[0011] The vehicle 100 is a scooter-type motorcycle in which a step floor 108 on which the rider's legs rest is provided between a steering handlebar 102 and a seat 109 on which the rider sits. The step floor 108 is covered from below by an undercover 11. The undercover 11 forms the bottom surface of the vehicle 100. A head pipe 104 is fixed to the front end of the body frame 101. The head pipe 104 rotatably supports a steering stem 103 extending downward from the steering handlebar 102. A pair of left and right front forks 105 that rotatably support a front wheel 110 are fixed to the lower part of the steering stem 103.

[0012] A front handle cowl 113 supporting a headlight 111 and a meter device 114 is provided in front of the steering handle 102 . steering A rear handle cowl 115 is provided on the rear side of the handle 102. A meter device 114 displays various information such as vehicle speed, remaining fuel, etc. The head pipe 104 and the steering stem 103 are covered with a cover 116. A front combination lamp 107 is provided at the front of the vehicle 100.

[0013] A unit swing type power unit 106, which is an integral combination of an engine 121 as a drive source and a transmission, is supported so as to be swingable about an axis in the D2 direction behind the step floor 108. The power unit 106 of this embodiment uses the engine 121, which is an internal combustion engine, as a drive source, but may use an electric motor as a drive source.

[0014] A rear wheel 112, which is a drive wheel, is rotatably supported by the power unit 106, and the power unit 106 rotates the rear wheel 112. The rear end of the power unit 106 is suspended from the vehicle body by a rear cushion 118.

[0015] An air cleaner 117 that supplies purified air to the engine 121 is attached above the power unit 106. The air cleaner 117 is disposed rearward of the step floor 108 in the D1 direction, and disposed on the left side of the vehicle 100. The air cleaner 117 has an air inlet 117a at a lower, rear position. Air introduced into the air cleaner 117 from the inlet 117a by negative pressure generated by the engine 121 is filtered by an air filter inside the air cleaner 117 and supplied to the engine 121.

[0016] Exhaust from the engine 121 is discharged through an exhaust pipe 122, a catalytic device 123, an exhaust pipe 124, and a muffler 125. The exhaust is purified by the catalytic device 123, and the exhaust noise is silenced by the muffler 125. The catalytic device 123 is disposed behind the under-cover 11 in the direction D1, and is disposed in such a position that the exhaust flow direction is the direction D2. The muffler 125 is disposed on the right side of the vehicle 100.

[0017] A side stand 119 is provided at the bottom of the left side of the vehicle 100. The side stand 119 is provided so as to be able to swing between an upright position shown by a dashed line in Fig. 1 and a stored position shown by a solid line in Fig. 1. In the upright position, the side stand 119 supports the vehicle body in a state in which the vehicle body is tilted to the left in the direction D2. At this time, the vehicle 100 is in contact with the ground at three points: the front wheel 110, the rear wheel 112, and the side stand 119.

[0018] A double-legged center stand 120 is provided at the bottom of the power unit 106. The center stand 120 is supported so as to be able to swing freely around an axis in the D2 direction, and when the center stand 120 is swung to an upright position, the vehicle can be parked without tilting to the left or right.

[0019] <Undercover> The structure of undercover 11 will be described with reference to Fig. 2 as well as Figs. 3 to 6. Fig. 3 is a plan view of cover member 1 forming undercover 11. Fig. 4 is a left side view of cover member 1. Fig. 5 is a bottom view of cover member 1. Fig. 6 is a cross-sectional view taken along line AA in Fig. 3 and a partially enlarged view.

[0020] The cover member 1 forms an undercover 11, left and right lower side covers 12R and 12L, and a front lower cover 13. The left and right lower side covers 12R and 12L partially form the left and right side portions of the vehicle 100. The front lower cover 13 is located behind the front wheels 110, and partially forms the front lower portion of the vehicle 100. The lower side covers 12R and 12L and the front lower cover 13 may be separate from the undercover 11.

[0021] The under-cover 11 is a plate-shaped member having an upper surface 11a and a bottom surface 11b. A notch 11c is formed in the rear end portion of the under-cover 11. The notch 11c prevents interference between the curved exhaust pipe 122 and the under-cover 11, and improves the degree of freedom in the layout of the exhaust pipe 122.

[0022] A pair of left and right rib rows 2L, 2R arranged in the D1 direction are formed on the bottom surface 11b. By forming the rib rows 2L, 2R, it is possible to prevent rainwater that adheres to the bottom surface 11b and flows rearward in the D1 direction during driving from scattering onto vehicle components rear of the under-cover 11. Specifically, for example, it is possible to prevent water from entering the inlet 117a of the air cleaner 117. In addition, by forming a pair of left and right rib rows 2L, 2R as in this embodiment, rather than forming the rib rows only on the left side or only on the right side, it is possible to suppress air resistance caused by the rib rows from being biased to the left or right during driving, and improve driving stability.

[0023] The left rib row 2L is made up of four ribs 3L to 6L protruding downward, and the right rib row 2R is made up of four ribs 3R to 6R protruding downward. The ribs 3L to 6L and the ribs 3R to 6R are formed symmetrically with respect to a center line CL in the D2 direction.

[0024] The rib row 2L and the rib row 2R are spaced apart in the D2 direction so that a space 11d without a rib is formed in the center of the under-cover 11 in the D2 direction. Since there is no rib, the traveling wind easily flows backward in the D1 direction in the space 11d as shown by the arrow d31. A part of the catalytic converter 123 is disposed behind the space 11d in the D1 direction. The traveling wind passing through the space 11d easily hits the catalytic converter 123, which contributes to cooling the catalytic converter 123. In the case of this embodiment, in particular, the rib row 2L and the rib row 2R are spaced apart on the outer side in the D2 direction from the width TW of the front wheel 110. During driving, the traveling wind flowing backward in the D1 direction from the left and right sides of the front wheel 110 easily flows into the space 11d. This further contributes to cooling the catalytic converter 123. The entire catalytic converter 123 may be disposed behind the space 11d in the D1 direction.

[0025] The ribs 3L to 6L are formed on the bottom surface 11b at a front surface 31 on the front side in the D1 direction, a top portion 32, and a rear surface on the rear side in the D1 direction. 33 and extends obliquely in the D2 direction. 33 is a flat inclined surface having a drop in the D3 direction. The front surface 31 is also an inclined surface having a drop in the D3 direction, but in this embodiment, it is a curved surface that is curved in a convex shape upward in the D3 direction. If the front surface 31 is a vertical surface, the effect of cutting water is improved, but the air resistance due to the wind while driving increases. If the front surface 31 is a flat inclined surface, the air resistance due to the wind while driving can be reduced, but the effect of cutting water is reduced. In this embodiment, by making the front surface 31 a curved surface, it is possible to achieve both the effect of cutting water and the reduction of air resistance.

[0026] The ribs 3L to 6L are convex portions curved downward from the upper surface 11a. In other words, the ribs 3L to 6L are groove portions extending obliquely in the direction D2 when viewed from the upper surface 11a. Rainwater and the like may accumulate here. As a countermeasure, in this embodiment, a drainage hole 9 penetrating the undercover 11 is formed in each of the ribs 3L to 6L. The drainage hole 9 may be formed in some of the ribs 3L to 6L. However, by forming the drainage holes 9 in all of the ribs 3L to 6L as in this embodiment, drainage performance can be improved.

[0027] In each of the ribs 3L to 6L, the water drainage hole 9 is formed on the side of the side stand 119 in the D2 direction, that is, on the left end (the end on the outer side in the D2 direction). When the vehicle 100 is parked using the side stand 119, water tends to collect in the water drainage hole 9 due to gravity, improving drainage.

[0028] The ribs 3L to 6L extend from the inside to the outside in the direction D2 and to the rear in the direction D1. Since the ribs 3L to 6L are inclined with respect to the direction D1, water that adheres to the under-cover 11 and flows rearward can be drained to the outside in the direction D2, and splashed water can be prevented from entering the inlet 117a of the air cleaner 117.

[0029] The extension directions of the ribs 3L to 6L are the d11 to d14 directions, respectively. The angle of the d11 direction with respect to the D2 direction is θ1, the angle of the d12 direction is θ2, the angle of the d13 direction is θ3, and the angle of the d14 direction is θ4. The magnitude relationship of the angles θ1 to θ4 is θ1>θ2>θ3>θ4. The extension direction of the rib located on the front side in the D1 direction is closer to the D2 direction than the extension direction of the rib located on the rear side. Since the extension direction of the rib located on the front side in the D1 direction has a large angle with respect to the D2 direction, water flowing rearward through the under-cover 11 can be easily discharged to the outside in the D2 direction, and air resistance due to traveling wind is also small. On the other hand, the extension direction of the rib located on the rear side in the D1 direction has a small angle with respect to the D2 direction, so that water flowing rearward through the under-cover 11 can be dropped downward in the D3 direction, and it is possible to more reliably prevent it from flowing further rearward.

[0030] In this embodiment, the angles θ1 to θ4 are all different angles, so that the water can be discharged outward in the direction D2 and downward in the direction D3 in a stepwise manner. However, the angles θ1 to θ4 do not all have to be different angles. For example, θ1<θ2=θ3<θ4 may be satisfied. Also, for example, θ1=θ2<θ3=θ4 may be satisfied.

[0031] The ribs 3L to 6L are arranged along the imaginary line LL. The imaginary line LL is a line inclined in the D2 direction with respect to the center line CL, and is inclined so that the distance between the imaginary line LL and the center line CL in the D2 direction is closer on the front side in the D1 direction and is greater on the rear side. Therefore, the inner end of the rear rib in the D2 direction is located outside in the D2 direction compared to the inner end of the front rib in the D1 direction. The airflow passing through the space 11d during driving is improved, and the air resistance caused by the formation of the ribs 3L to 6L can be reduced.

[0032] The ribs 3R to 6R have the same configuration as the ribs 3L to 6L. The ribs 3R to 6R also have water drainage holes 9, which are also formed on the side of the side stand 119 in the D2 direction, i.e., on the left end. However, when the position of the water drainage holes 9 is viewed from the inside to the outside in the D2 direction, unlike the ribs 3L to 6L, the water drainage holes 9 of the ribs 3R to 6R are located at the inner end in the D2 direction. To the department has been formed.

[0033] The extension directions of the ribs 3R to 6R are the d21 to d24 directions, respectively. With respect to the D2 direction, the angle of the d21 direction is θ1, the angle of the d22 direction is θ2, the angle of the d23 direction is θ3, and the angle of the d24 direction is θ4. The magnitude relationship of the angles θ1 to θ4 is as described for the ribs 3L to 6L.

[0034] The ribs 3R to 6R are arranged along the imaginary line LR. The imaginary line LR is symmetrical to the imaginary line LL with respect to the center line CL. The imaginary line LR is a line inclined in the D2 direction, and is inclined so that the distance between the imaginary line LR and the center line CL in the D2 direction is closer on the front side in the D1 direction and is farther away on the rear side. Therefore, the inner end of the rear rib in the D2 direction is located outside in the D2 direction compared to the inner end of the front rib in the D1 direction. In terms of the distance between the ribs 3L to 6L and the ribs 3R to 6R in the D2 direction, the distance between the rib 3L and the rib 3R is the narrowest, the distance between the rib 4L and the rib 4R is the second narrowest, the distance between the rib 6L and the rib 6R is the widest, and the distance between the rib 5L and the rib 5R is the second widest. In this way, the distance between the ribs 3L to 6L and the ribs 3R to 6R in the D2 direction is wider from the front side to the rear side in the D1 direction.

[0035] The airflow during travel passes through the space 11d more easily, and the air resistance caused by the formation of the ribs 3L to 6L and the ribs 3R to 6R can be reduced.

[0036] The under-cover 11 has a recess 7 formed at the front in the D1 direction and in the center in the D2 direction, which is convex upward in the D3 direction. The recess 7 forms a jack-up point. A reinforcing part 8 that abuts against the body frame 101 is formed at a portion of the upper surface 11a corresponding to the recess 7, and the recess 7 is located below the reinforcing part 8. Although the recess 7 is located in the space 11d, because it has an upward convex shape, it does not provide resistance to the wind flowing in the d31 direction.

[0037] <Other embodiments> In the above embodiment, each of the rib rows 2L and 2R is configured with four ribs, but the number of ribs may be two, three, or five or more. A smaller number of ribs reduces the drainage effect. A larger number of ribs improves the drainage effect, but there is a limit to the length of the undercover 11 in the D1 direction, which places restrictions on the layout of the ribs. By configuring each rib row with four ribs, it is possible to obtain a drainage effect while clearing the layout restrictions.
