Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, when assembling a saddle-riding type vehicle, it is easier to improve the workability of the assembly work by assembling each part in a sub-assembled state. However, in the technique described in Patent Document 1, there is a problem that it is difficult to improve the workability because, for example, a rear winkler is attached after only fixing the rear fender to the seat frame. Even if the rear winkler is attached to the rear fender in advance, in the technique described in Patent Document 1, after engaging the engaging portion, it is necessary to lift the side with the heavy rear winkler, and there is a risk that the workability at the time of fastening deteriorates. This invention has been made in view of the above circumstances, and aims to provide a saddle-type vehicle that is easier to fasten and easier to assemble the rear fender and the surrounding area of ​​the rear fender to the vehicle frame. [Means for solving the problem]

[0005] A saddle-type vehicle comprises a rear frame and a rear fender structure supported by the rear frame, wherein the rear fender structure is provided with a taillight and a rear turn signal at its rear end and a front fastening portion at its front end that abuts from below a frame-side fastening portion provided on the rear frame, wherein the rear end of the rear frame is provided with a rear end stay that is provided such that its vertical width decreases towards the rear, and to which the rear fender structure is attached, and the rear fender structure is formed in a tunnel shape that opens forward between the front and rear portions and covers the rear end stay from above, below, left and right, and is formed such that the cross-sectional area of ​​the tunnel-shaped opening increases towards the front, and fastening portions are provided on both the rear end stay and the tunnel portion to which fastening members are fastened. [Effects of the Invention]

[0006] This allows for improved workability during fastening and provides a saddle-type vehicle in which the rear fender and surrounding areas of the rear fender can be easily assembled to the vehicle frame. [Brief explanation of the drawing]

[0028] Figure 11 is a perspective view of the rear fender support 90. Figure 12 is a left side view of the rear fender support 90. Figure 13 is a top view of the rear fender support 90. Figure 14 is a front view of the rear fender support 90. The rear fender support portion 90 is made of metal. The rear fender support portion 90 extends in the front-rear direction. The rear fender support portion 90 is curved in an arc along the rear wheel 15. The rear fender support portion 90 has a bottom portion 91 that has thickness in the vertical direction, and side wall portions 92 that rise upward from both the left and right ends of the bottom portion 91.

[0029] A bulging portion 93 is formed in the center of the bottom portion 91 in the left-right direction, bulging upward. Therefore, both the left and right ends of the bottom portion 91 are recessed relative to the bulging portion 93. In other words, a recess 94 extending in the front-rear direction is formed in the bottom portion 91 by the bulging portion 93 and the side wall portion 92.

[0030] A bulging front end 95 is formed at the front end of the bulging portion 93. The amount of bulging of the bulging front end 95 decreases as it extends forward. In other words, the bulging front end 95 is inclined to approach the bottom surface portion 91 as it extends forward. In this embodiment, the bulging front end 95 is inclined downward as it extends forward. A fixing hole (second fastening portion, fastening portion) 95a is formed in the bulging front end 95, penetrating in the thickness direction. Therefore, the fixing hole 95a penetrates upwards towards the front.

[0031] A fixing hole portion 96 is formed at the rear of the bulging portion 93. A unit fastening portion 97 is formed behind the fixing hole portion 96. Plate holder fixing portions 98 are formed on both the left and right sides of the unit fastening portion 97, recessed upward and rearward from the lower surface. The plate holder fixing portions 98 are formed behind the unit fastening portion 97. The plate holder fixing portions 98 are formed behind the recess 94. A plate holder fixing hole 98a is formed in the plate holder fixing portion 98, extending perpendicularly to the upper surface of the plate holder fixing portion 98.

[0032] A bridge section 99, which is roughly inverted U-shaped in a front view, is provided at the front end of the bottom section 91. The bridge section 99 is a strip-shaped plate extending in the vehicle width direction. The bridge section 99 is provided so as to cover the bulging front end 95 from above. In detail, the bridge section 99 has a bridge upper surface section 99a that extends in the left-right direction and overlaps the bulging front end 95, and a pair of left and right bridge legs 99b that extend downward from both the left and right ends of the bridge upper surface section 99a. The bridge legs 99b are fixed to the inner surface of the side wall section 92. The enclosed shape of the bridge section 99 and the bottom section 91 forms a tunnel shape that penetrates in the front-rear direction. The bridge section 99 and the front end of the bottom section 91 constitute the tunnel section 100 of this embodiment.

[0033] In the tunnel section 100, the opening area of ​​the tunnel section 100 expands as it proceeds forward due to the bridge upper surface 99a of the bridge section 99 and the bulging front end 95 of the bottom surface 91. Fixing holes (first fastening part, fastening part) 99c that penetrate in the thickness direction are formed in the bridge upper surface 99a. That is, the fixing holes 99c penetrate in the vertical direction. In this embodiment, the fixing holes 99c are formed in front of the fixing holes 95a of the bulging front end 95 in a plan view.

[0034] In this embodiment, the first fastening portion 99c and the second fastening portion 95a provided on the rear fender support portion 90 are positioned to form the vertices of a triangle when viewed from the front of the vehicle body (see Figure 14). Furthermore, in this embodiment, the first fastening portion 99c and the second fastening portion 95a provided on the rear fender support portion 90 are positioned to form triangular vertices in a plan view of the vehicle body (see Figure 13).

[0035] As shown in Figures 7 to 10, the rear fender support portion 90 is covered from above by the rear fender 70. The rear fender 70 is made of resin or metal. The rear fender 70 is longer in the front-rear direction than the rear fender support portion 90. The rear fender 70 is curved in an arc shape when viewed from the side of the vehicle.

[0036] The rear fender 70 has a vertically thickened upper surface portion 71 that bulges upward. In plan view, the upper surface portion 71 overlaps with the rear fender support portion 90. A pair of left and right fixing holes 71a are formed at the front end of the upper surface portion 71. The fixing holes 71a are formed in accordance with the positions of the fixing holes 99c of the bridge portion 99 of the rear fender support portion 90.

[0037] A unit mounting opening (not shown) is formed at the rear of the upper surface portion 71 (the rear of the rear fender 27). This unit mounting opening is an opening that connects the upper surface portion 71 in the vertical direction, exposing the fixing hole portion 96 and the unit fastening portion 97 of the rear fender support portion 90 above the upper surface portion 71. That is, the base member 52 of the rear light unit 51 is inserted into the unit mounting opening. The base member 52 of the rear light unit 51 is then fixed using the fixing hole portion 96 and the unit fastening portion 97 of the rear fender support portion 90. The base member 52 of the rear light unit 51 is attached so as to cover the unit mounting opening. As a result, the upper surface portion 71 of the rear fender 70 is sandwiched between the rear light unit 51 and the rear fender support portion 90. This results in the rear fender 70 being supported by the rear fender support portion 90.

[0038] On both the left and right sides of the upper surface portion 71, side wall portions 72 are formed that curve downward from both ends of the upper surface portion 71. The side wall portions 72 extend in the front-rear direction. The side wall portions 72 extend further forward than the upper surface portion 71. An engaging projection 72a (see Figure 9) is formed on the inner front end of the side wall portion 72, projecting inward in the vehicle width direction. Above the engaging projection 72a, a connecting portion 73 is formed that connects the upper edges of the front ends of the left and right pair of side wall portions 72.

[0039] The connecting portion 73 is plate-shaped with thickness in the vertical direction. The connecting portion 73 has a pair of left and right seating protrusions (front fastening portions) 74. The seating protrusions 74 have a lower surface that is concave upwards and convex upwards. The upper surface of the seating protrusions 74 is formed flat. The upper surface of the seating protrusions 74 slopes downwards as it extends forward. Holes are formed in the seating protrusions 74 that penetrate in the thickness direction. To the left of the seat surface protrusion 74 on the left side, a flat harness guide 73a (see Figure 8) is formed that protrudes upward.

[0040] The rear fender 70 has an opening 75 that opens vertically, formed by the enclosed shape of the upper surface portion 71, a pair of left and right side wall portions 72, and a connecting portion 73. Here, the front end of the upper surface portion 71 is connected to the pair of left and right side wall portions 72 to form a front portion 71c that narrows the opening 75. The front portion 71c curves inward in the vehicle width direction as it moves towards the rear.

[0041] The opening 75 has a front opening 75a whose width is defined by a pair of left and right side wall portions 72, and a rear opening 75b whose width is defined by a pair of left and right front portions 71c. The rear opening 75b has a smaller width than the front opening 75a. The rear opening 75b has an opening shape that opens in the front-rear direction. The tunnel portion 100 of the rear fender support portion 90 is connected to the rear of the rear opening 75b.

[0042] The opening 75 is closed from below by the front rear fender 60. The front rear fender 60 is made of resin. The front rear fender 60 is curved in an arc shape. The front rear fender 60 is roughly shaped to extend forward from the top of the rear fender 27.

[0043] The front rear fender 60 has an upper surface portion 61 that has thickness in the vertical direction, and side wall portions 62 that bend downward from the left and right sides of the upper surface portion 61. A connecting portion 61a (see Figure 9) is formed at the rear end of the upper surface portion 61. The connecting portion 61a is positioned above the bottom surface portion 91 of the rear fender support portion 90 and overlaps the rear fender support portion 90 when viewed from below.

[0044] An outer casing 63 that protrudes upward is formed on the upper surface of the upper surface portion 61. The outer casing 63 protrudes upward through an opening 75 formed in the rear fender 70. More specifically, the outer casing 63 is narrower in width than the front opening portion 75a and protrudes upward from the side portion of the rear fender 70 through the front opening portion 75a. Inside the outer casing 63, a flat surface 64 for arranging electrical components is formed.

[0045] An electrical unit 57 is positioned on the electrical unit placement surface 64. The electrical unit 57 is, for example, an ETC (Electronic Toll Collection System) unit. The ETC unit performs electronic payment by transmitting and receiving data with ETC equipment at toll booths.

[0046] An open connector connection port 63a is formed at the front end of the outer casing 63. A fastening portion 65 having thickness in the vertical direction is supported at the rear end of the outer casing 63. The fastening portion 65 is provided in correspondence with the second rear end stay 44. A harness housing rib 66 extending in the front-rear direction is formed on the outer side of the outer casing 63 in the vehicle width direction. The harness housing rib 66 protrudes upward from the opening 75. The harness housing rib 66, the outer casing 63, and the upper surface 61 form a groove shape extending in the front-rear direction.

[0047] A pair of left and right engaging claws 67 are formed in front of the outer casing 63, spaced at a predetermined interval. The engaging claws 67 abut against the connection portion 73 of the rear fender 70 from the front and above.

[0048] As shown in Figure 9, a pair of fastening portions 68 are formed on the lower surface of the upper portion 61. The fastening portions 68 are formed behind the engaging claws 67. The fastening portions 68 enter from below into and are held by the seating surface protrusion 74 of the rear fender 70. Corresponding to the left-right outer side of the fastening portion 68, a notch 62a is formed in the side wall portion 62 that engages with the engaging projection 72a of the rear fender 70.

[0049] The front rear fender 60 is assembled to the rear fender support 90 and the rear rear fender 70 by the connection portion 61a, the engaging claw 67, and the notch 62a.

[0050] A license plate holder 80 is fixed to the fastening portion of the rear fender support portion 90. The license plate holder 80 is made of resin. The license plate holder 80 has an upper fixing portion 81 and a plate-shaped downward extension portion 82 that extends downward from the fixing portion 81.

[0051] Multiple fastening portions 81a are formed in the fixing portion 81. Fastening members are inserted through the multiple fastening portions 81a from the front and fixed to the plate holder fixing portion 98 of the rear fender support portion 90. A license plate (not shown) is supported on the outer surface, i.e., the rear surface, of the downward extension portion 82.

[0052] As shown in Figures 7, 8, and 10, the harness 53a for the taillight 53 and the harness 54a for the rear turn signal 54 are housed in the left recess 94 at the bottom surface 91 of the rear fender support 90 and routed forward along the left recess 94. The harnesses 53a and 54a routed forward pass through the tunnel section 100 and the rear part 75b of the opening 75 and are routed forward. The harnesses 53a and 54a routed forward are then housed between the outer casing 63 of the rear fender support 90 and the harness housing rib 66, and are hooked onto the harness guide 73a and routed forward.

[0053] Figure 15 is an explanatory diagram illustrating the process of assembling the rear fender structure 50 to the rear frame 20. The rear fender structure 50 is positioned slightly downwards at the front. The rear fender structure 50 is then moved from the rear toward the rear end stay 43 so that the rear end stay 43 enters the rear opening 75b of the opening 75 (see arrow in Figure 15). As a result, the rear end stay 43 enters the tunnel section 100 from the rear opening 75b, and the seating surface protrusion 74 of the connecting portion 73 at the front of the rear fender structure 50 moves below the front fender stay 42. Here, the rear end stay 43 has a tapered shape that faces rearward. On the other hand, the tunnel section 100 has an opening cross-sectional area that increases towards the front, so the rear end stay 43 can easily enter the tunnel section 100.

[0054] When the rear end stay 43 enters the tunnel section 100, the inclined surface portion 43a2 comes into contact with the bulging front end portion 95. At this time, in the tunnel section 100, the bulging front end portion 95 guides the rear end stay 43 upward, and the flat portion 43a1 of the rear end stay 43 comes into contact with the lower surface of the bridge portion 99 of the tunnel section 100. Therefore, the rear end stay 43 is easily positioned while sandwiched between the bridge portion 99 of the tunnel section 100 and the bulging front end portion 95 of the tunnel section 100.

[0055] At this time, since the rear end stay 43 has entered the tunnel section 100, even if the worker releases their hand from the rear fender structure 50, the rear fender structure 50 will remain suspended.

[0056] Here, in the rear fender structure 50, the rear light unit 51 is supported on the rearward side of the tunnel section 100. In other words, the center of gravity of the rear fender structure 50 is set behind the tunnel section 100. Therefore, when hanging, the tunnel section 100 acts as a fulcrum, and the rear part of the rear fender structure 50 rotates downward. Consequently, in the rear fender structure 50, the front part in front of the tunnel section 100 rotates upward, and the seating surface protrusion 74 easily comes into contact with the front fender stay 42 from below. In other words, by utilizing the moment effect due to the center of gravity, it becomes easier for the worker to control the posture of the rear fender structure 50 when fastening.

[0057] Therefore, the worker can fasten the rear fender structure 50 without having to support it. In other words, for example, the worker can easily fasten it with both hands.

[0058] When assembling the rear fender structure 50 to the rear frame 20, a gate-shaped seat stay 110 is positioned on the upper surface 71 of the rear fender 70. Then, bolts (first fastening member, fastening member) extending in the vertical direction are inserted from above into a pair of left and right insertion holes (not shown) provided in the seat stay 110. The bolts 121 are fastened to the first fastening portion 43b1 of the rear end stay 43, with the bolts 121 passing through the seat stay 110, the upper surface 71 of the rear fender 70, and the tunnel portion 100 of the rear fender support portion 90.

[0059] Furthermore, bolts (second fastening member, fastening member) are inserted from the rear lower part of the rear fender support portion 90. Bolt 122 is fastened to the inclined surface portion 43a2 of the rear end stay 43. As a result, the rear fender structure 50 is fastened to the rear end stay 43.

[0060] Furthermore, a bolt (third fastening member) 123 is fastened to the rear fender structure 50 from above the second rear end stay 44. This fixes the front rear fender 60 to the second rear end stay 44.

[0061] Furthermore, in the front fender stay 42, a bolt (fourth fastening member) 124 is inserted from the front and above through the fixing hole 42c, passes through the seating surface protrusion 74 of the rear fender 70, and is fastened to the fastening portion 68 of the front rear fender 60. Thus, the front rear fender 60 and the rear rear fender 70 are fastened to the front fender stay 42. In this way, the rear fender structure 50 is assembled to the rear frame 20. The seat 17 is then assembled using the seat stay 110 and seat support 45, and the upper part of the rear fender structure 50 is covered by the seat 17.
