the lower end to the upper end and from the left end to the right end. Therefore, the operator's field of view can be secured widely. As a result, the comfort in the cabin 2 can be improved.

  Further, according to the cabin 2 of the tractor 1, since the windshield 51 is composed of a single glass plate, the number of parts can be reduced, and the cost can be reduced and the productivity can be improved. It becomes. Further, the length of the pasting allowance M can be shortened, and the number of work steps for attaching the windshield 51 can be reduced.

  In addition, according to the cabin 2 of the tractor 1, the engine room and the cabin 2 are partitioned by the windshield 51 and the air cut plate 26, so that the heat and noise of the engine 2 can be sufficiently blocked. Therefore, it is possible to reduce heat insulating materials and soundproofing materials, and it is also possible to reduce costs and improve productivity.

  Further, the rib 26R is provided in the recess 26d of the air cut plate 26 in parallel to the left-right direction, so that the strength of the cabin 2 in the left-right direction is improved.

  Next, the structure regarding the door 4 is demonstrated.

  The door 4 serves as an entrance for the operator. A rear end of the left door 4 (specifically, the door panel 42) is attached to the hinge 41. Also, the rear end of the right door 4 (specifically, the door panel 42) is attached to the hinge 41. The left and right doors 4 (specifically, the door panel 42) rotate around the rotation axis of the hinge 41. That is, the left and right doors 4 adopt a door structure that opens forward. The detailed structure of the door 4 will be described later.

  Hereinafter, the detailed structure of the door 4 will be described. Here, the left door 4 will be described as an example.

  FIG. 18 shows the outside of the door 4. FIG. 19 shows the inside of the door 4. In the figure, the front-rear direction and the vertical direction of the tractor 1 are shown.

  The door 4 mainly includes a hinge 41, a door panel 42, and a door lock module 43.

  The hinge 41 rotatably supports the door panel 42. The base end side of the hinge 41 is attached to the rear pillar 24. Moreover, the door panel 42 is fixed to the moving end side. Specifically, the door panel 42 is fixed while being sandwiched between the moving end side of the hinge 41 and the plate 41P fastened to the moving end side. Thus, the hinge 41 rotatably supports the door panel 42.

  The door panel 42 constitutes the side surface of the cabin 2. The door panel 42 is formed such that its front edge follows the shape of the front pillar 23. Further, the rear edge is formed so as to follow the shape of the rear pillar 24. Therefore, the door panel 42 is fitted between the front pillar 23 and the rear pillar 24 and constitutes the side surface of the cabin 2. In the tractor 1, the door panel 42 is composed of a single side glass 53.

  The door lock module 43 constitutes a lock release mechanism that allows rotation in addition to a lock mechanism that restricts rotation of the door panel 42. The door lock module 43 is designed to release the lock by operating the outdoor lever 431. In addition, the lock is designed to be released by operating the indoor lever 438. Thus, the door lock module 43 constitutes a lock release mechanism that allows rotation by an operator's operation.

  Hereinafter, the detailed structure of the door lock module 43 will be described. However, portions that are not related to the present invention are omitted.

  20 and 21 show an operation mode of the door lock module 43. FIG. In the figure, the front-rear direction, the up-down direction, and the left-right direction of the tractor 1 are represented. In addition, the arrow shown in the drawing represents the operation direction of each component constituting the door lock module 43.

  The door lock module 43 is composed of many components in addition to the outdoor lever 431 and the indoor lever 438.

  The outdoor lever 431 is provided outside the door panel 42. The outdoor lever 431 is attached so that the moving end side 431d is upward with respect to the base end side 431s. The door lock module 43 is designed to release the lock when the moving end side 431d of the outdoor lever 431 rotates in a direction away from the door panel 42 around a rotation axis (not shown).

  If it demonstrates concretely, the outdoor lever 431 will be rotatable centering on the rotating shaft provided in base end side 431s. Therefore, the operator can grasp the outdoor lever 431 and rotate the moving end side 431d in a direction away from the door panel 42 (operation to pull out the moving end side 431d: see arrow A). Then, the plate 432 rotates with the rotation of the outdoor lever 431 and pushes up the rod 433 attached to the plate 432 upward. When the control arm 434 is rotated upward, the link arm 435 is also rotated accordingly. Finally, the latch 436 is also rotated by the rotation of the link arm 435, and the latch 436 is detached from the striker 437.

  As described above, the door lock module 43 of the tractor 1 includes the outdoor lever 431, and the lock is released when the moving end side 431 d of the outdoor lever 431 rotates in a direction away from the door panel 42. Thereby, since the operation | movement which opens the door 4 becomes easy, operativity can be improved.

  In addition, in the present tractor 1, an outdoor lever 431 is disposed above the sub-step 29 (see FIG. 18). The outdoor lever 431 is attached so that the moving end side 431d is located above the base end side 431s. Thereby, when the vehicle height of the tractor 1 is high, the operator can hold the outdoor lever 431 and pull up the body. Further, since the operator can grasp the outdoor lever 431 from below and pull down the moving end side 431d to release the lock, the operation of opening the door 4 becomes easy.

  The indoor lever 438 is provided inside the door panel 42. The indoor lever 438 is attached so that the moving end side 438d is located behind the base end side 438s. The door lock module 43 is designed to release the lock when the moving end side 438d of the indoor lever 438 rotates in a direction away from the door panel 42 about the rotation shaft 438A.

  More specifically, the indoor lever 438 is rotatable about a rotation shaft provided on the base end side 438s. Therefore, the operator can put the indoor lever 438 on the finger and turn the moving end side 438d away from the door panel 42 (operation to pull out the moving end side 438d: see arrow B). Then, as the indoor lever 438 rotates, the rod 439 is pulled rearward to rotate the control arm 434 upward. When the control arm 434 is rotated upward, the link arm 435 is also rotated accordingly. Finally, the latch 436 is also rotated by the rotation of the link arm 435, and the latch 436 is detached from the striker 437.

  As described above, the door lock module 43 of the tractor 1 includes the indoor lever 438, and the lock is released when the moving end side 438 d of the indoor lever 438 rotates away from the door panel 42. Thereby, since the operation | movement which opens the door 4 becomes easy, operativity can be improved.

  In addition, in the present tractor 1, an indoor lever 438 is disposed in front of the driver seat 19 (see FIG. 19). And the indoor lever is attached so that the moving end side may become back with respect to the base end side. As a result, in the door structure that opens forward, the operator can easily unlock the door 4 by placing a finger on the indoor lever 438 from behind and causing the moving end 431d to be unlocked. The operator can open the door 4 by pushing the indoor lever 438.

  Next, other characteristic points of the door structure described above will be described.

  The door structure includes a side frame 44 and a frame cover 45.

  The side frame 44 is connected to the door lock module 43. More specifically, the side frame 44 has one end connected to the door lock module 43 and the other end connected to the hinge 41. Thus, the side frame 44 is disposed so as to cross the door panel 42 (see FIGS. 18 and 19). The side frame 44 is formed by bending a carbon steel pipe.

  The frame cover 45 covers the side frame 44. More specifically, the frame cover 45 is formed along the side frame 44 and covers the periphery of the side frame 44. Thus, the frame cover 45 is disposed integrally with the side frame 44. The frame cover 45 is formed by solidifying a resin material. The frame cover 45 is provided with a lever guard. The lever guard is a recess 45 d for enclosing the indoor lever 438.

  As described above, the door structure of the tractor 1 includes the side frame 44 connected to the door lock module 43. A frame cover 45 that covers the side frames 44 is also provided. The frame cover 45 has a recess 45 d for enclosing the indoor lever 438. Thereby, since exposure of a metal component decreases, a high-class feeling can be improved. In addition, since the indoor lever 438 is enclosed by the frame cover, an erroneous operation of the indoor lever 438 can be prevented.

  In addition, in the tractor 1, a grip 45g is formed on the frame cover 45 (see FIGS. 18 and 19). The grip 45g gradually decreases in height from at least the vicinity of the driver seat 19 to the door lock module 43 (see arrow S in FIGS. 18 and 19). As a result, the frame cover 45 follows the operator's line of sight (a slightly downward line of sight when the operator is sitting on the driver's seat 19 and maneuvering: see arrow E in FIGS. 18 and 19) and overlaps the door lock module 43. Therefore, a wide field of view can be secured.
