Summary of the utility model

Problems to be solved by the utility model

However, the rear fender has a function of suppressing scattering of muddy water or the like rolled up by the rear wheel. On the other hand, it is preferable that the direction of the wind flow can be adjusted by a rib or the like of the rear fender (fender). That is, it is preferable that the scattering of muddy water or the like of the mud shield be suppressed and the direction of the flow of the wind be adjusted efficiently.

Accordingly, an object of the present utility model is to efficiently suppress scattering of muddy water or the like in a mud cover and to adjust the direction of the flow of wind in a saddle-ride type vehicle.

Means for solving the problems

As a solution to the above problem, one aspect of the present utility model is a saddle-ride type vehicle including a mud cover (31) covering a wheel (4) from above, wherein the mud cover (31) includes: a pair of side walls (31 m) that extend in the vehicle longitudinal direction at both vehicle width direction side portions; a plurality of lateral ribs (31 n1, 31n2, 31n3, 31n 4) extending in the vehicle width direction between the pair of side walls (31 m); and a base portion (31 k) that covers the pair of side walls (31 m) and the installation region (R1) of the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) from above, projects the pair of side walls (31 m) and the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) on the lower surface (31 p) side, the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) are arranged in the vehicle front-rear direction, a gap (61) in the vehicle width direction is provided between the pair of side walls (31 m) and the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) at the vehicle width direction end portions, and the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) extend obliquely downward and forward from the lower surface (31 p) of the base portion (31 k), and the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) are provided independently from the lateral rib portions (31 n1, 31n2, 31n 4) and the lateral rib portions (31 w ) extend from the main body (31 w) and the lateral rib portions (31 w) are provided independently from the lateral rib portions (31 n3, 31n 4).

According to this structure, the mud flap can be reinforced by the pair of side walls and the cross rib. The base portion covers and closes the installation regions of the pair of side walls and the lateral rib, and the pair of side walls and the lateral rib protrude from the lower surface of the base portion, so that the following effects are obtained. That is, muddy water or the like caught by the wheels can be made difficult to reach above the mud guard. Further, the side wall and the lateral rib portion can flow outward in the vehicle width direction in the wind direction rolled up from the wheel to the inside of the fender. Therefore, the wind flowing from the front of the vehicle can be suppressed from colliding with the wind curled up by the wheels.

In addition, by the gap between the side wall and the lateral rib, muddy water or the like can be easily discharged to the front of the fender through the gap. That is, if muddy water or the like falls down in the middle of the side wall, the muddy water or the like may scatter outside the fender. In contrast, muddy water or the like is easily discharged to the front of the fender by passing through the muddy water or the like, and scattering of the muddy water or the like to the outside of the fender can be suppressed.

Further, the vertical thickness of the mud cover can be suppressed, and the influence on the vehicle appearance can be suppressed, as compared with the case where the lateral rib portion extends vertically downward. In addition, the transverse rib inclined obliquely downward and forward above the wheel is more likely to flow muddy water or the like adhering to the transverse rib outward in the vehicle width direction by the forward inclination than in the case of extending vertically. Therefore, muddy water or the like can be easily transported from the gap between the side wall and the lateral rib portion.

Further, the lateral rib is constituted by the plate-shaped lateral rib main body and the support portion, so that the weight of the mud cover can be suppressed. That is, the weight of the transverse rib portion can be suppressed as compared with the case where the transverse rib portion is formed in a solid block shape. In addition, a cross rib of a predetermined angle can be formed.

In the above aspect, the distance in the vehicle width direction between the pair of side walls (31 m) may be increased as the distance is increased toward the front side in the vehicle longitudinal direction, and the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) may be arranged in the vehicle longitudinal direction, and the width in the vehicle width direction may be increased as the distance between the plurality of lateral rib portions (31 n1, 31n2, 31n3, 31n 4) is increased toward the front side in the vehicle longitudinal direction.

According to this configuration, the width of the gap between the pair of side walls of the flow path of the wind in which the wheel is caught increases toward the front side of the wheel (toward the downstream side in the wheel rotation direction). Therefore, the flow of wind caught by the wheels can easily flow outward in the vehicle width direction. Further, since the base portion on the front side of the wheel is expanded, muddy water and the like are easily received, and scattering of muddy water and the like can be effectively suppressed.

In the above aspect, the saddle-ride type vehicle may further include a split cover (38) that is formed in a split manner with respect to the base (31 k) and covers an upper surface (31 v) of the base (31 k).

According to this structure, even if an air hole is generated in the upper surface of the base portion due to the formation of the side wall, the lateral rib, and the like, the air hole can be hidden by the separate cover. Therefore, the appearance of the mud cover can be improved.

In the above aspect, electrical components (52, 53) may be supported by at least one of the mud guard (31) and the separate cover (38).

With this configuration, the wiring reaching the electrical component can be hidden between the mud cover and the separate cover. Therefore, the wiring can be protected, and the appearance of the mud cover can be improved.

In the above aspect, the pair of side walls (31 m) and the lateral rib portions (31 n1, 31n2, 31n3, 31n 4) of the mud cover (31) may be provided above the air cleaner (109) having the air inlet (109 a).

According to this structure, the wind flowing from the front of the vehicle can be prevented from colliding with the wind curled up by the wheels. In addition, by this effect, the influence of the amount of air taken into the air cleaner can be suppressed. In addition, if the structure has a gap between the side wall of the mud guard and the cross rib, the following effects are exhibited. That is, muddy water is easily transported to the front of the fender, and the muddy water and the like are prevented from falling down in the middle of the side wall. Therefore, muddy water or the like falling in the middle can be suppressed from reaching the air inlet of the air cleaner.

Effects of the utility model

According to the present utility model, in a saddle-ride type vehicle provided with a mud cover covering a wheel from above, the mud cover can be reinforced by the side walls and the lateral rib portions. Further, scattering of muddy water or the like rolled up by the wheels can be suppressed by the side walls and the lateral ribs. In addition, the direction of the wind flowing in the rear side of the fender can be adjusted.

Rear end portions of the left and right rear seat frames 14b are connected by a cross pipe 71 extending in the vehicle width direction. The fender bracket 48 is attached to the cross pipe 71. The fender bracket 48 includes an upper bracket 48a extending upward from the cross pipe 71 and a rear bracket 48b extending rearward from a lower portion of the upper bracket 48 a.

A seat lock device 73 for locking the seat 22 is provided on the upper bracket 48 a.

The bottom cover 42 is fixed to the lower bracket 48b by being fastened and connected appropriately. The tail lamp 27 is supported at the rear of the front rising portion 42c of the under cover 42.

A license lamp 52 is mounted at the rear end of the bottom cover 42. The wiring 75 of the license lamp 52 passes through the space 55 provided in the middle portion of the bottom cover 42 in the front-rear direction. Wiring (not shown) to the left-right rear direction indicator lamp 53 also passes through the space 55. An inner fender 77 covering the front portion of the rear wheel 4 is connected to the front of the rear fender 31.

The lower surface 31p of the front cover 31a of the rear fender 31 is disposed substantially horizontally. The rib bodies 31w2, 31w3, 31w4 of the plurality of rib portions 31n2, 31n3, 31n4 are inclined at an angle θ toward obliquely front lower sides with respect to the front lower surface 31 q. For example, the angle θ is smaller than 45 °. The cross rib 31n1 on the concave lower surface 31s is inclined as follows in a side view of the vehicle. That is, the cross rib 31n1 is inclined obliquely downward and forward at an angle θ with respect to a tangent line of the concave lower surface 31s at the base end position of the cross rib body 31w1, for example. The upper surface 31v of the hood wall 31k provided in the installation region R1 of the rear fender 31 is covered with the hood assembly 38.

Next, the operation of the rear fender 31 will be described with reference to fig. 4 and 6.

During running of the motorcycle 1, wind caught by the rotation of the rear wheels 4 and mud and water (hereinafter, referred to as "muddy water or the like") caught by the road surface flow as indicated by an arrow a in fig. 6. That is, the wind, muddy water, and the like first flow toward the rear inclined hood 31 b. The wind, muddy water, etc. contacting the rear lower surface 31r then flows obliquely forward and upward along the rear lower surface 31r as indicated by an arrow B in fig. 6.

The wind, muddy water, and the like then contact the cross rib body 31w1 of the cross rib portion 31n1 on the vehicle width direction inner side of the rear fender 31. As shown by arrow C in fig. 6, muddy water or the like contacting the cross rib 31n1 falls down while changing the direction to the obliquely lower front side along the inclination of the cross rib body 31w 1. Muddy water or the like which is rolled up by the rear wheel 4 and directly contacts the cross rib portions 31n1, 31n2, 31n3, 31n4 also falls down along the cross rib main bodies 31w1, 31w2, 31w3, 31w4 while changing the direction to the obliquely lower front as indicated by an arrow C, D, E, F in fig. 6.

The space (tire cover) below the rear fender 31 generates a flow of air caught by the rotation of the rear wheel 4. The flow of air (wind) is appropriately disturbed by contact with the rib bodies 31w1, 31w2, 31w3, and 31w 4. This provides the following effects as compared with the case where the lower surface of the rear fender 31 is flat. That is, the flow velocity of wind involved in the rotation of the rear wheel 4 is suppressed, and the pressure rise on the front side of the wheel is suppressed. Therefore, the air resistance and the lift force on the front side of the wheel can be suppressed. Further, scattering of muddy water or the like to the outside in the vehicle width direction or the like can be suppressed.

In the gaps 61 on both sides of the lateral rib 31n1, a part of muddy water or the like passes through the one-side passage 62 and the other-side passage 63 together with wind generated by the rotation of the rear wheel 4 (see fig. 4). The wind, muddy water, etc. tend to weaken in the middle. The wind, muddy water, etc. fall from the upper part of the rear fender 31 or fall while being caught by the inner fender 77 in front of the rear fender 31 as indicated by an arrow G in fig. 6. At this time, the wind, muddy water, and the like move together in the one-side passage 62 and the other-side passage 63. Therefore, muddy water or the like can be allowed to fall in the tire cover without scattering around.

The fastening portions 31h are disposed in the middle of the one-side passage 62 and the other-side passage 63, respectively. Each fastening portion 31h is formed in a concave shape to suppress the protrusion of the bolt or the like. Therefore, the flow of wind, muddy water, and the like in the one-side passage 62 and the other-side passage 63 is not hindered.

The interval in the vehicle width direction between the left and right side bracket portions 31m gradually becomes wider as it goes from the rear tilt cover 31b toward the front cover 31 a. Therefore, when wind flows forward between the left and right side frame portions 31m, the flow velocity of the wind gradually becomes slow, and the flow of the wind is easily disturbed.

The width of the plurality of cross ribs 31n1, 31n2, 31n3, 31n4 in the vehicle width direction increases toward the front side. Therefore, the flow of wind is more easily disturbed, and muddy water and the like are easily held. That is, the wind that spreads in the vehicle width direction between the left and right side frames 31m contacts the cross ribs 31n1, 31n2, 31n3, 31n4 that also spreads in the vehicle width direction over a wide range. Thus, the flow of wind is more likely to be disturbed. The muddy water or the like rolled up by the rear wheel 4 is well received by the lateral ribs 31n1, 31n2, 31n3, 31n4 having gradually wider widths. Therefore, scattering of muddy water or the like can be effectively suppressed.

As described above, the saddle-ride type vehicle in the above embodiment is the motorcycle 1 provided with the rear fender 31 covering the rear wheel 4 from above. The rear fender 31 includes: a pair of side frames 31m extending in the vehicle front-rear direction at both vehicle width direction side portions; cross ribs 31n1, 31n2, 31n3, 31n4 extending in the vehicle width direction between the pair of side frames 31m; and a cover wall 31k covering the installation region R1 of the pair of side frame portions 31m and the lateral rib portions 31n1, 31n2, 31n3, 31n4 from above. The cover wall 31k projects the pair of side frame portions 31m and the lateral rib portions 31n1, 31n2, 31n3, 31n4 toward the lower surface 31 p.

According to this structure, the rear fender 31 can be reinforced by the pair of side brackets 31m and the cross ribs 31n1, 31n2, 31n3, 31n 4. The cover wall 31k covers and closes the installation region R1 of the pair of side frame portions 31m and the lateral rib portions 31n1, 31n2, 31n3, 31n 4. The pair of side bracket portions 31m and the cross rib portions 31n1, 31n2, 31n3, 31n4 are projected on the lower surface 31p of the cover wall 31 k. This achieves the following effects. That is, muddy water or the like which is rolled up by the rear wheels 4 can be made difficult to reach above the rear fender 31. Further, the pair of side brackets 31m and the cross ribs 31n1, 31n2, 31n3, 31n4 can suppress scattering of muddy water or the like to the vehicle width direction outer side and the front side (the wheel rotation direction downstream side).

In this way, the side bracket portion 31m and the cross rib portions 31n1, 31n2, 31n3, 31n4 provide both reinforcement of the rear fender 31 and suppression of scattering of muddy water or the like. This can effectively reinforce the rear fender 31 and suppress scattering of muddy water or the like.

In the above-described straddle-type vehicle, the vehicle width direction gap 61 is provided between the pair of side frames 31m and the vehicle width direction ends of the lateral ribs 31n1, 31n2, 31n3, 31n4, respectively. Thus, the flow of wind caught by the rear wheel 4 is appropriately disturbed by the cross ribs 31n1, 31n2, 31n3, 31n 4. Therefore, the pressure rise on the front side of the rear wheel 4 can be suppressed, and the air resistance and the lift force can be suppressed. In addition, a proper amount of wind flows through the gaps 61 between the side bracket portions 31m and the cross rib portions 31n1, 31n2, 31n3, 31n 4. By the flow of the wind, muddy water or the like can be discharged to the front side along the side bracket portion 31 m.

In this way, the cross ribs 31n1, 31n2, 31n3, 31n4 can suppress the influence of the air flow around the rear wheel 4. In addition, the muddy water or the like can be easily discharged through the gaps 61 between the side bracket portions 31m and the cross rib portions 31n1, 31n2, 31n3, 31n 4.

In the saddle-ride type vehicle, the distance in the vehicle width direction between the pair of side frames 31m increases as the distance increases toward the front side in the vehicle longitudinal direction. The plurality of cross ribs 31n1, 31n2, 31n3, 31n4 are arranged in the vehicle longitudinal direction. The width in the vehicle width direction increases as the plurality of cross ribs 31n1, 31n2, 31n3, 31n4 are located further toward the front side in the vehicle longitudinal direction. The following effects are obtained by widening the width of the space between the pair of side frame portions 31m that become the flow path of the wind that the rear wheel 4 winds toward the front side (the downstream side in the wheel rotation direction) of the rear wheel 4. That is, the flow of wind caught by the rear wheel 4 is easily disturbed, and the pressure rise in the front side of the rear wheel 4 can be effectively suppressed. Further, since the cover wall 31k on the front side of the rear wheel 4 is expanded, muddy water or the like is easily received, and scattering of muddy water or the like can be effectively suppressed.

In the saddle-ride type vehicle, the cross rib portions 31n1, 31n2, 31n3, 31n4 (specifically, the cross rib bodies 31w1, 31w2, 31w3, 31w 4) extend obliquely downward and forward from the lower surface 31p of the cover wall 31 k. This has the following effects as compared with the case where the lateral rib portion extends vertically downward. That is, the vertical thickness of the rear fender 31 can be suppressed, and the influence on the vehicle appearance can be suppressed. The cross ribs 31n1, 31n2, 31n3, 31n4 inclined obliquely downward and forward above the rear wheel 4 are likely to collide with wind, muddy water, or the like, which is entrained and rotated by the rear wheel 4. Therefore, the flow of wind is easily disturbed, and the muddy water is easily received.

The saddle-ride type vehicle includes a cover assembly 38 that is separate from the cover wall 31k and covers the upper surface 31v of the cover wall 31 k. This can improve the appearance of the rear fender 31. That is, even if air holes are generated in the upper surface 31v of the cover wall 31k by the formation of the side bracket portion 31m and the cross rib portions 31n1, 31n2, 31n3, 31n4, etc., the air holes can be hidden by the separate cover assembly 38.

In the saddle-ride type vehicle, at least one of the rear fender 31 and the cover assembly 38 supports the rear winkers 53 and the license lamps 52. Thus, the wiring 75 reaching the license lamp 52 and the rear direction indicator lamp 53 can be hidden between the rear fender 31 and the hood assembly 38. Therefore, the wiring 75 can be protected, and the external appearance of the rear fender 31 can be improved.

In the above-described straddle-type vehicle, the cross rib portions 31n1, 31n2, 31n3, 31n4 include plate-shaped cross rib bodies 31w1, 31w2, 31w3, 31w4 extending in the vehicle width direction, and leg portions 31y extending from the cross rib bodies 31w1, 31w2, 31w3, 31w4 toward the lower surface 31p of the hood wall 31 k. The cross rib portions 31n1, 31n2, 31n3, 31n4 are constituted by plate-shaped cross rib bodies 31w1, 31w2, 31w3, 31w4 and leg portions 31y. Therefore, the following effects are achieved compared to the case where the lateral rib portions 31n1, 31n2, 31n3, 31n4 are formed in a solid block shape. That is, the weight of the lateral ribs 31n1, 31n2, 31n3, 31n4 can be suppressed. The cross ribs 31n1, 31n2, 31n3, 31n4 can be formed at a predetermined angle. This can suppress the weight of the rear fender 31 and can easily hold down wind, muddy water, and the like which are caught and rotated by the rear wheel.

< second embodiment >

Next, a second embodiment of the present utility model will be described with reference to fig. 2 to 6 and fig. 7.

This embodiment is different from the first embodiment in that the rear fender 31 is applied to the motorcycle 101 including the swing type power unit 105. The same reference numerals are given to the other components similar to those of the above embodiment, and detailed description thereof will be omitted.

< vehicle entirety >

Fig. 7 shows a scooter type motor bicycle (saddle-ride type vehicle) 101 as an example of the vehicle of the second embodiment. The motorcycle 101 includes a front wheel 103 as a steering wheel and a rear wheel 104 as a driving wheel. The front wheel 103 is supported by a front fork 103a, and can be steered by a steering handle 102. The rear wheel 104 is supported by a swing type power unit 105, and can be driven by the power unit 105. In the figure, reference numeral 104a denotes a rear cushion for supporting the rear end portion of the power unit 105.

A steering system member including a steering handle 102, a front fork 103a, and a front wheel 103 is supported in a steerable manner by a head pipe 121a at the front end portion of the frame 121. The front portion of the power unit 105 is supported on the lower portion of the frame 121 so as to be capable of swinging up and down.

The frame 121 includes: a head pipe 121a; a down frame 121b extending downward and rearward from the head pipe 121a; a lower frame 121c extending rearward from a lower end portion of the lower frame 121b; a rear frame 121d extending rearward and upward from a rear end portion of the lower frame 121c; and a seat frame 121e supported from below by the rear frame 121 d. The periphery of the frame 121 of the motorcycle 101 is covered with a body cover 122. The rear fender 31 similar to the first embodiment is provided at the rear end portion of the body cover 122.

A bottom pedal 106 for putting the foot of the driver is provided between the front wheel 103 and the rear wheel 104. For example, the bottom pedals 106 are provided in a pair of left and right. A central passage 107 is provided between the left and right bottom pedals 106. A front vehicle body 114 is provided in front of the bottom step 106. A rear vehicle body 115 is provided behind the bottom step 106. Between the front body 114 and the rear body 115, a space above the bottom pedal 106 becomes a riding space when the driver straddles the body. A steering handle 102 is disposed above the front vehicle body 114. A seat 108 on which an occupant sits is arranged above the rear vehicle body 115.

The power unit 105 includes: an engine 105a as an internal combustion engine; and a transmission (e.g., belt type continuously variable transmission) 105b that transmits the driving force generated by the engine 105a to the rear wheels 104. The transmission 105b includes a transmission case 105c. The transmission case 105c extends rearward from one side (left side) of the crankcase of the engine 105a in the vehicle width direction (left-right direction). An air cleaner 109 of an engine intake system is disposed above the transmission case 105c. The air cleaner 109 is disposed so that the rear portion overlaps the front upper portion of the rear wheel 104 in a side view of the vehicle. The air cleaner 109 is disposed below and in front of the rear fender 31. The air cleaner 109 includes an intake port 109a through which outside air is taken in.

Referring to fig. 4 and 6, the motor bicycle 101 also functions in the running process as in the first embodiment. That is, wind caught by the rotation of the rear wheel 104, muddy water caught by the road surface, and the like come into contact with the cross rib bodies 31w1, 31w2, 31w3, and 31w4, and change the direction to the obliquely lower front side, and fall. The air inlet 109a of the air cleaner 109 opens toward the rear of the vehicle in a region overlapping the disk brake of the rear wheel 104 in a side view of the vehicle, for example. The air inlet 109a is disposed inside the outer cover. When muddy water or the like falls down in the middle of the side bracket portion 31m, the muddy water or the like may reach the air inlet 109a.

The space (tire cover) below the rear fender 31 generates a flow (wind) of air caught by the rotation of the rear wheel 104. The wind contacts the rib bodies 31w1, 31w2, 31w3, and 31w4 and flows obliquely downward and forward. Alternatively, the wind flows outward in the vehicle width direction along the cross rib main bodies 31w1, 31w2, 31w3, 31w 4. Therefore, the wind reaching the front of the fender (the front upper side of the rear wheel 104) is reduced.

Running wind from the front of the vehicle intrudes into the tire case. The air inlet 109a of the air cleaner 109 is configured to facilitate intake of the traveling wind in the tire case. When wind involved in the rear wheels 104 collides with traveling wind, the intake air amount of the air cleaner 109 may be affected. Therefore, the following effects are achieved by reducing wind from reaching the front of the fender by the cross rib bodies 31w1, 31w2, 31w3, 31w 4. That is, the influence of the intake air amount of the air cleaner 109 can be suppressed. In addition, the intrusion of muddy water or the like flowing together with the wind into the air inlet 109a can be suppressed.

As described above, the saddle-ride type vehicle (motorcycle 101) of the second embodiment also includes the rear fender 31 similar to the first embodiment. This makes it difficult for muddy water or the like caught by the rear wheel 104 to reach above the rear fender 31. The side bracket portion 31m and the cross rib portions 31n1, 31n2, 31n3, 31n4 enable the wind direction rolled up from the rear wheel 104 toward the fender inner side (lower surface side) to flow outward in the vehicle width direction. Therefore, the wind flowing from the front of the vehicle can be suppressed from colliding with the wind curled up by the rear wheels 104.

In the saddle-ride type vehicle according to the second embodiment, a gap 61 in the vehicle width direction is provided between the pair of side frames 31m and the vehicle width direction ends of the lateral ribs 31n1, 31n2, 31n3, 31n4, respectively. This makes it easy to discharge muddy water or the like to the front of the fender through the gap. That is, if the muddy water or the like falls down in the middle of the side stand portion 31m, the muddy water or the like may scatter outside the fender. In contrast, the muddy water or the like is easily discharged to the front of the fender after passing through, and scattering of the muddy water or the like to the outside of the fender can be suppressed.

In the saddle-ride type vehicle according to the second embodiment, the distance in the vehicle width direction between the pair of side stand portions 31m increases as the distance increases toward the front side in the vehicle longitudinal direction. The plurality of cross ribs 31n1, 31n2, 31n3, 31n4 are arranged in the vehicle longitudinal direction. The width in the vehicle width direction increases as the plurality of cross ribs 31n1, 31n2, 31n3, 31n4 are located further toward the front side in the vehicle longitudinal direction. The following effects are obtained by widening the width of the space between the pair of side frame portions 31m that become the flow path of the wind that the rear wheel 104 is caught in, as it is located on the front side (downstream side in the wheel rotation direction) of the rear wheel 104. That is, the flow of wind caught by the rear wheels 104 can be easily caused to flow outward in the vehicle width direction. Further, since the cover wall 31k on the front side of the rear wheel 104 is expanded, muddy water or the like is easily received, and scattering of muddy water or the like can be effectively suppressed.

In the saddle-ride type vehicle according to the second embodiment, the cross rib portions 31n1, 31n2, 31n3, 31n4 (specifically, the cross rib bodies 31w1, 31w2, 31w3, 31w 4) extend obliquely downward and forward from the lower surface 31p of the cover wall 31 k. This has the following effects as compared with the case where the lateral rib portions 31n1, 31n2, 31n3, 31n4 extend vertically downward. That is, the vertical thickness of the rear fender 31 can be suppressed, and the influence on the vehicle appearance can be suppressed. In addition, the front inclination of the cross ribs 31n1, 31n2, 31n3, 31n4 inclined obliquely downward and forward above the rear wheel 104 makes it easier for muddy water or the like adhering to the cross ribs 31n1, 31n2, 31n3, 31n4 to flow outward in the vehicle width direction than in the case of extending vertically. Accordingly, muddy water or the like can be easily transferred from the gaps between the side bracket portion 31m and the lateral rib portions 31n1, 31n2, 31n3, 31n 4.

The saddle-ride type vehicle according to the second embodiment includes a cover assembly 38 that is separate from the cover wall 31k and covers the upper surface 31v of the cover wall 31 k. This can improve the appearance of the rear fender 31. That is, even if air holes are generated in the upper surface 31v of the cover wall 31k by the formation of the side bracket portion 31m and the cross rib portions 31n1, 31n2, 31n3, 31n4, etc., the air holes can be hidden by the separate cover assembly 38.

In the saddle-ride type vehicle according to the second embodiment, at least one of the rear fender 31 and the cover assembly 38 supports the rear direction indicator lamp 53 and the license lamp 52. Thus, the wiring 75 reaching the license lamp 52 and the rear direction indicator lamp 53 can be hidden between the rear fender 31 and the hood assembly 38. Therefore, the wiring 75 can be protected, and the external appearance of the rear fender 31 can be improved.

In the saddle-ride type vehicle according to the second embodiment, the cross rib portions 31n1, 31n2, 31n3, 31n4 include plate-shaped cross rib bodies 31w1, 31w2, 31w3, 31w4 extending in the vehicle width direction, and leg portions 31y extending from the cross rib bodies 31w1, 31w2, 31w3, 31w4 to the lower surface 31p of the hood wall 31 k. The cross rib portions 31n1, 31n2, 31n3, 31n4 are constituted by plate-shaped cross rib bodies 31w1, 31w2, 31w3, 31w4 and leg portions 31y. Therefore, the following effects are achieved compared to the case where the lateral rib portions 31n1, 31n2, 31n3, 31n4 are formed in a solid block shape. That is, the weight of the lateral ribs 31n1, 31n2, 31n3, 31n4 can be suppressed. The cross ribs 31n1, 31n2, 31n3, 31n4 can be formed at a predetermined angle. This can suppress the weight of the rear fender 31.

In the saddle-ride type vehicle according to the second embodiment, a pair of side frames 31m and cross ribs 31n1, 31n2, 31n3, 31n4 of the rear fender 31 are provided above the air cleaner 109 having the intake port 109 a. This suppresses collision of wind flowing from the front of the vehicle with wind curled up by the rear wheels 104. By this effect, the influence of the amount of air taken into the air cleaner 109 can be suppressed. Further, the following effect is achieved by the configuration in which the gap 61 is provided between the side bracket portion 31m of the rear fender 31 and the lateral rib portions 31n1, 31n2, 31n3, 31n4. That is, muddy water or the like is easily transported to the front of the fender, and the muddy water or the like is prevented from falling down in the middle of the side stand portion 31 m. Accordingly, muddy water or the like falling in the middle can be suppressed from reaching the air inlet 109a of the air cleaner 109.

The present utility model is not limited to the above embodiments. For example, the side bracket portion 31m of the rear fender 31 has a U-shaped cross-sectional shape that is open upward and extends in the vehicle longitudinal direction, but is not limited thereto. For example, the side bracket portion 31m may be formed in a plate shape (wall shape) that is only erected downward from both side portions of the cover wall 31 k.

The plurality of cross ribs 31n1, 31n2, 31n3, 31n4 are provided with gaps 61 between them and the pair of side frames 31m, but the present utility model is not limited thereto. For example, the plurality of cross ribs 31n1, 31n2, 31n3, 31n4 may extend to the pair of side frames 31m (connected to the pair of side frames 31 m). The plurality of cross ribs 31n1, 31n2, 31n3, 31n4 are configured such that all of the base ends are connected to the cover wall 31k, but the present utility model is not limited thereto. For example, the plurality of cross ribs 31n1, 31n2, 31n3, 31n4 may be configured such that at least a part of the base end portion is separated from the cover wall 31k to allow wind or the like to flow.

The saddle-ride type vehicle includes all vehicles in which a driver rides over a vehicle body, and includes not only motor bicycles (including bicycles with a prime mover and scooter type vehicles) but also three-wheeled (vehicles including front two-wheeled and rear two-wheeled vehicles in addition to front two-wheeled and rear two-wheeled) and four-wheeled vehicles. In addition, a vehicle including an electric motor in a prime mover is also included.

The configuration of the above-described embodiment is an example of the present utility model, and the constituent elements of the embodiment may be replaced with known constituent elements or the like, and various modifications may be made without departing from the scope of the present utility model.
