Description

Technical Field

[0001] This utility model relates to a straddle-type vehicle. Background Technology

[0002] For example, Patent Document 1 discloses a structure comprising: left and right grab bars fixed to the seat rail of a motorcycle; and a connecting portion below the rear seat connecting the left and right grab bars to each other, wherein an item storage portion is formed between the rear seat and the connecting portion.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2021-169276 Utility Model Content

[0004] The space under the rear seat is not only used for cargo storage, but also for the configuration of various electrical installation components found in recent years' motorcycle-style vehicles.

[0005] However, due to the vehicle's low-front, high-rear profile, the space at the rear of the vehicle and under the rear seats tends to narrow vertically towards the rear, limiting the space for component placement. With side walls and bottom walls as in Patent Document 1, the storage space becomes smaller. On the other hand, without these side walls and bottom walls, the stored items may be damaged. Therefore, a structure that utilizes seat rails and surrounding components to efficiently arrange vehicle components is desired.

[0006] The present invention was made in view of the above circumstances, and its purpose is to enable the efficient configuration of multiple vehicle components in a straddle-type vehicle in which vehicle components are configured between the seat and the seat rail.

[0007] In order to solve the above-mentioned problems and achieve the above-mentioned objectives, the present invention adopts the following solution.

[0008] <1> One embodiment of this utility model discloses a straddle-type vehicle comprising: a pair of left and right seat rails extending along the front-rear direction of the vehicle; a rear fender disposed at intervals below the seat rails; a seat disposed at intervals above the seat rails; and a support tray supporting vehicle components below the seat and between the left and right seat rails. The support tray comprises: a pair of left and right handles respectively engaged with the left and right seat rails; and a tray body extending along the width direction between the left and right handles to connect them and support the vehicle components. The tray body comprises an upper surface support portion supporting a first vehicle component (46A, 49A) on its upper surface and a lower surface support portion supporting a second vehicle component on its lower surface. The tray body and the handles are arranged at a height that overlaps when viewed from the side of the vehicle.

[0009] According to this structure, a rear seat and a rear fender are respectively positioned above and below the left and right seat tracks, and a support tray is erected between the left and right seat tracks. An upper surface support is provided on the upper surface of the tray body, which supports a first vehicle component between itself and the rear seat. A lower surface support is provided on the lower surface of the tray body, which supports a second vehicle component between itself and the rear fender. This vertically divides the space between the rear seat and the rear fender, allowing for the efficient placement of multiple vehicle components. By making the height of the tray body the same as the height of the left and right handles, multiple vehicle components can be efficiently placed vertically and vertically along the left and right seat tracks.

[0010] <2> In the above scheme <1> Alternatively, the straddle-type vehicle may have a pair of left and right rear support bars that support the seat rail from below. The seat rail extends at an angle that is lower in the front and higher in the rear when viewed from the side of the vehicle. The handle is tilted along the seat rail when viewed from the side of the vehicle. The tray body is formed along the upper surface of the fender when viewed from the side of the vehicle.

[0011] According to this structure, the rear fender extends along the rear support bar that supports the seat track from below, the handle of the support tray engages with the seat track along the seat track, and the tray body is formed along the gently sloping upper surface of the rear fender. Thus, the tray body reduces the slope and becomes approximately horizontal, stably supporting vehicle components on both the upper and lower surfaces. Furthermore, by twisting the tray body and the handle relative to each other, they can be configured to overlap when viewed from the side of the vehicle.

[0012] <3> In the above scheme <2> Alternatively, the second vehicle component may be mounted vertically from the lower surface support, and the second vehicle component may be separated from the upper surface of the mudguard.

[0013] According to this structure, a second vehicle component is supported vertically from the lower surface support portion. This second vehicle component is separated from the upper surface of the mudguard. As a result, the second vehicle component below the support tray can be supported, and contact between the second vehicle component and the rear mudguard is avoided, thus suppressing the generation of damage, noise, etc.

[0014] <4> In the above scheme <3> Alternatively, the rear fender may have an upper fender that supports a third vehicle component, which is different from the second vehicle component supported on the support tray, and the third vehicle component overlaps with the lower surface support portion when viewed from above.

[0015] According to this structure, the upper part of the rear fender has a mudguard that supports the third vehicle component, and the lower surface support overlaps with the third vehicle component when viewed from above. Thus, the space between the lower surface support and the rear fender can be effectively used as a configuration space for the third vehicle component, and the lower surface support and even the tray body can protect the third vehicle component from interference from above.

[0016] <5> In the above scheme <1> Alternatively, the support tray may have a wall extending vertically from the end of the tray body, and the wall has a tray rear locking portion that engages with the rear mudguard.

[0017] According to this structure, the lower end of the rear wall extending downward from the rear side of the support tray has a tray rear locking part that locks into the rear fender. Thus, the second vehicle component supported on the lower surface support can be bypassed and the support tray can be locked into the rear fender to fix the relative position. The rear wall also protects the second vehicle component from interference from the rear.

[0018] <6> In the above scheme <1> In this context, the first vehicle component may also be equipped with an onboard unit for an automatic payment system.

[0019] According to this structure, the ETC on-board unit is supported on the upper surface support, thereby enabling the ETC on-board unit with high access frequency to be installed in a way that is easy to operate (easy to open the cover).

[0020] <7> In the above scheme <1> Alternatively, a taillight unit may be provided behind the seat rail, the first vehicle component may have a sound generator that is configured to emit sound in the direction of the rear of the vehicle, the taillight unit may be configured at a position further rear than the rear end of the seat rail, and the sound generator may be configured separately in front of the taillight unit at a position further forward than the rear end of the seat rail.

[0021] According to this structure, the sound generator is configured to emit sound towards the rear of the vehicle, and a space is formed between the sound generator and the taillight unit. Thus, when the sound generator emits sound, the sound reverberates between the sound generator and the taillight unit, which can efficiently ensure the volume.

[0022] <8> In the above scheme <1> Alternatively, the straddle-type vehicle may have a lower crossbeam that connects the left and right seat rails to each other and supports the rear fender, with the support tray positioned above the lower crossbeam.

[0023] According to this structure, the support tray is positioned above the lower crossbeam that connects the left and right seat rails to each other. This allows for efficient configuration of the support tray and protects it from interference from below via the lower crossbeam.

[0024] <9> In the above scheme <8> Alternatively, the seat can be positioned above the support tray. The straddle-type vehicle has a front upper crossbeam connecting the left and right seat tracks on the front upper surface of the seat track and a rear upper crossbeam connecting the left and right seat tracks on the rear upper surface of the seat track. The front upper crossbeam and the rear upper crossbeam extend upward relative to the seat track and support the seat from below. The support tray is erected between the front upper crossbeam and the rear upper crossbeam on the left and right seat tracks. The tray body is positioned below the upper ends of the front upper crossbeam and the rear upper crossbeam.

[0025] According to this structure, the seat is supported above the front and rear crossbeams, and the tray body is positioned below the front and rear crossbeams. This allows for easy placement of vehicle components by ensuring storage space between the seat and the tray body, and the front and rear crossbeams protect the supporting tray from interference from above.

[0026] <10> In the above scheme <1> Alternatively, the lower surface of the pallet body may have a lower surface locking piece that extends downward and then along the lower surface of the lower surface support portion. The second vehicle component is surrounded by a covering member that has a slit forming portion into which the lower surface locking piece can be inserted. The second vehicle component is locked to the lower surface support portion (55) by inserting the lower surface locking piece into the slit forming portion.

[0027] According to this structure, a lower surface locking piece is inserted into the covering member that covers the second vehicle component, locking the second vehicle component to the lower surface support portion. This prevents contact between the second vehicle component and the support tray and rear fender, suppressing damage and noise. It simplifies the component support structure in the support tray, reducing the number of components, and allows for group assembly of the support tray and the second vehicle component.

[0028] <11> In the above scheme <1> Alternatively, the front end of the pallet body may have a front locking piece that extends forward toward the front of the vehicle body and then extends laterally along the front end of the pallet body, with the fourth vehicle component locking onto the front locking piece.

[0029] According to this structure, a fourth vehicle component is also supported by a locking piece at the front end of the pallet body, thereby enabling the support pallet to support more vehicle components.

[0030] <12> In the above scheme <1> Alternatively, the straddle-type vehicle may include: a first vertical wall extending downward from at least one left or right side end of the tray body; a second vertical wall extending downward from the handle portion on the same side as the first vertical wall in the left-right direction; and a bottom wall connecting the lower ends of the first and second vertical walls (63a, 63b), wherein an item storage portion capable of storing items is formed between the tray body and at least one left or right handle portion through the first and second vertical walls (63a, 63b) and the bottom wall.

[0031] According to this structure, an item storage section is formed between the tray body supporting the tray and at least one of the left and right handles, which can store items such as vehicle tools. This allows the stored items to be stored separately from other vehicle parts, and can prevent the stored items from contacting the vehicle parts and protect them.

[0032] According to the present invention, in a straddle-type vehicle in which vehicle components are arranged between the seat and the seat rail, multiple vehicle components can be efficiently arranged. Attached Figure Description

[0053] <Car Body Frame 5>

[0054] Figure 3 This is a left-side view showing the rear of the frame 5 of the motorized two-wheeled vehicle 1. Figure 4 This is a top view of the rear of the vehicle frame 5.

[0055] like Figure 1 , Figure 3 , Figure 4 As shown, the vehicle body frame 5 is formed by joining various types of steel together using welding and other methods. The vehicle body frame 5 includes: a head tube 6 located at the front end; a pair of left and right main frames 7 extending rearward and downward from the head tube 6; a pair of left and right pivot frames 8 extending downward from the rear lower ends of the left and right main frames 7; and a pair of left and right seat frames 9 extending rearward from the left and right main frames 7 and the left and right pivot frames 8. The left and right seat frames 9 include: seat rails 11 extending rearward from the rear of the left and right main frames 7 in a forward-lower-rear-higher manner; and rear support bars 12 extending rearward from the left and right pivot frames 8 below the left and right seat rails 11 in a forward-lower-rear-higher manner, supporting the rear of the left and right seat rails 11 from below. The left and right seat frames 9 are surrounded by a rear fairing 23.

[0056] <Engine 15>

[0057] like Figure 1 As shown, engine 15 has a crankshaft along the vehicle width direction (left-right direction) (only the rotation center axis (axis) C1 is shown). Engine 15 causes cylinder 17 to be erected above the front of crankcase 16. The intake passage of the engine intake system is connected to the rear of cylinder 17. The exhaust pipe of the engine exhaust system is connected to the front of cylinder 17. The clutch and transmission are housed in the rear of crankcase 16. The output shaft of the transmission protrudes to the left rear of crankcase 16. The output shaft is connected to rear wheel 13 via chain drive mechanism 24. The muffler 15b of the engine exhaust system is located on the right rear side of the vehicle body.

[0058] <Rear fender 30>

[0059] Figure 5 This is a sectional view of the left and right center of the vehicle body surrounding the rear seat 19b of the motorized two-wheeled vehicle 1. Figure 6 This is a top view of the area around the rear seat 19b. Figure 7 yes Figure 6 Sectional view VII-VII, Figure 8 yes Figure 6Sectional view VIII-VIII. In Figure 6 The rear seat 19b and the rear fairing 23 are omitted from the illustration.

[0060] like Figure 1 and Figures 5-7 As shown, a rear fender 30 is separately positioned between the left and right seat frames 9, above the rear wheel 13. The rear fender 30 is angled upwards, overlapping the left and right rear support strips 12 when viewed from the side. The rear fender 30 is, for example, a one-piece molded product made of synthetic resin.

[0061] Below the rear of the rear fender 30, a rear tail fender 38 is supported by a strut 37 extending from the lower surface of the rear fender 30 in a manner that is higher in the front and lower in the rear.

[0062] The rear fender 30 extends diagonally upward along the rear strut 12 and then bends at a near-horizontal angle above the rear wheel 13. The rear fender 30 can also bend along the outer circumference of the rear wheel 13 when viewed from the side. Figure 1 This illustrates the 1G state of the vehicle's weight acting on the front and rear suspensions. The rear fender 30 is at a specified distance from the outer periphery of the rear wheel 13. The rear fender 30 is fixed to the left and right seat frames 9 and crossbeams by means of fastening or locking.

[0063] The rear fender 30 is located below the rear seat 19b and vertically above the upper end (apex) 13b of the rear wheel 13 (also vertically above the axle 13a). When viewed from above, it forms a generally horizontal fender flat portion 31 at the point where it overlaps with the support tray 40 (described later). Compared to the rear fender 30 being inclined at the front and high at the rear, its generally horizontal configuration above the upper end of the rear wheel 13 makes it easier to ensure space between the rear fender 30 and the rear seat 19b, and facilitates the mounting of vehicle components by being generally horizontal.

[0064] <Seating Frame 9>

[0065] Reference Figure 3 , Figure 4 The seat rails 11 and rear support bars 12 of the left and right seat frames 9 extend at an angle that is lower in the front and higher in the rear when viewed from the side, and extend along the front-to-back direction of the vehicle when viewed from above. The seat rails 11 and rear support bars 12 are formed by, for example, round steel tubes of approximately the same diameter. The front parts of the seat rails 11 and rear support bars 12 on the same side are connected in a truss shape by a plurality of inclined tubes 9a.

[0066] Refer to together Figure 5 , Figure 6The rear portion 11b of the left and right seat rails 11, located near the rear end 11a (between the rear end 11a and the center of the rear seat 19b in a top-down view), is tilted in a way that the closer to the rear end 11a, the more inward it is in the vehicle width direction. The portion of the left and right seat rails 11 that is forward of each rear portion 11b extends in a straight line along the longitudinal direction of the vehicle in a top-down view. The reference numeral 11c in the figure indicates the bend of the left and right seat rails 11 located at the front end of the rear portion 11b in a top-down view. In a side view, the left and right seat rails 11 also have a downwardly protruding bend 11c2 at the joint where they engage with the tilting tube 9a. The portion from the bend 11c2 to the connecting portion 11d that connects to the main frame 7 has a gentler tilt in a side view compared to the portion further rear of the bend 11c2.

[0067] Viewed from above, the left and right rear support bars 12 are inclined approximately parallel to the rear portions 11b of the left and right seat tracks 11. Viewed from above, the left and right rear support bars 12 maintain this approximately parallel inclination to the rear portions 11b of the left and right seat tracks 11, reaching the connecting portion 12d that connects to the pivot frame 8. Viewed from the side, the left and right rear support bars 12 have upwardly protruding bent portions 12c formed below the rear portions 11b of the left and right seat tracks 11. The portion from the bent portion 12c to the rear end 12a (hereinafter referred to as the rear portion 12b of the left and right rear support bars 12) extends along the rear portion 11b of the left and right seat tracks 11. The rear portions 11b and 12b of the seat tracks 11 and rear support bars 12 on the same side are connected vertically to each other and joined together by welding or the like.

[0068] The rear parts of the left and right seat frames 9 are connected below the rear seat 19b by a front upper crossbeam 26, a rear upper crossbeam 27, and a rear lower crossbeam 28.

[0069] The upper front crossbeam 26 connects the left and right seat tracks 11 at a position forward of the front end (bent portion 11c) of the rear portion 11b of the left and right seat tracks 11. The upper front crossbeam 26 includes: an upper plate portion 26a, which is plate-shaped with its thickness direction pointing vertically and extends horizontally above the left and right seat tracks 11; and left and right side plate portions 26b, which bend downward from the left and right ends of the upper plate portion 26a and are respectively joined to the left and right seat tracks 11 by welding or the like. A seat locking mechanism (not shown) that keeps the detachable rear seat 19b in a locked state is supported on the lower surface of the upper plate portion 26a. A front flange 26c that bends downward and supports a lock cylinder 26d for operating the seat locking mechanism is formed at the front edge of the left and right center portions of the upper plate portion 26a. The front portion of the bottom plate of the rear seat 19b is supported on the upper surface of the upper plate portion 26a, thereby supporting the seating load of the rear seat 19b.

[0070] The rear upper crossbeam 27 connects the left and right seat tracks 11 at the rear end 11a of the left and right seat tracks 11. The rear upper crossbeam 27 includes: an upper plate portion 27a, which is plate-shaped with its thickness direction pointing vertically and extends horizontally above the left and right seat tracks 11; and left and right side plate portions 27b, which bend downward from the left and right sides of the upper plate portion 27a and are respectively joined to the left and right seat tracks 11 by welding or the like. A central cutout 27c, which is recessed to the rear and has a rectangular shape when viewed from above, is formed on the front side of the left and right center portions of the upper plate portion 27a. A front cutout 27d, which is trapezoidal in shape when viewed from above, is continuously formed on the front side of the central cutout 27c, and its width increases from left to right as it moves forward. A triangular opening 27e, which is formed on the rear side of the left and right inclined sides formed on the left and right sides of the front cutout 27d, is formed.

[0071] Here, a rear hook is formed on the lower rear surface of the base plate of the rear seat 19b, extending downward and then bending rearward. A central locking portion 27f is formed on the rear side of the central cutout 27c to lock the rear of the rear seat 19b. The rear seat 19b is tilted forward and backward so that the rear hook is locked into the central locking portion 27f of the upper rear crossbeam 27. Then, the front of the rear seat 19b is rotated in a downward manner, thereby engaging the latch on the lower surface of the base plate with the locking mechanism, and the installation of the rear seat 19b into the seat frame 9 is completed. The locking mechanism is released by operating the lock cylinder 26d, the front of the rear seat 19b is lifted and the rear hook is released, thereby removing the rear seat 19b.

[0072] The rear portion of the base plate of the rear seat 19b is supported on the upper surface of the upper plate portion 27a, thereby supporting the seating load of the rear seat 19b. The base plate of the rear seat 19b is inclined more gently than the left and right seat rails 11, with the front lower than the rear. The vertical width of the rear upper crossbeam 27 is smaller than the vertical width of the front upper crossbeam 26. The upper plate portion 27a of the rear upper crossbeam 27 extends to a position further rear than the rear end 11a of the left and right seat rails 11.

[0073] The rear lower crossbeam 28 includes: a lower plate portion 28a, which is plate-shaped with its thickness direction pointing vertically, extending horizontally below the left and right rear support bars 12; and left and right side plate portions 28b, which bend upwards from the left and right sides of the lower plate portion 28a and are respectively joined to the left and right rear support bars 12 by welding or the like. The lower plate portion 28a is inclined approximately parallel to the rear portion 12b of the left and right rear support bars 12 when viewed from the side. The lower plate portion 28a extends forward from the rear end 12a of the left and right rear support bars 12 to a position where it overlaps with the support tray 40 described later when viewed from above. The lower plate portion 28a includes multiple fastening portions 28c for fastening the base end (front upper end) of the support bar 37 of the rear fender 38 to the rear fender 30 together.

[0074] <Supporting tray 40>

[0075] Reference Figures 5-7 The front upper crossbeam 26 and the rear upper crossbeam 27 are separated from each other in the front-rear direction, and a support tray 40 for supporting multiple vehicle components is arranged between the front upper crossbeam 26 and the rear upper crossbeam 27.

[0076] Figure 9 This is a left-side view of the support tray 40 beneath the rear seat 19b. Figure 10 This is a right-side view of the support tray 40. Figure 11 This is a top view of the support tray 40. Figure 12 This is the front view of the support tray 40. Figure 13 This is a perspective view of the vehicle components mounted on the support tray 40.

[0077] Reference Figures 5-7 ,as well as Figures 9-13 The support tray 40 includes: a pair of left and right gripping portions 41 formed along the left and right seat tracks 11 and fitting into the outer periphery of the left and right seat tracks 11 from above; and a tray body 43 disposed between the left and right gripping portions 41 and formed into a generally horizontal rectangular plate shape. The support tray 40 is, for example, a one-piece molded product made of synthetic resin. (See reference...) Figure 6 A wiring harness is provided around the support tray 40 to connect to the lights at the rear of the vehicle body, vehicle components on the support tray 40, etc. For example, a ring-shaped wiring harness locking part 41a is provided on the upper surface of the front and rear middle part of the left handle 41 for locking the wiring harness (coupler) ha by a locking member such as a cable tie.

[0078] The support tray 40 is positioned approximately horizontally relative to the left and right grips 41, which are inclined at the front and lower at the rear. The tray body 43 and the left and right grips 41 are set at a height that overlaps each other when viewed from the side. When viewed from the side, the left and right grips 41 and the tray body 43 have different inclination angles. The support tray 40 is in a twisted shape between the left and right grips 41 and the tray body 43. The tray body 43 is positioned so as to traverse the rear part 11b of the seat track 11, which is inclined at the front and lower at the rear when viewed from the side, along the front and rear direction. When viewed from above, the rear part of the tray body 43 overlaps with the front part of the rear lower crossbeam 28. The rear part of the tray body 43 and the front part of the rear lower crossbeam 28 are separated from each other in the vertical direction to prevent them from contacting each other. When viewed from above, an outer peripheral wall 43a is formed on the front and left and right sides of the tray body 43, which rises upward relative to the flat portion of the tray body 43.

[0079] The pallet body 43 has a rear wall 44 extending downward from the rear end. The rear wall 44 has a pallet rear locking portion 44a extending rearward from the lower end and capable of locking onto the rear fender 30. The pallet rear locking portion 44a is fastened to a boss 32 protruding from the upper surface of the rear fender 30. For example, two bosses 32 are arranged in a front-to-back configuration to accommodate changes in the size of the pallet body 43. The rear fender 30 is mounted from below to the lower plate portion 28a of the rear lower crossbeam 28 around the boss 32. An opening 28d is formed in the lower plate portion 28a, allowing the boss 32 to protrude upward from the lower surface of the lower plate portion 28a. Multiple (e.g., four) fastening portions 28c are provided around the opening 28d. The area around the boss 32 of the rear fender 30 and the base end (front upper end) of the support strip 37 of the rear tail fender 38 are sequentially overlapped on the lower plate portion 28a from below, and they are fastened together at multiple fastening portions 28c.

[0080] The tray's rear locking part 44a is fastened to the boss 32 of the rear fender 30 by bolts, thereby positioning the support tray 40 relative to the rear fender 30 and even the left and right seat frames 9. The rear part 11b of the left and right seat tracks 11 is configured as follows (viewed from above) The position of the support tray 40 can be roughly determined by simply engaging the left and right grips 41 with the rear part 11b of the left and right seat rails 11. However, by fastening the rear locking part 44a of the tray to the boss 32 of the rear fender 30, the positioning of the support tray 40 can be made more reliable.

[0081] A buzzer (sound emitter, alarm) 46 of an anti-crime device is supported on the upper surface of the tray body 43 via an L-shaped support 45 (viewed from the side) as a first vehicle component 46A. The buzzer 46 is approximately cuboid in shape, with its rear surface 47 facing rearward as the sound-emitting surface, so that the sound direction is towards the rear. The buzzer 46 is disposed adjacent to the rear edge of the tray body 43, with the longitudinal plate of the support 45 fixed to the front surface and the transverse plate of the support 45 fixed to the upper surface of the tray body 43. The lower part of the buzzer 46 is located below the tray body 43. In other words, the buzzer 46 is offset downward relative to the tray body 43. The upper surface of the tray body 43 forms an upper surface support portion 48 that supports the first vehicle component 46A.

[0082] Refer to together Figure 8As another embodiment, an ETC (Electronic Toll Collection) device, such as an automatic toll collection system device, can also be mounted on the upper surface of the tray body 43 as another first vehicle component 49A. The ETC device has a flat cuboid shape with its thickness dimension suppressed, and is arranged with its thickness direction facing vertically. The ETC device is fixed to the tray body 43 by various fixing means (e.g., double-sided tape). Depending on the size of the ETC device, the vehicle component supported on the upper surface of the support tray 40 is either the ETC device or the buzzer 46.

[0083] A second vehicle component 51A, for example, is supported on the lower surface side of the tray body 43 as a Bluetooth (Bluetooth: registered trademark) unit.

[0084] A lower surface retaining piece 52 is formed on the inner side of the tray body 43 when viewed from above, in a shape that causes the flat portion of the tray body 43 to shift downward. The lower surface retaining piece 52 extends forward parallel to the lower surface of the tray body 43 from the hanging wall 52a, which hangs down from the lower surface of the tray body 43. The lower surface retaining piece 52 is inserted into a slit forming portion 54 formed in (or formed on) the covering member 53 that covers the case of the Bluetooth unit 51, thereby supporting the Bluetooth unit 51 on the lower surface side of the tray body 43. The lower surface side of the tray body 43 becomes a lower surface support portion 55 that supports the second vehicle component 51A. A protrusion 52b is formed on the front end of the lower surface retaining piece 52, for example, in the width direction, to prevent the slit forming portion 54 from falling off.

[0085] A front extension 56 is formed at the front of the pallet body 43, extending the flat portion of the pallet body 43 forward. The front extension 56 includes: an extension 56a formed at the front of the left side of the pallet body 43 and flush with the flat portion of the pallet body 43; and a front locking piece 56b extending to the right from the right end of the extension 56a. An alarm control device 57, for example, is supported on the front locking piece 56b as a fourth vehicle component 57A. The front locking piece 56b is inserted into a track portion 58 formed in the housing of the alarm control device 57 (or in a covering member that covers the housing), thereby supporting the alarm control device 57 on the lower surface side of the front extension 56 of the pallet body 43.

[0086] Here, a taillight unit 34 is supported at the rear end of the rear fender 30. The taillight unit 34 is spatially positioned behind (in the direction of sound emission) the buzzer 46. Specifically, the front end 34a of the taillight unit 34 is located further rearward than the rear end of the seat frame 9, and the rear surface 47 of the buzzer 46 is located further forward than the rear end of the seat frame 9. Because space is ensured along the direction of sound emission of the buzzer 46, the sound emission of the buzzer 46 is not obstructed and can be emitted well.

[0087] The tray body 43 is positioned in the upper and lower middle part of the space between the rear seat and the rear fender 30. First vehicle components 46A and 49A are disposed between the tray body 43 and the rear seat, and second vehicle components 51A and fourth vehicle components 57A are disposed between the tray body 43 and the rear fender 30. The support tray 40 is mounted on the left and right seat rails 11 and is not locked or abutted against the rear fender 30 except for the rear tray locking part 44a.

[0088] A mudguard flat portion 31 is formed in the rear mudguard 30 at a location below the pallet body 43. This mudguard flat portion 31 forms a generally horizontal upper surface (mudguard upper surface 31a). The mudguard flat portion 31 is inclined relative to the rear support bar 12, which is inclined at the front and upward at the rear when viewed from the side. The mudguard flat portion 31 is positioned to overlap with the pallet body 43 when viewed from above. The mudguard flat portion 31 is separated downward from the second vehicle component 51A and the fourth vehicle component 57A, which are supported on the lower surface side of the pallet body 43.

[0089] A third vehicle component 61A, such as a Body Control Unit (BCU) 61, is supported on the flat portion 31 of the fender. The Body Control Unit 61 is a flat cuboid with reduced thickness in the vertical direction and is positioned forward of the rear lower crossbeam 28. The Body Control Unit 61 has a thicker front portion than a thicker rear portion, giving it a stepped upper surface shape when viewed from the side. The front portion of the Body Control Unit 61 is located below the front locking plate 56b and the alarm control device 57, and is arranged to overlap when viewed from above.

[0090] The Bluetooth unit 51, supported on the tray body 43, protrudes downwards at a greater height than the alarm control device 57, which is supported on the front locking tab 56b. Both the Bluetooth unit 51 and the alarm control device 57 are arranged with equal spacing relative to the vehicle control unit 61. The second vehicle component 51A and the fourth vehicle component 57A on the side of the tray body 43 and the third vehicle component 61A on the side of the rear fender 30 are configured with different concave and convex shapes, enabling efficient arrangement of multiple vehicle components.

[0091] A concave item storage section 63 is formed between the tray body 43 and the handle portion 41 on the left and right sides (right side in the figure) for holding items 64 such as vehicle tools, documents, etc. The item storage section 63 has: an inner wall (first downward wall) 63a extending downward from the outer side of the tray body 43; an outer wall (second downward wall) 63b extending downward from the inner side of the handle portion 41; and a bottom wall 63c between the lower ends of the inner and outer walls 63a and 63b. The item storage section 63 has an upwardly opening U-shaped cross-section and extends in the front-rear direction. An elastic band 65 for holding the item 64 can be mounted in the upper opening of the item storage section 63. A guide wall 43b is formed on the right side of the tray body 43 to facilitate the storage of the item 64 into the item storage section 63. An elongated opening 63d is formed along the seat track 11 in the second downward wall 63b.

[0092] The rear fender 30 is inclined so as to overlap with the rear support bar 12 when viewed from the side. A generally horizontal fender flat portion 31 is formed in the part of the rear fender 30 that overlaps with the support tray 40 when viewed from above. As a result, space between the rear fender 30 and the rear seat 19b is easily ensured above the rear wheel 13, making it easy to mount vehicle parts.

[0093] As described above, the straddle-type vehicle of the above embodiment is a motorized two-wheeled vehicle 1, which includes: a pair of left and right seat rails 11, which are disposed at the rear of the vehicle frame 5 and extend along the longitudinal direction of the vehicle; a rear fender 30, which is disposed at intervals below the left and right seat rails 11; a rear seat 19b, which is disposed at intervals above the left and right seat rails 11; and a support tray 40, which supports vehicle components below the rear seat 19b and between the left and right seat rails 11, wherein the support tray 40 has The tray body 43 is provided with a pair of left and right gripping portions 41 that are respectively locked onto the left and right seat rails 11, and a tray body 43 that extends between the left and right gripping portions 41 in the vehicle width direction to connect the left and right gripping portions 41 and support the vehicle components. The tray body 43 has an upper surface support portion 48 that supports the first vehicle components 46A and 49A on the upper surface side and a lower surface support portion 55 that supports the second vehicle component 51A on the lower surface side. The tray body 43 and the gripping portions 41 are arranged at a height that overlaps each other when viewed from the side of the vehicle.

[0094] According to this structure, a rear seat 19b and a rear fender 30 are respectively arranged above and below the left and right seat tracks 11. A support tray 40 is erected between the left and right seat tracks 11. An upper surface support portion 48 is provided on the upper surface of the tray body 43, which can support first vehicle components 46A and 49A between it and the rear seat 19b. A lower surface support portion 55 is provided on the lower surface of the tray body 43, which can support second vehicle component 51A between it and the rear fender 30. In this way, the space formed between the rear seat 19b and the rear fender 30 is divided vertically, allowing for the efficient arrangement of multiple vehicle components. By making the height of the tray body 43 the same as the height of the left and right handle portions 41, multiple vehicle components can be efficiently arranged vertically and vertically on the left and right seat tracks 11.

[0095] In the aforementioned motorized two-wheeled vehicle 1, there is a pair of left and right rear support bars 12 that support the left and right seat rails 11 from below. The left and right seat rails 11 extend at an angle that is lower in the front and higher in the rear when viewed from the side of the vehicle. The left and right rear support bars 12 extend at an angle that is steeper than the seat rails 11 when viewed from the side of the vehicle. The rear mudguard 30 extends along the rear support bars 12 when viewed from the side of the vehicle, and forms a mudguard upper surface 31a above the rear wheel 13 to reduce the angle that is lower in the front and higher in the rear. The left and right handles 41 are inclined along the seat rails 11 when viewed from the side of the vehicle and are respectively locked onto the left and right seat rails 11 on the same side. The tray body 43 is formed along the mudguard upper surface 31a when viewed from the side of the vehicle.

[0096] According to this structure, the rear fender 30 extends along the rear support bar 12 that supports the seat rail 11 from below, the handle 41 of the support tray 40 is engaged with the seat rail 11 along the seat rail 11, and the tray body 43 is formed along the gently sloping upper surface 31a of the rear fender 30. Thus, the tray body 43 reduces the slope and becomes approximately horizontal, stably supporting vehicle components on both its upper and lower surfaces. Furthermore, by twisting the tray body 43 and the handle 41 relative to each other, they can be configured to overlap when viewed from the side of the vehicle.

[0097] In the above-mentioned motorized two-wheeled vehicle 1, the second vehicle component 51A is mounted vertically from the lower surface support portion 55, and the second vehicle component 51A is separated from the upper surface 31a of the mudguard.

[0098] According to this structure, the second vehicle component 51A is supported vertically from the lower surface support portion 55. The second vehicle component 51A is separated from the upper surface 31a of the mudguard. Thus, the second vehicle component 51A below the support tray 40 can be supported, and the contact between the second vehicle component 51A and the rear mudguard 30 is avoided, thereby suppressing the generation of damage, noise, etc.

[0099] In the aforementioned motorized two-wheeled vehicle 1, the rear mudguard 30 has a mudguard flat portion 31 that supports a third vehicle component 61A, which is different from the second vehicle component 51A supported on the support tray 40. The third vehicle component 61A and the lower surface support portion 55 overlap each other when viewed from above.

[0100] According to this structure, the rear fender 30 has a flat fender portion 31 that supports the third vehicle component 61A. The lower surface support portion 55 overlaps with the third vehicle component 61A when viewed from above. Thus, the space between the lower surface support portion 55 and the rear fender 30 can be effectively used as a configuration space for the third vehicle component 61A, and the lower surface support portion 55 and even the tray body 43 can protect the third vehicle component 61A from interference from above.

[0101] In the aforementioned motorized two-wheeled vehicle 1, the support tray 40 has a rear wall 44 extending downward from the rear side of the tray body 43, and a tray rear locking part 44a that is locked to the rear mudguard 30 is provided at the lower end of the rear wall 44.

[0102] According to this structure, the lower end of the rear wall 44 extending downward from the rear side of the support tray 40 has a tray rear locking part 44a that locks onto the rear fender 30. Thus, the second vehicle component 51A supported on the lower surface support part 55 can be bypassed and the support tray 40 can be locked onto the rear fender 30 to fix the relative position. The rear wall 44 also protects the second vehicle component 51A from interference from the rear.

[0103] In the aforementioned motorized two-wheeled vehicle 1, the first vehicle component 49A has an on-board unit 49 for an automatic toll collection (ETC) system and is supported on the upper surface support portion 48.

[0105] In the aforementioned motorized two-wheeled vehicle 1, a taillight unit 34 is provided behind the seat rail 11, and the first vehicle component 46A is provided with a sound generator (buzzer 46). The buzzer 46 is supported by a support bar 45 on the upper surface support portion 48 and is offset downward relative to the upper surface support portion 48. The sound emission direction is directed towards the rear of the vehicle. The taillight unit 34 is located behind the rear end 11a of the seat rail 11, and the buzzer 46 is located in front of the taillight unit 34, separated from the rear end 11a of the seat rail 11.

[0106] According to this structure, the buzzer 46 is configured to emit sound towards the rear of the vehicle, and a space is formed between the buzzer 46 and the taillight unit 34. Thus, when the buzzer 46 emits a sound, the sound reverberates between the buzzer 46 and the taillight unit 34, which can efficiently ensure the volume.

[0107] In the aforementioned motorized two-wheeled vehicle 1, a rear lower crossbeam 28 is provided to connect the left and right seat rails 11 to each other (the rear support bars 12 to each other) and to support the rear mudguard 30, and the support tray 40 is disposed above the rear lower crossbeam 28.

[0108] According to this structure, the support tray 40 is supported above the rear lower crossbeam 28 that connects the left and right seat rails 11 to each other. This allows for efficient support of the support tray 40 and protects it from interference from below via the rear lower crossbeam 28.

[0109] In the aforementioned motorized two-wheeled vehicle 1, the rear seat 19b is arranged above the support tray 40. The motorized two-wheeled vehicle 1 has a front upper crossbeam 26 that connects the left and right seat tracks 11 on the front upper surface side of the seat track 11 and a rear upper crossbeam 27 that connects the left and right seat tracks 11 on the rear upper surface side of the seat track 11. The front upper crossbeam 26 and the rear upper crossbeam 27 extend upward relative to the seat track 11 and support the rear seat 19b from below. The support tray 40 is erected between the front upper crossbeam 26 and the rear upper crossbeam 27 on the left and right seat tracks 11. The tray body 43 is arranged at a position lower than the upper ends of the front upper crossbeam 26 and the rear upper crossbeam 27.

[0110] According to this structure, the rear seat 19b is supported above the front and rear crossbeams 26 and 27, and the pallet body 43 is positioned below the front and rear crossbeams 26 and 27. This ensures that there is storage space for components between the rear seat 19b and the pallet body 43, making it easy to arrange vehicle components. The front and rear crossbeams 26 and 27 also protect the support pallet 40 from interference from above.

[0111] In the above-described motorized two-wheeled vehicle 1, the lower surface of the pallet body 43 has a lower surface locking piece 52 that extends downward and then extends along the lower surface of the lower surface support portion 55. The second vehicle component 51A is surrounded by a covering member 53. The covering member 53 has a slit forming portion 54 into which the lower surface locking piece 52 can be inserted. The second vehicle component 51A is locked to the lower surface support portion 55 by inserting the lower surface locking piece 52 into the slit forming portion 54.

[0112] According to this structure, the lower surface locking piece 52 is inserted into the covering member 53 that covers the second vehicle component 51A, locking the second vehicle component 51A to the lower surface support portion 55. This prevents contact between the second vehicle component 51A and the support tray 40 and the rear fender 30, suppressing damage and noise. The component support structure in the support tray 40 can be simplified, reducing the number of components, and allowing for group assembly of the support tray 40 and the second vehicle component 51A.

[0113] In the aforementioned motorized two-wheeled vehicle 1, the front end of the pallet body 43 has a front end locking piece 56b that extends forward toward the front of the vehicle body and then extends along the front end of the pallet body 43, and the fourth vehicle component 57A is locked to the front end locking piece 56b.

[0114] According to this structure, the front locking piece 56b of the tray body 43 also supports a fourth vehicle component 57A, thereby enabling the support tray 40 to support more vehicle components.

[0115] The aforementioned motorized two-wheeled vehicle 1 includes: a first vertical wall 63a extending downward from at least one of the left and right side ends of the tray body 43; a second vertical wall 63b extending downward from the handle portion 41 on the same side as the first vertical wall 63a in the left-right direction; and a bottom wall 63c connecting the lower ends of the first and second vertical walls 63a and 63b, wherein an item storage portion 63 capable of storing items 64 is formed between the tray body 43 and the handle portion 41 on at least one of the left and right sides through the first and second vertical walls 63a and 63b and the bottom wall 63c.

[0116] According to this structure, an item storage section 63 is formed between the tray body 43 of the support tray 40 and the handle 41 on at least one side, which is capable of storing items 64 such as vehicle tools. As a result, the stored items can be stored separately from other vehicle parts, and the stored items can be protected from contact with vehicle parts.

[0117] This invention is not limited to the embodiments described above. For example, in one embodiment, an electrical installation component of a vehicle and supporting struts, brackets, etc., attached to the electrical installation component are shown as vehicle components supported on a support tray. However, the arrangement of each component and the presence or absence of supporting struts, etc., can be appropriately changed. Supports can also be provided for control devices, electrical installation components, or other vehicle components other than those illustrated.

[0118] The structure of this embodiment can also be applied to straddle-type vehicles other than motorized two-wheelers. The straddle-type vehicles include all vehicles in which the driver straddles the vehicle, including not only motorized two-wheelers (including bicycles and scooter-type vehicles with a prime mover), but also three-wheeled (including vehicles with two front wheels and one rear wheel, in addition to those with one front wheel and two rear wheels) or four-wheeled (four-wheeled carts, etc.) vehicles. It can also be applied to vehicles whose prime mover includes an electric motor.
