[0010] An exemplary embodiment will now be described in detail with reference to the drawings. FIG. 1 is a left side view of a utility vehicle 100. The utility vehicle 100 is capable of traveling off-road. The utility vehicle 100 is an example of an off-road vehicle. Hereinafter, the utility vehicle 100 will also be simply referred to as "vehicle 100."

[0011] In this disclosure, each configuration of the vehicle 100 will be described using the directions of the vehicle 100. Specifically, "front" means the front of the vehicle 100 in the longitudinal direction, and "rear" means the rear of the vehicle 100 in the longitudinal direction. "Left" means the left when facing the front of the vehicle 100, and "right" means the right when facing the front of the vehicle 100. "Vehicle width direction" means the width direction of the vehicle 100, or in other words, the left-right direction of the vehicle 100, and is sometimes referred to as the "left-right direction." "Inside in the vehicle width direction" means the cabin side in the vehicle width direction, and "outside in the vehicle width direction" means the outside side of the vehicle in the vehicle width direction.

[0012] The vehicle 100 comprises a body frame 1, left and right front wheels 3 that support the front of the body frame 1, and left and right rear wheels 4 that support the rear of the body frame 1. In other words, the vehicle 100 is a four-wheeled automobile. The space between the left and right front wheels 3 is covered from above by a hood 5. Left and right seats 6 that are supported by the body frame 1 are arranged behind the hood 5.

[0013] The seat 6 has a seat portion 61 and a back portion 62. The seat portion 61 supports the buttocks of the occupant. The back portion 62 supports the back of the occupant. A seat belt 15 is attached to the vehicle body frame 1. The seat belt 15 restrains the occupant to the seat 6. The seat belt 15 is, for example, a three-point seat belt. The seat belt 15 has a belt portion and an upper attachment portion through which the belt portion passes and which is attached to the vehicle body frame. The upper attachment portion adjusts the position of the belt portion resting on the occupant's shoulders.

[0014] The body frame 1 includes a plurality of hollow pipes which are connected to one another to form a frame. The body frame 1 has a cabin frame 1a which defines a vehicle interior 7 in which seats 6 are arranged. Doors for boarding and alighting are open on both the left and right sides of the vehicle interior 7 and are opened and closed by doors 8. A dashboard 9 is disposed in front of the seats 6 inside the vehicle interior 7. A handle 10 is attached to the dashboard 9. A luggage rack 2 is disposed behind the cabin frame 1a. The luggage rack 2 includes a concave loading space which opens upward.

[0015] The vehicle 100 has an engine 11, a continuously variable transmission 12, a fan 13, and a duct assembly 20. The engine 11, the continuously variable transmission 12, and the fan 13 are arranged behind the seat 6 and below the cargo bed 2. The vehicle 100 may also have a generator that generates electricity using the power of the engine 11, a battery that stores the electricity generated by the generator, and the like.

[0016] The engine 11 generates power. The engine 11 is, for example, a reciprocating engine. The engine 11 has a casing, pistons, and a crankshaft. The pistons and crankshaft are disposed within the casing. The crankshaft is connected to the pistons and converts the reciprocating motion of the pistons into rotational motion.

[0017] The continuously variable transmission 12 changes the output rotation speed of the engine 11. The continuously variable transmission 12 includes a casing, a drive pulley, a driven pulley, and a belt. The drive pulley, the driven pulley, and the belt are arranged inside the casing. The belt is wound around the drive pulley and the driven pulley.

[0018] The torque (rotational power) of the engine 11 is transmitted to the drive pulley via the input shaft. The rotation of the drive pulley is transmitted to the driven pulley via the belt. The rotation of the driven pulley is transmitted to the rear wheel 4 via the output shaft. In this way, the continuously variable transmission 12 transmits the torque of the engine 11 to the rear wheel 4. The drive pulley is configured so that the radial position around which the belt is wound can be changed. The driven pulley is configured so that the radial position around which the belt is wound can be changed. In this way, the continuously variable transmission 12 continuously changes the rotational speed of the engine 11 and transmits it to the rear wheel 4. Note that the continuously variable transmission 12 may also be configured so that the torque of the engine 11 is transmitted to the front wheel 3 and the rear wheel 4.

[0019] The fan 13 generates an airflow to cool the engine 11. The fan 13 has a casing and an impeller. The impeller is disposed within the casing. The impeller is connected to, for example, a transmission shaft. The transmission shaft is connected to the crankshaft via a gear or the like. As a result, the rotation of the crankshaft is transmitted to the transmission shaft, causing the impeller to rotate. The rotation of the impeller generates an airflow.

[0020] The duct assembly 20 is disposed behind the seat 6 and above and below the luggage compartment 2. The duct assembly 20 is connected to each of the engine 11, the continuously variable transmission 12, and the fan 13. The duct assembly 20 takes in air and exhausts air.

[0021] Fig. 2 is a perspective view showing the duct assembly 20 as seen from the rear. Fig. 3 is a schematic rear view showing the duct assembly 20 as seen from the rear. In Fig. 2, the engine 11 is omitted. In Fig. 3, the upper end 6a of the seat 6 is indicated by a two-dot chain line, and the seat belt 15 is omitted. In Fig. 3, the flow of air inside the duct assembly 20 is indicated by arrows.

[0022] The duct assembly 20 has an engine intake duct 21 , a CVT intake duct 22 , a fan intake duct 23 , a CVT exhaust duct 32 , and a fan exhaust duct 33 .

[0023] The engine intake duct 21, the CVT intake duct 22, the fan intake duct 23, the CVT exhaust duct 32, and the fan exhaust duct 33 are arranged in the vehicle width direction. Specifically, the engine intake duct 21, the CVT exhaust duct 32, the CVT intake duct 22, the fan exhaust duct 33, and the fan intake duct 23 are arranged in this order from left to right in the vehicle width direction.

[0024] The engine 11, the continuously variable transmission 12, and the fan 13 are arranged at approximately the same height. The engine 11, the continuously variable transmission 12, and the fan 13 are arranged in the vehicle width direction. Specifically, the continuously variable transmission 12, the engine 11, and the fan 13 are arranged in this order from left to right in the vehicle width direction.

[0025] The engine intake duct 21 is connected to the engine 11 and sends outside air to the engine 11. When the engine 11 is driven, negative pressure is created inside the engine intake duct 21. As a result, outside air is drawn into the engine 11 through the engine intake duct 21. The air drawn into the engine 11 is then combusted in the combustion chamber. The exhaust gas combusted in the combustion chamber is then discharged to the outside through an exhaust duct (not shown).

[0026] CVT intake duct 22 is connected to continuously variable transmission 12 and sends outside air to continuously variable transmission 12. CVT exhaust duct 32 is connected to continuously variable transmission 12 and exhausts internal air from continuously variable transmission 12. Negative pressure is created inside CVT intake duct 22 when continuously variable transmission 12 is driven. As a result, outside air is drawn into the interior of continuously variable transmission 12 from CVT intake duct 22. The air drawn into the interior of continuously variable transmission 12 then cools the interior of continuously variable transmission 12. The air inside continuously variable transmission 12 is then exhausted to the outside from CVT exhaust duct 32.

[0027] The fan intake duct 23 is connected to the fan 13 and sends outside air to the fan 13. The fan exhaust duct 33 is connected to the fan 13 and exhausts inside air from the fan 13. When the fan 13 is driven, negative pressure is created inside the fan intake duct 23. As a result, outside air is drawn into the inside of the fan 13 from the fan intake duct 23. The air drawn into the inside of the fan 13 is then exhausted to the outside from the fan exhaust duct 33. The air exhausted from the fan exhaust duct 33 is blown onto the engine 11 to cool the engine 11 from the outside.

[0028] The engine intake duct 21 extends while curving downward from the upstream to downstream of the air flow. The CVT intake duct 22 extends while curving downward from the upstream to downstream of the air flow. The fan intake duct 23 extends while curving downward from the upstream to downstream of the air flow.

[0029] The intake port 210 of the engine intake duct 21 is located at a higher position than the engine 11. The intake port 220 of the CVT intake duct 22 is located at a higher position than the continuously variable transmission 12. The intake port 230 of the fan intake duct 23 is located at a higher position than the fan 13.

[0030] At least one of the three air intakes 210, 220, 230 is arranged at a position higher than the upper end 6a of the seat 6. In this embodiment, each of the three air intakes 210, 220, 230 is arranged at a position higher than the upper end 6a of the left and right seats 6. Specifically, each of the three air intakes 210, 220, 230 is higher than the upper end 6a of the back 62 of the seat 6. The three air intakes 210, 220, 230 are located at approximately the same height. Note that each of the three air intakes 210, 220, 230 may be arranged at a position higher than the upper end 6a of either the left or right seat 6.

[0031] Each of the three air intakes 210, 220, and 230 is disposed at a position higher than the upper end of the loading platform 2. Specifically, each of the three air intakes 210, 220, and 230 is disposed at a position higher than the opening end that opens upward of the loading platform 2.

[0032] Each of the three air intakes 210, 220, and 230 is disposed at a position higher than the upper end of the seat belt 15. Specifically, each of the three air intakes 210, 220, and 230 is disposed at a position higher than the upper attachment portion of the seat belt 15.

[0033] Each of the three air intakes 210, 220, and 230 opens rearward. The three air intakes 210, 220, and 230 are arranged at intervals in the vehicle width direction. The three air intakes 210, 220, and 230 are arranged in order from left to right in the vehicle width direction.

[0034] CVT exhaust duct 32 extends upward from continuously variable transmission 12 and then extends downward as it moves from upstream to downstream in the air flow. Fan exhaust duct 33 extends upward from fan 13 and then extends downward as it moves from upstream to downstream in the air flow. In this way, CVT exhaust duct 32 and fan exhaust duct 33 each extend while being folded back and curved in a U-shape.

[0035] CVT exhaust duct 32 has a bent portion 35 midway along its path that extends upward and then downward as it moves from upstream to downstream. Fan exhaust duct 33 has a bent portion 35 midway along its path that extends upward and then downward as it moves from upstream to downstream. An upper end 35a of bent portion 35 is positioned higher than a seating surface 61a of a seat portion 61 of seat 6.

[0036] The exhaust port 320 of the CVT exhaust duct 32 is located at a higher position than the continuously variable transmission 12. The exhaust port 330 of the fan exhaust duct 33 is located at a higher position than the fan 13. The intake port 230 of the fan intake duct 23 is located at a higher position than the exhaust port 330 of the fan exhaust duct 33.

[0037] The two exhaust ports 320, 330 are located above the engine 11. The two exhaust ports 320, 330 face the engine 11. As a result, the air discharged from each of the two exhaust ports 320, 330 is blown against the casing of the engine 11 to cool the engine 11.

[0038] 4 is a perspective view showing the periphery of exhaust port 330 of fan exhaust duct 32 as viewed from the front. Fan exhaust duct 33 has through-hole 36 for discharging air midway along the path of fan exhaust duct 33. Through-hole 36 is located near exhaust port 330.

[0039] The vehicle 100 further includes a voltage regulator 16. The voltage regulator 16 is an example of a component to be cooled in the present disclosure. The voltage regulator 16 is a device that adjusts and rectifies the voltage generated by the generator and supplies the voltage to the battery.

[0040] The through-hole 36 is disposed at a position facing the voltage regulator 16. Specifically, the through-hole 36 is disposed above the voltage regulator 16. As a result, the air discharged from the through-hole 36 is blown onto the voltage regulator 16 to cool it.

[0041] The component to be cooled may be a component other than the voltage regulator, such as an electronic component or a heat-generating component such as the engine 11.

[0042] 3, the CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 are integrated. Specifically, the CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 are integrally molded. The fan exhaust duct 33 is disposed between the CVT intake duct 22 and the fan intake duct 23. Hereinafter, the integrated CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 will also be referred to as a first duct group 20a.

[0043] The engine intake duct 21 and the CVT exhaust duct 32 are integrated. Specifically, the engine intake duct 21 and the CVT exhaust duct 32 are integrally molded. Hereinafter, the integrated engine intake duct 21 and CVT exhaust duct 32 will also be referred to as a second duct group 20b.

[0044] The CVT intake duct 22 and the CVT exhaust duct 32 are fastened together. That is, the first duct group 20a and the second duct group 20b are fastened together. Specifically, the CVT intake duct 22 and the CVT exhaust duct 32 are fixed to each other by two fastening portions 40. The two fastening portions 40 are a first fastening portion 40 and a second fastening portion 40.

[0045] The first co-tightening portion 40 is located on the lower side, and the second co-tightening portion 40 is located on the upper side. Specifically, the first co-tightening portion 40 is located near the exhaust port 320 of the CVT exhaust duct 32. The second co-tightening portion 40 is located near the upper end 35a of the bent portion 35 of the CVT exhaust duct 32.

[0046] The co-tightening portion 40 has a first mounting plate 41, a second mounting plate 42, and a fastening member 43. The first mounting plate 41 is fixed to the CVT intake duct 22. The second mounting plate 42 is fixed to the CVT exhaust duct 32. The first mounting plate 41 and the second mounting plate 42 are overlapped, and the fastening member 43 passes through the overlapping portion of the first mounting plate 41 and the second mounting plate 42 to fasten them. The fastening member 43 is, for example, a bolt and nut.

[0047] The CVT intake duct 22 and the fan exhaust duct 33 may be further fastened together. Specifically, the CVT intake duct 22 and the fan exhaust duct 33 are fixed to each other by a fastening portion 40. In more detail, the fastening portion 40 has a first mounting plate fixed to the CVT intake duct 22, a second mounting plate fixed to the fan exhaust duct 33, and a fastening member that fastens the first mounting plate and the second mounting plate together.

[0048] 5 is a front view showing the engine intake duct 21, the CVT intake duct 22, and the fan intake duct 23. FIG 6 is a cross-sectional view taken along line VI-VI in FIG 5.

[0049] The vehicle 100 further includes a nut 17. The nut 17 is embedded in the outer surface 50a midway through the engine intake duct 21, the CVT intake duct 22, and the fan intake duct 23.

[0050] Specifically, CVT intake duct 22 has a bulge 50 in an upper and front region of the outer surface of CVT intake duct 22. Nut 17 is embedded in bulge 50. Nut 17 is molded integrally with CVT intake duct 22 by, for example, casting.

[0051] The nut 17 is flush with the outer surface 50a of the bulge 50. The outer surface 50a of the bulge 50 is flat. The surface of the nut 17 is flat. The outer surface 50a of the bulge 50 and the surface of the nut 17 are flush with each other.

[0052] The bulging portion 50 of the engine intake duct 21 and the bulging portion 50 of the fan intake duct 23 have the same configuration as the bulging portion 50 of the CVT intake duct 22. That is, in the engine intake duct 21, the nut 17 is flush with the outer surface 50a of the bulging portion 50. In the fan intake duct 23, the nut 17 is flush with the outer surface 50a of the bulging portion 50.

[0053] 7 is a cross-sectional view showing a state in which the CVT intake duct 22 is attached to the cabin frame 1a of the vehicle body frame 1. The CVT intake duct 22 is attached to the cabin frame 1a via a bracket 18.

[0054] Specifically, bracket 18 is fixed to cabin frame 1a. With outer surface 50a of bulging portion 50 of CVT intake duct 22 in contact with bracket 18, bolt 19 passes through bracket 18 and is fastened to nut 17 embedded in bulging portion 50. In this way, CVT intake duct 22 is attached to bracket 18 by fastening bolt 19. At this time, CVT intake duct 22 is attached to bracket 18 with outer surface 50a of bulging portion 50 and the surface of nut 17 in contact with bracket 18.

[0055] The engine intake duct 21 and the fan intake duct 23 are attached to the cabin frame 1a in the same manner as the CVT intake duct 22. That is, the engine intake duct 21 and the fan intake duct 23 are attached to the cabin frame 1a via brackets 18.

[0056] 8 is a perspective view showing the area around intake port 220 of CVT intake duct 22 as seen from behind. The open end of CVT intake duct 22 on the intake port 220 side has filter mounting surface 25. A filter (not shown) can be attached to filter mounting surface 25. The filter is attached to filter mounting surface 25 with, for example, an adhesive sheet. The filter prevents foreign matter larger than the mesh of the filter from entering.

[0057] The filter mounting surface 25 extends in the circumferential direction of the open end. The filter mounting surface 25 faces rearward. An annular wall portion 26 is provided on the outer peripheral edge of the filter mounting surface 25. The wall portion 26 rises from the filter mounting surface 25 and protrudes rearward. When the filter is mounted on the filter mounting surface 25, the wall portion 26 prevents the filter from protruding outward from the outer periphery of the filter mounting surface 25.

[0058] In this example, a lattice member 27 including a plurality of holes is attached to the air intake port 220. The lattice member 27 prevents the intrusion of foreign objects larger than the holes in the lattice member 27. The holes in the lattice member 27 are larger than the mesh size of the filter. Note that the lattice member 27 may be omitted.

[0059] Similarly, the open end of engine intake duct 21 on the intake port 210 side and the open end of fan intake duct 23 on the intake port 230 side have filter mounting surfaces 25. This allows a filter to be mounted on filter mounting surfaces 25.

[0060] In the vehicle 100 described above, at least one of the intake port 210 of the engine intake duct 21, the intake port 220 of the CVT intake duct 22, and the intake port 230 of the fan intake duct 23 is positioned higher than the upper end 6a of the seat 6. This reduces the possibility of foreign matter being sucked into at least one of the intake ports.

[0061] Specifically, when the vehicle 100 travels through a marsh or swamp, foreign matter contained in the marsh or swamp is kicked up by the wheels and scattered. The foreign matter is, for example, water, mud, sand, stones, and other objects contained in the marsh or swamp. However, the scattered foreign matter is unlikely to reach the face of the occupant. Therefore, by locating at least one air intake at a position higher than the upper end 6a of the seat 6, which corresponds to the position of the occupant's face, it is possible to reduce the inhalation of foreign matter through the at least one air intake.

[0062] Furthermore, since the intake port 210 of the engine intake duct 21 is positioned higher than the upper end 6a of the seat 6, it is possible to reduce the amount of foreign matter being sucked in through the intake port 210 of the engine intake duct 21. This reduces the amount of foreign matter entering the engine 11, and reduces the deterioration of the performance of the engine 11.

[0063] Furthermore, since intake port 220 of CVT intake duct 22 is located at a position higher than upper end 6a of seat 6, it is possible to reduce the amount of foreign matter being sucked in through intake port 220 of CVT intake duct 22. This reduces the amount of foreign matter entering continuously variable transmission 12, and reduces the degradation of performance of continuously variable transmission 12.

[0064] Furthermore, since air intake port 230 of fan air intake duct 23 is positioned higher than upper end 6a of seat 6, it is possible to reduce the amount of foreign matter being sucked in through air intake port 230 of fan air intake duct 23. This reduces the amount of foreign matter entering fan 13, and reduces the deterioration of performance of fan 13.

[0065] Furthermore, since air intake port 230 of fan intake duct 23 is positioned higher than air exhaust port 330 of fan exhaust duct 33, it is possible to reduce the amount of foreign matter being sucked in through air intake port 230 of fan intake duct 23. This reduces the amount of foreign matter entering fan 13, and reduces the deterioration of performance of fan 13.

[0066] Furthermore, since the fan exhaust duct 33 has the through-holes 36, the air discharged from the through-holes 36 can cool the components facing the through-holes 36.

[0067] Furthermore, since the through holes 36 are disposed at positions facing the components to be cooled, the air discharged from the through holes 36 can cool the components to be cooled.

[0068] Furthermore, since the component to be cooled is a voltage regulator, the voltage regulator can be cooled.

[0069] Furthermore, since the nuts 17 are embedded flush with the outer surface 50a of the CVT intake duct 22, when the bolts 19 are passed through the bracket 18 fixed to the body frame 1 and fastened to the nuts 17 to attach the CVT intake duct 22 to the bracket 18, the CVT intake duct 22 can be attached to the bracket 18 in a stable position.

[0070] More specifically, if the nut 17 protrudes from the outer surface 50a of the CVT intake duct 22, when the CVT intake duct 22 is attached to the bracket 18, the bracket 18 comes into contact with the nut 17 and moves away from the outer surface 50a of the CVT intake duct 22. This makes the attachment posture of the CVT intake duct 22 to the bracket 18 unstable. In contrast, in the present disclosure, the nut 17 is flush with the outer surface 50a of the CVT intake duct 22, so the bracket 18 comes into contact with the nut 17 and the outer surface 50a of the CVT intake duct 22, stabilizing the attachment posture of the CVT intake duct 22 to the bracket 18.

[0071] Similarly, since the nut 17 is embedded flush with the outer surface 50a of the engine intake duct 21, when the engine intake duct 21 is attached to the bracket 18, the engine intake duct 21 can be attached to the bracket 18 in a stable position.

[0072] Similarly, since the nut 17 is embedded flush with the outer surface 50a of the fan intake duct 23, when the fan intake duct 23 is attached to the bracket 18, the fan intake duct 23 can be attached to the bracket 18 in a stable position.

[0073] Furthermore, since the CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 are integrated, the CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 can be easily assembled to the vehicle 100.

[0074] Furthermore, since the engine intake duct 21 and the CVT exhaust duct 32 are integrated, the engine intake duct 21 and the CVT exhaust duct 32 can be easily assembled to the vehicle 100.

[0075] Furthermore, since the CVT intake duct 22 and the CVT exhaust duct 32 are fastened together, the integrated CVT intake duct 22, fan intake duct 23, and fan exhaust duct 33 (first duct group 20a) can be fixed to the integrated engine intake duct 21 and CVT exhaust duct 32 (second duct group 20b) with each other, thereby stabilizing the posture of all the ducts.

[0076] Furthermore, the open end of engine intake duct 21 on the intake port 210 side, the open end of CVT intake duct 22 on the intake port 220 side, and the open end of fan intake duct 23 on the intake port 230 side each have a filter mounting surface 25. This allows a filter to be mounted on filter mounting surface 25.

[0077] Furthermore, the three air intakes 210, 220, and 230 are disposed at a position higher than the upper end of the loading platform 2. This reduces the possibility of foreign objects being sucked in through the three air intakes 210, 220, and 230.

[0078] Furthermore, the three air intakes 210, 220, and 230 are disposed at a position higher than the upper end of the seat belt 15. This reduces the possibility of foreign objects being sucked in through the three air intakes 210, 220, and 230.

[0079] Furthermore, the three intake ports 210, 220, 230 open to the rear, which reduces the chance of foreign matter scattered from the front to the rear being sucked in through the three intake ports 210, 220, 230 while the vehicle 100 is traveling forward.

[0080] Furthermore, the three air intakes 210, 220, 230 are arranged at intervals in the vehicle width direction, which allows the three air intakes 210, 220, 230 to be dispersed in the vehicle width direction, thereby reducing the possibility of foreign matter being sucked in through all of the air intakes.

[0081] Furthermore, because the CVT exhaust duct 32 has a bent portion 35, even if a foreign object enters the exhaust port 320 of the CVT exhaust duct 32, the foreign object is unlikely to pass over the bent portion 35 and enter upstream. Specifically, even if the foreign object enters the exhaust port 320, it must move upward until it reaches the upper end 35a of the bent portion 35. This makes it difficult for the foreign object to reach the upper end 35a due to the influence of gravity. Therefore, it is possible to reduce the backflow of foreign object through the CVT exhaust duct 32.

[0082] Furthermore, since the upper end 35a of the bent portion 35 is positioned higher than the seating surface 61a of the seat 6, the backflow of foreign matter through the CVT exhaust duct 32 can be reduced.

[0083] Similarly, because fan exhaust duct 33 has bent portion 35, even if foreign matter enters exhaust port 330 of fan exhaust duct 33, the foreign matter is unlikely to pass bent portion 35 and enter upstream. This reduces the possibility of foreign matter flowing backward through the exhaust duct.

[0084] Furthermore, since the upper end 35a of the bent portion 35 is positioned higher than the seat surface 61a of the seat 6, the backflow of foreign matter through the fan exhaust duct 33 can be reduced.

[0085] Variation 1 Next, a vehicle (an example of an off-road vehicle) according to Modification 1 will be described mainly with reference to Figures 1, 2, and 3. Unlike vehicle 100 according to the embodiment, the vehicle according to Modification 1 does not care about the height of intake port 220 of CVT intake duct 22 and intake port 230 of fan intake duct 23. In Modification 1, the same reference numerals as those in the embodiment have the same configuration as those in the embodiment, and therefore description thereof will be omitted.

The engine intake duct 21 is connected to the engine 11 and sends outside air to the engine 11. An intake port 210 of the engine intake duct 21 is located at a position higher than an upper end 6a of the seat 6.

[0087] In the vehicle according to the first modification, the intake port 210 of the engine intake duct 21 is positioned higher than the upper end 6a of the seat 6. This reduces the possibility of foreign matter being sucked in through the intake port 210 of the engine intake duct 21. This reduces the possibility of foreign matter entering the engine 11, and reduces the deterioration of the performance of the engine 11.

Alternatively, filter mounting surface 25 may be omitted.

[0108] The techniques disclosed herein may be applied to off-road vehicles other than the utility vehicle 100.

[0109] [Aspect] The above-described embodiment is a specific example of the following aspects.

[0110] (Aspect 1) The utility vehicle 100 (off-road vehicle) is a utility vehicle 100 having a seat 6, an engine 11, a continuously variable transmission 12, and a fan 13, and is equipped with an engine intake duct 21 connected to the engine 11 and sending outside air to the engine 11, a CVT intake duct 22 connected to the continuously variable transmission 12 and sending outside air to the continuously variable transmission 12, and a fan intake duct 23 connected to the fan 13 and sending outside air to the fan 13, and at least one of the intake port 210 of the engine intake duct 21, the intake port 220 of the CVT intake duct 22, and the intake port 230 of the fan intake duct 23 is positioned at a position higher than the upper end 6a of the seat 6.

[0111] According to this configuration, at least one of the intake port 210 of the engine intake duct 21, the intake port 220 of the CVT intake duct 22, and the intake port 230 of the fan intake duct 23 is positioned higher than the upper end 6a of the seat 6. This reduces the possibility of foreign matter being sucked in through at least one of the intake ports.

[0112] (Aspect 2) The utility vehicle 100 (off-road vehicle) is a utility vehicle 100 having a seat 6 and an engine 11, and is equipped with an engine intake duct 21 connected to the engine 11 and sending outside air to the engine 11, and the intake port 210 of the engine intake duct 21 is positioned at a higher position than the upper end 6a of the seat 6.

[0113] According to this configuration, the intake port 210 of the engine intake duct 21 is positioned higher than the upper end 6a of the seat 6. This reduces the amount of foreign matter that is sucked in through the intake port 210 of the engine intake duct 21. This reduces the amount of foreign matter that gets into the engine 11, and reduces the deterioration of the performance of the engine 11.

[0114] (Aspect 3) In the utility vehicle 100 according to the first or second aspect, the intake port 210 of the engine intake duct 21 is disposed at a position higher than the upper end 6 a of the seat 6 .

[0115] With this configuration, the intake port 210 of the engine intake duct 21 is positioned higher than the upper end 6a of the seat 6, which reduces the amount of foreign matter being sucked in through the intake port 210 of the engine intake duct 21. This reduces the amount of foreign matter entering the engine 11, and reduces the deterioration of the performance of the engine 11.

[0116] (Aspect 4) In the utility vehicle 100 according to any one of the first to third aspects, the intake port 220 of the CVT intake duct 22 is disposed at a position higher than the upper end 6 a of the seat 6 .

[0117] According to this configuration, intake port 220 of CVT intake duct 22 is located at a position higher than upper end 6a of seat 6, which reduces the possibility of foreign matter being sucked in through intake port 220 of CVT intake duct 22. Therefore, it is possible to reduce the possibility of foreign matter entering continuously variable transmission 12, and to reduce the deterioration of performance of continuously variable transmission 12.

[0118] (Aspect 5) In the utility vehicle 100 according to any one of the first to fourth aspects, the intake port 230 of the fan intake duct 23 is disposed at a position higher than the upper end 6 a of the seat 6 .

[0119] With this configuration, air intake port 230 of fan air intake duct 23 is positioned higher than upper end 6a of seat 6, which reduces the amount of foreign matter being sucked in through air intake port 230 of fan air intake duct 23. This reduces the amount of foreign matter entering fan 13, and reduces the degradation of fan 13 performance.

[0120] (Aspect 6) In the utility vehicle 100 described in any one of aspects 1 to 5, a fan exhaust duct 33 is further provided which is connected to the fan 13 and discharges internal air from the fan 13, and the intake port 230 of the fan intake duct 23 is positioned at a higher position than the exhaust port 330 of the fan exhaust duct 33.

[0121] With this configuration, air intake port 230 of fan intake duct 23 is positioned higher than air exhaust port 330 of fan exhaust duct 33, which reduces the likelihood of foreign matter being sucked in through air intake port 230 of fan intake duct 23. This reduces the likelihood of foreign matter entering fan 13, and reduces any degradation in the performance of fan 13.

[0122] (Aspect 7) The utility vehicle 100 described in any one of aspects 1 to 6 further comprises a CVT exhaust duct 32 connected to the continuously variable transmission 12 and discharging internal air from the continuously variable transmission 12, and a fan exhaust duct 33 connected to the fan 13 and discharging internal air from the fan 13, and at least one of the CVT exhaust duct 32 and the fan exhaust duct 33 has a through hole 36 for discharging air midway along the path of the exhaust duct.

[0123] According to this configuration, at least one of the exhaust ducts, the CVT exhaust duct 32 and the fan exhaust duct 33, has a through hole 36, so that the air discharged from the through hole 36 can cool the components facing the through hole 36.

[0124] (Aspect 8) The utility vehicle 100 according to any one of the first to seventh aspects further includes a component to be cooled, and the through-hole 36 is disposed at a position facing the component to be cooled.

[0125] According to this configuration, the through-holes 36 are disposed at positions facing the components to be cooled, so that the air discharged from the through-holes 36 can cool the components to be cooled.

[0126] (Aspect 9) In the utility vehicle 100 according to any one of the first to eighth aspects, the component to be cooled is a voltage regulator.

[0127] According to this configuration, since the component to be cooled is the voltage regulator, it is possible to cool the voltage regulator.

[0128] (Aspect 10) The utility vehicle 100 described in any one of aspects 1 to 9 further includes a nut 17 embedded in the outer surface 50a midway through the route of at least one of the intake ducts, namely the engine intake duct 21, the CVT intake duct 22, and the fan intake duct 23, and the nut 17 is flush with the outer surface 50a.

[0129] According to this configuration, the nut 17 is embedded flush with the outer surface 50a of the intake duct, so that when the bolt 19 is passed through the bracket 18 fixed to the body frame 1 and fastened to the nut 17 to attach the intake duct to the bracket 18, the intake duct can be attached to the bracket 18 in a stable position.

[0130] (Aspect 11) In the utility vehicle 100 described in any one of aspects 1 to 10, a fan exhaust duct 33 is further provided which is connected to the fan 13 and exhausts internal air from the fan 13, and the CVT intake duct 22, the fan intake duct 23 and the fan exhaust duct 33 are integrated.

[0131] According to this configuration, the CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 are integrated, so that the CVT intake duct 22, the fan intake duct 23, and the fan exhaust duct 33 can be easily assembled to the vehicle.

[0132] (Aspect 12) The utility vehicle 100 described in any one of aspects 1 to 11 further includes a CVT exhaust duct 32 connected to the continuously variable transmission 12 and discharging internal air from the continuously variable transmission 12, and the engine intake duct 21 and the CVT exhaust duct 32 are integrated.

[0133] According to this configuration, the engine intake duct 21 and the CVT exhaust duct 32 are integrated, so that the engine intake duct 21 and the CVT exhaust duct 32 can be easily assembled to the vehicle.

[0134] (Aspect 13) The utility vehicle 100 described in any one of aspects 1 to 12 further includes a CVT exhaust duct 32 connected to the continuously variable transmission 12 and discharging internal air from the continuously variable transmission 12, the engine intake duct 21 and the CVT exhaust duct 32 being integrated, and the CVT intake duct 22 and the CVT exhaust duct 32 being fastened together.

[0135] With this configuration, the CVT intake duct 22 and the CVT exhaust duct 32 are fastened together, so the integrated CVT intake duct 22, fan intake duct 23, and fan exhaust duct 33 can be fixed to the integrated engine intake duct 21 and CVT exhaust duct 32. This stabilizes the posture of all the ducts.

[0136] (Aspect 14) In the utility vehicle 100 described in any one of aspects 1 to 13, at least one of the opening ends of the engine intake duct 21 on the intake port 210 side, the opening end of the CVT intake duct 22 on the intake port 220 side, and the opening end of the fan intake duct 23 on the intake port 230 side has a filter mounting surface 25.

[0137] According to this configuration, at least one of the open ends of engine intake duct 21 on the intake port 210 side, the open end of CVT intake duct 22 on the intake port 220 side, and the open end of fan intake duct 23 on the intake port 230 side has a filter mounting surface 25. This allows a filter to be mounted on filter mounting surface 25 of at least one of the open ends.

[0138] (Aspect 15) The utility vehicle 100 described in any one of aspects 1 to 14 further includes a cargo bed 2 arranged behind the seat 6, and the at least one air intake port is arranged at a position higher than the upper end of the cargo bed 2.

[0139] According to this configuration, at least one air intake port is disposed at a position higher than the upper end of the cargo bed 2. This reduces the possibility of foreign matter being sucked in through the at least one air intake port.

[0140] (Aspect 16) The utility vehicle (100) according to any one of the first to fifteenth aspects further includes a seat belt (15), and the at least one air intake port is positioned higher than an upper end of the seat belt (15).

[0141] According to this configuration, at least one air intake port is disposed at a position higher than the upper end of seat belt 15. This can reduce the possibility of foreign matter being sucked in through at least one air intake port.

[0142] (Aspect 17) In the utility vehicle 100 according to any one of the first to sixteenth aspects, the at least one air intake port opens rearward.

[0143] According to this configuration, at least one air intake port opens to the rear, which reduces the chance of foreign matter scattered from the front to the rear being sucked in through the at least one air intake port while the utility vehicle 100 is traveling forward.

[0144] (Aspect 18) In the utility vehicle 100 described in any one of aspects 1 to 17, the intake port 210 of the engine intake duct 21, the intake port 220 of the CVT intake duct 22, and the intake port 230 of the fan intake duct 23 are arranged at intervals in the vehicle width direction.

[0145] With this configuration, the intake port 210 of the engine intake duct 21, the intake port 220 of the CVT intake duct 22, and the intake port 230 of the fan intake duct 23 are spaced apart in the vehicle width direction. This allows the three intake ports to be distributed in the vehicle width direction, reducing the risk of foreign matter being sucked in through all of the intake ports.

[0146] (Aspect 19) The utility vehicle 100 described in any one of aspects 1 to 18 further comprises a CVT exhaust duct 32 connected to the continuously variable transmission 12 and discharging internal air from the continuously variable transmission 12, and a fan exhaust duct 33 connected to the fan 13 and discharging internal air from the fan 13, and at least one of the CVT exhaust duct 32 and the fan exhaust duct 33 has a bent portion 35 midway along the path of the exhaust duct that extends upward and then downward as it moves from upstream to downstream.

[0147] According to this configuration, at least one of the exhaust ducts has bent portion 35, so even if foreign matter enters the exhaust port of the exhaust duct, the foreign matter is unlikely to enter upstream beyond bent portion 35. Therefore, it is possible to reduce the backflow of foreign matter through the exhaust duct.
