[0002] A straddle-type vehicle is formed with a structure for holding vehicle parts such as a fuel tank. One known example of such a vehicle part holding structure is one in which a fuel tank is held by a pair of rear frames (see, for example, Patent Document 1). The fuel tank is formed with a flange formed by joining the outer edges of an upper shell and a lower shell. The pair of rear frames extend diagonally upward from the front to the rear, and brackets are provided at two locations, front and rear, on each rear frame to support the fuel tank flange from below. The fuel tank flange is fastened with screws to the two brackets, front and rear, on each rear frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-118629 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the vehicle component retention structure described in Patent Document 1 cannot have a structure in which the pair of rear frames and the flange of the fuel tank are too far apart, which may restrict the shapes of the pair of rear frames and the fuel tank. For this reason, a retention structure that holds the fuel tank to the rear fender has also been proposed to allow for greater freedom in the shapes of the pair of rear frames and the fuel tank. In this case, a clip nut is used to secure the fuel tank flange, but forming an attachment point for the clip nut requires cutting out a portion of the rear fender or forming an opening in the rear fender. When the clip nut is attached to the rear fender, a gap is formed around the clip nut, which may allow foreign matter, such as muddy water splashed up by the rear wheel, to enter and accumulate inside the rear fender.

[0005] The present invention has been made in consideration of the above points, and provides a vehicle part holding structure that can prevent foreign matter from entering the rear fender and can properly hold vehicle parts in the rear fender. and fuel tank holding structure The purpose is to provide. [Means for solving the problem]

[0006] A vehicle part retention structure according to one aspect of the present invention is a vehicle part retention structure formed on a rear fender, and includes a nut having a flange that protrudes radially outward from a cylindrical female thread, and a support portion that supports the vehicle part from below on the rear fender, wherein the support portion is formed so that the nut can be attached from below the rear fender, and the support portion is formed with an opening into which the female thread fits, a fitting portion that positions the flange, and a plurality of claw portions that hook the flange from below, At least one of the plurality of claw portions extends downward from the lower surface of the support portion and then is folded back in a U-shape so that the tip of the claw faces upward, before record At least one Claw When the flange comes into contact with the support portion from below, the at least one claw portion bends, allowing the nut to be attached to the support portion, thereby solving the above problem. [Effects of the Invention]

[0007] According to one aspect of the vehicle component retention structure of the present invention, even if a nut is pushed toward the support portion from the underside of the rear fender and the flange of the nut contacts at least one of the multiple claws, the claws deflect, allowing the nut to be attached to the support portion. When the nut is attached to the support portion, the fitting portion positions the nut so that it cannot rotate, and the multiple claws prevent the nut from falling off. This allows the vehicle component to be easily screwed onto the female thread of the nut exposed through the opening in the support portion. Furthermore, because the opening in the support portion is covered from below by the flange, no gap is created when the nut is attached to the support portion, preventing foreign matter such as muddy water from entering the inside of the rear fender.

[0009] A vehicle component holding structure according to one aspect of the present invention is formed on a rear fender. The rear fender is formed with a support portion that supports the vehicle component from below, and a nut is attached to the support portion from below the rear fender. The nut has a flange that extends radially outward from a cylindrical female thread. The support portion is formed with an opening into which the female thread fits, a fitting portion that positions the flange, and multiple claws that latch the flange from below. When the nut is pushed toward the support portion from below the rear fender and the flange contacts at least one of the multiple claws from below, the claws bend, allowing the nut to be attached to the support portion. When the nut is attached to the support portion, the fitting portion positions the nut so that it cannot rotate, and the multiple claws prevent the nut from falling off. This allows the vehicle component to be easily screwed onto the female thread of the nut exposed through the opening in the support portion. Furthermore, the opening in the support portion is covered from below by the flange, eliminating any gaps when the nut is attached to the support portion, preventing foreign matter such as muddy water from entering the inside of the rear fender. [Example]

[0010] This embodiment will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view of the saddle-ride type vehicle of this embodiment as seen from below. FIG. 2 is a top view of the rear part of the vehicle with the seat removed. In the following description, a scooter-type motorcycle will be used as an example of the saddle-ride type vehicle. Also, a fuel tank will be used as an example of the vehicle part. In the following drawings, arrow FR indicates the front of the vehicle, arrow RE indicates the rear of the vehicle, arrow L indicates the left side of the vehicle, and arrow R indicates the right side of the vehicle.

[0011] As shown in Figures 1 and 2, the exterior of the rear portion of the saddle-ride type vehicle 1 is formed by a plurality of cover members. The left and right side surfaces of the rear portion of the vehicle are formed by a pair of left and right rear side covers 11, and the rear surface of the rear portion of the vehicle is formed by a rear center cover 12. The lower surface of the rear portion of the vehicle is formed by a rear fender 13, and the upper surface of the rear portion of the vehicle is formed by a tank cover 14. These top, bottom, left, right and rear cover members form a storage space for a fuel tank 25 (see Figure 4). The plurality of cover members are attached to each other by one or more attachment methods such as screw fastening, hook fastening, clip fastening, etc.

[0012] A helmet box 15 is disposed in front of the rear fender 13 and the tank cover 14, and a unit swing engine 21 is disposed below the helmet box 15. The unit swing engine 21 is swingably supported on the body frame 17 via a suspension bracket 18, and a rear wheel 24 is rotatably supported at the rear of the unit swing engine 21. A CVT cover 22 is attached to the left side of the unit swing engine 21. A belt-type continuously variable transmission (not shown) is housed inside the CVT cover 22, and the driving force of the unit swing engine 21 is transmitted to the rear wheel 24 via the belt.

[0013] In the saddle-type vehicle 1 of this embodiment, the fuel tank 25 (see FIG. 4) is attached to the rear fender 13. In order to screw the fuel tank 25 to the rear fender 13, it is necessary to hold down the nuts on the underside of the rear fender 13 with a tool or the like, but the helmet box 15 is located in front of the fuel tank 25, making this work cumbersome. In places where the working space is narrow, clip nuts are sometimes used. The use of clip nuts eliminates the need to weld the nuts to the rear fender 13, and also eliminates the need to hold down the nuts when tightening, allowing work to be done in places where it is difficult for the worker to reach their fingers.

[0014] For example, in the comparative example shown in Fig. 3A, a notch is formed in the bottom wall of rear fender 61, and clip nut 64 is attached to the side of the side edge of notch 62. A gap 65 is formed on the side of clip nut 64, and there is a risk that foreign matter such as muddy water splashed up by the rear wheel may enter the inside (upper side) of rear fender 61 through gap 65. Furthermore, in the comparative example shown in Fig. 3B, an opening is formed in the bottom wall of rear fender 71, and clip nut 74 is attached from opening 72 toward the edge of the opening. A large gap 75 is formed on the side of clip nut 74, making it easy for foreign matter to enter the inside of rear fender 71 through gap 75.

[0015] Furthermore, the clip nuts 64, 74 have female threads formed by burring a thin plate. It is difficult to ensure sufficient thread strength with the clip nuts 64, 74 against the tightening torque of the bolt, and a thread locking agent must be used in conjunction with the clip nuts 64, 74 to prevent the threads from loosening. As such, gaps 65, 75 are created when the clip nuts 64, 74 are attached to the rear fenders 61, 71 from the side, and the clip shape of the clip nuts 64, 74 makes a thread locking agent necessary. Therefore, this embodiment employs a fuel tank retention structure that allows the nuts to be attached to the rear fender 13 from below with a single touch, eliminating the need for a thread locking agent.

[0016] The fuel tank holding structure will be described with reference to Figures 4 to 9. Figure 4 is a cross-sectional view of the rear of the vehicle in Figure 2 taken along line AA. Figure 5 is a cross-sectional view of the rear of the vehicle in Figure 4 taken along line BB. Figure 6 is a perspective view of the nut of this embodiment. Figure 7 is a perspective view of the support part of the rear fender of this embodiment seen from below. Figure 8 is a bottom view showing the installation location of the nut of this embodiment. Figure 9 is a cross-sectional view of the installation location of the nut in Figure 8 taken along line CC.

[0017] 4 and 5, the bottom surface of the rear fender 13 bulges downward to form a recess 31, and the lower part of the fuel tank 25 is housed inside this recess 31 of the rear fender 13. A front end 32 and both left and right ends 33 of the rear fender 13 are located higher than the bottom surface of the recess 31, and the upper surfaces of the front end 32 and both left and right ends 33 face the flange 26 of the fuel tank 25. A helmet box 15 is disposed in front of the rear fender 13, and the helmet box 15 protrudes downward beyond the front end 32 of the rear fender 13. The front end 32 of the rear fender 13 is sandwiched from the front and rear by the recess 31 and the helmet box 15.

[0018] A total of four support portions 35 that support the flange 26 of the fuel tank 25 from below are formed at two locations on both the left and right sides of the front end portion 32 of the rear fender 13 and two locations on the rear sides of both left and right ends 33 of the rear fender 13. The support portions 35 are formed so that nuts 55 can be attached from the underside of the rear fender 13, and because the nuts 55 will not fall off the rear fender 13, there is no need to hold the nuts 55 against the underside of the support portions 35 with a tool or the like when screwing the fuel tank 25 in place. Attaching the nuts 55 to the rear fender 13 forms threaded holes in the rear fender 13, and bolts 29 are tightened into the threaded holes from above to fix the flange 26 of the fuel tank 25 to the support portions 35.

[0019] As shown in FIG. 6, the nut 55 is formed with a cylindrical female thread 56 and a flange 57, and is generally hat-shaped in cross section. The female thread 56 protrudes from the upper surface of the flange 57, and a screw hole 58 into which the bolt 29 (see FIG. 4) is fastened penetrates the center of the female thread 56. The flange 57 protrudes radially outward from the lower part of the female thread 56, and the outer edge of the flange 57 is formed in a square shape. Because the outer edge of the flange 57 is rotationally symmetrical by 90 degrees, the nut 55 can be attached to the support part 35 even if the front, back, left, and right of the nut 55 are reversed. The four corners of the flange 57 are chamfered, which improves the ease of attachment and detachment of the nut 55.

[0020] As shown in FIG. 7, a square-frame-shaped fitting portion 38 protrudes from the underside of the upper wall 36 of the support portion 35. The inside of the fitting portion 38 forms a mounting surface 39 for a nut 55 (see FIG. 6), and a substantially circular opening 41 is formed in the center of the mounting surface 39. Rectangular notches are cut out from the edge of the circular opening toward two opposing sides of the fitting portion 38, and the mounting surface 39 is divided into two by the opening 41 and notches 42 and 43. On the outside of the mounting surface 39, a first claw portion 44 is formed adjacent to the notch 42, and a second claw portion 47 is formed adjacent to the notch 43. The first and second claw portions 44 and 47 face each other across the opening 41, and claw tips 45 and 48 of the first and second claw portions 47 extend into the mounting surface 39.

[0021] The first claw 44 extends downward from the underside of the upper wall 36 of the support part 35 and is then folded back in a U-shape so that the toe 45 faces upward. The U-shaped folded shape of the first claw 44 provides flexibility to the first claw 44. An apex 46 of the folded portion of the first claw 44 protrudes downward, and this apex 46 is located outside the mounting surface 39. The second claw 47 extends downward from the underside of the upper wall 36 of the support part 35 and has a toe 48 protruding inward from the lower end of the second claw 47. Sloped guide surfaces 51, 52 are formed on the outer surface of the first claw 44 from the apex 46 to the toe 45 and on the outer surface of the second claw 47 from the lower end to the toe 48 so as to guide the nut 55 to the mounting surface 39.

[0022] 8 and 9, nut 55 is attached to support portion 35 of rear fender 13 from below. At this time, flange 57 of nut 55 abuts against attachment surface 39 of support portion 35, and internal thread 56 of nut 55 fits into central opening 41 of attachment surface 39. Flange 57 of nut 55 is fitted inside square frame-shaped fitting portion 38, and square flange 57 is positioned by fitting portion 38 so that it cannot rotate. Flange 57 is latched from below by first and second claw portions 44, 47, and toes 45, 48 of first and second claw portions 44, 47 prevent nut 55 from falling off attachment surface 39.

[0023] The fixing holes 27 in the flange 26 of the fuel tank 25 are aligned with the threaded holes 58 of the female thread 56, and the bolts 29 inserted into the fixing holes 27 are tightened into the threaded holes 58 of the female thread 56. In this case, the support part 35 is formed into an inverted concave shape in cross section by the top wall 36 to which the nut 55 is attached and the side walls 37 that surround the nut 55. The side walls 37 of the support part 35 increase the rigidity around the nut 55, and deformation of the support part 35 is suppressed even when the flange 26 of the fuel tank 25 is tightly screwed into the female thread 56. In addition, the side walls 37 of the support part 35 narrow the space below the nut 55, making it difficult for foreign matter such as mud or water to adhere to the nut 55 from below.

[0024] Furthermore, by attaching the nut 55 to the support portion 35, the opening 41 and the notches 42, 43 (see FIG. 7) of the attachment surface 39 are covered from below by the flange 57 of the nut 55. Therefore, foreign matter such as muddy water splashed up by the rear wheel will not enter the upper side of the rear fender 13 through the opening 41 of the support portion 35. With this structure, the fuel tank 25 can be fixed to the rear fender 13 in the same way as when an insert nut is provided on the rear fender 13. However, unlike the attachment of an insert nut, this embodiment does not require insert molding or press processing for integration during resin molding, thereby reducing the occurrence of problems during processing.

[0025] The work of fixing the fuel tank to the rear fender will be described with reference to Fig. 10. Fig. 10 is an explanatory view of the work of fixing the fuel tank in this embodiment. Note that Fig. 10 illustrates the work of fixing the fuel tank at the support portion at the front end of the rear fender.

[0026] As shown in FIG. 10(A), when attaching the nut 55 to the rear fender 13, the nut 55 is brought close to the attachment surface 39 of the support portion 35 from below. Because the inside of the support portion 35 is formed narrow, the nut 55 is pushed into the rear side of the support portion 35 with a fingertip. When the outer edge of the flange 57 comes into contact with the first claw portion 44 from below, the first claw portion 44 begins to bend outward, allowing movement of the nut 55 in the attachment direction. At this time, the apex 46 of the folded portion of the first claw portion 44 is located radially outward from the outer edge of the flange 57, and the outer edge of the flange 57 comes into contact from below inside the apex 46 of the first claw portion 44, making it easy for the first claw portion 44 to bend.

[0027] 10(B), when the nut 55 is pushed in while pushing aside the first claw portion 44, the nut 55 is brought even closer to the mounting surface 39 of the support portion 35, and the flange 57 is hooked onto the second claw portion 47. At this time, guide surfaces 51 and 52 are formed on the first and second claw portions 44 and 47, and the guide surfaces 51 and 52 are inclined so that the distance between the opposing guide surfaces 51 and 52 narrows in the mounting direction (upward). As the outer edge of the flange 57 contacts the guide surfaces 51 and 52, the nut 55 is smoothly guided toward the mounting surface 39 along the inclination of the guide surfaces 51 and 52.

[0028] 10(C), when the nut 55 is pushed in while pushing aside the first claw portion 44, the flange 57 comes off the toe 45 of the first claw portion 44, and the nut 55 is pressed against the mounting surface 39 of the support part 35. The female thread 56 of the nut 55 enters the opening 41 of the mounting surface 39, and the flange 57 of the nut 55 fits inside the square frame-shaped fitting portion 38 of the support part 35. In addition, the first claw portion 44 elastically returns from its bent state, and the flange 57 is supported from below by the toes 45, 48 of the first and second claw portions 44, 47. In this way, the outward bending of the first claw portion 44 allows the nut 55 to be attached to the mounting surface 39 of the support part 35.

[0029] As shown in Figure 10(D), the fuel tank 25 is placed on the rear fender 13, and the fixing hole 27 of the flange 26 of the fuel tank 25 is aligned with the threaded hole 58 of the female screw 56. The bolt 29 is inserted from above the flange 26 of the fuel tank 25, and then tightened into the threaded hole 58 of the female screw 56. The flange 57 of the nut 55 is positioned in the fitting portion 38 of the support portion 35, preventing the nut 55 from rotating when the bolt 29 is tightened. Furthermore, because the support portion 35 is formed in an inverted concave shape in cross section, which increases its rigidity, the support portion 35 will not deform even if the bolt 29 is tightened too tightly.

[0030] In this case, the nut 55 can be attached to the support portion 35 with a single touch, facilitating the work of attaching the nut 55. The first and second claw portions 44, 47 prevent the nut 55 from falling off, and the fitting portion 38 restricts the rotation of the nut 55, eliminating the need to hold the nut 55 down with a tool or the like when tightening the bolt 29, facilitating the work of fastening the fuel tank 25. The flange 57 of the nut 55 covers the opening 41 and the notches 42, 43 (see Figure 7) in the mounting surface 39 from below, preventing foreign matter from entering the upper side of the rear fender 13 through the opening 41 and the notches 42, 43. The thread strength of the nut 55 is sufficient against the tightening torque, so there is no need to use a thread locking agent.

[0031] As described above, according to this embodiment, even if the nut 55 is pushed toward the support portion 35 from below the rear fender 13 and the flange 57 of the nut 55 is caught on the second claw 47 and then the flange 57 of the nut 55 comes into contact with the first claw 44, the first claw 44 bends, thereby allowing the nut 55 to be attached to the support portion 35. When the nut 55 is attached to the support portion 35, the fitting portion 38 positions the nut 55 so that it cannot rotate, and the first and second claws 44, 47 prevent the nut 55 from falling off. Therefore, the fuel tank 25 can be easily screwed onto the female thread 56 of the nut 55 exposed from the opening 41 of the support portion 35. Furthermore, because the opening 41 of the support portion 35 is covered from below by the flange 57, no gap is created when the nut 55 is attached to the support portion 35, and therefore, foreign matter such as mud or water does not get inside the rear fender 13.

[0032] In this embodiment, the support portion is provided with two claws, but the support portion may be provided with multiple claws. For example, the support portion may be provided with three or more claws. In this case, it is sufficient that at least one of the three or more claws is formed so as to bend when the flange comes into contact with the lower side of at least one of the three or more claws.

[0033] In addition, in this embodiment, the first claw portion is folded back in a U-shape and the second claw portion is not folded back, but both the first and second claw portions may be folded back in a U-shape.

[0034] In this embodiment, the nut is formed so that only the first claw bends and the second claw does not, but the first and second claws may be formed so that they bend when the flange of the nut comes into contact with them from below. In this case, when the outer edge of the flange comes into contact with the tips of the first and second claws from below, the first and second claws begin to bend outward, allowing movement in the installation direction of the nut.

[0035] In this embodiment, the outer edge of the nut flange is formed in a square shape, and the fitting portion is formed in a square frame shape, but the shapes of the flange and the fitting portion are not particularly limited as long as the flange can be positioned by the fitting portion. For example, the outer edge of the flange may be formed in a rectangular shape, and the fitting portion may be formed in a rectangular frame shape.

[0036] In addition, in this embodiment, the support portion is formed to have an inverted concave shape in cross section, but the cross-sectional shape of the support portion is not particularly limited. The rigidity of the support portion may be ensured by ribs or the like.

[0037] Although a fuel tank is used as an example of a vehicle part in this embodiment, the vehicle part may be any part that can be attached to the rear fender. For example, the vehicle part may be a battery case or a storage case.

[0038] Furthermore, the vehicle component holding structure is not limited to the illustrated saddle-ride type vehicle, and may be employed in other types of saddle-ride type vehicles. A saddle-ride type vehicle is not limited to all vehicles in which a rider straddles a seat, but also includes small scooter-type vehicles in which a rider does not straddle a seat.

[0039] As described above, the vehicle component (fuel tank 25) retention structure of this embodiment is a vehicle component retention structure formed in the rear fender (13), and includes a nut (55) having a flange (57) extending radially outward from a cylindrical female thread (56), and a support portion (35) that supports the vehicle component from below on the rear fender. The support portion is formed so that the nut can be attached from below the rear fender. The support portion is formed with an opening (41) for receiving the female thread, a fitting portion (38) that positions the flange, and multiple claws (first and second claws 44, 47) that latch the flange from below. When the flange contacts at least one of the multiple claws from below, the at least one claw bends, allowing the nut to be attached to the support portion. With this configuration, even if the nut is pushed toward the support portion from below the rear fender and the flange of the nut contacts at least one of the multiple claws, the claw bends, allowing the nut to be attached to the support portion. When the nut is attached to the support part, the fitting part positions the nut so that it cannot rotate, and the multiple claws prevent the nut from falling off. This allows vehicle components to be easily screwed onto the female thread of the nut exposed from the opening in the support part. Furthermore, the opening in the support part is covered from below by the flange, so there is no gap when the nut is attached to the support part, preventing foreign matter such as mud or water from getting inside the rear fender.

[0040] In the vehicle component holding structure of this embodiment, at least one claw portion extends downward from the underside of the support portion and then is folded back in a U-shape with the toe (45) facing upward, and the flange contacts the at least one claw portion from below, causing the claw portion to bend. With this configuration, the folded-back U-shape can impart flexibility to the at least one claw portion. The upward-pointing toe contacts the flange from below, stably latching the flange.

[0041] In the vehicle component holding structure of this embodiment, the apex (46) of the folded portion of at least one of the claws is located radially outward from the outer edge of the flange. With this configuration, the outer edge of the flange comes into contact with the tip side of the apex of at least one of the claws from below, making the claws more likely to bend.

[0042] In the vehicle component holding structure of this embodiment, the support portion is formed with an inverted concave cross section, with an upper wall (36) on which the nut is attached and side walls (37) surrounding the nut. With this configuration, the side walls of the support portion increase the rigidity around the nut, suppressing deformation of the support portion even when the vehicle component is tightly screwed into the female threads of the nut. In addition, because the side walls of the support portion narrow the space below the nut, foreign matter such as mud and water is less likely to adhere to the nut from below.

[0043] Although the present embodiment has been described, other embodiments may be made by combining the above-described embodiments and modifications in whole or in part.

[0044] Furthermore, the technology of the present invention is not limited to the above-described embodiments, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to technological advances or other derived technologies, it may be implemented using that method. Therefore, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of symbols]
