Description

鞍乗り型車両saddle-riding vehicle
　本発明は、鞍乗り型車両に関する。 The present invention relates to a saddle-ride type vehicle.
　従来、スタンドの接地部にプレートを設けた鞍乗り型車両が知られている（例えば、特許文献１参照）。特許文献１には、左右一対の接地部分を備える鞍乗り型車両のスタンド装置が開示されており、スタンド装置の左右一対の接地部分には、プレートが設けられている。特許文献１のプレートの前面には、傾斜面が形成されている。 Conventionally, there is known a saddle-ride type vehicle in which a plate is provided on the contact portion of the stand (see Patent Document 1, for example).

　プレートの前面に傾斜面が形成されることで、接地部分のプレートに走行風が直接当たることによる空気抵抗を抑制することが可能である。しかしながら、特許文献１に記載の傾斜面では、走行風が傾斜面に沿って下方に案内され易く、後輪の接地荷重が小さくなり易いという課題がある。
　本発明は、上述した事情に鑑みてなされたものであり、スタンドが傾斜面を備える鞍乗り型車両において、走行風による空気抵抗を抑制しながら、後輪の接地荷重を高めることを目的とする。 By forming the inclined surface on the front surface of the plate, it is possible to suppress the air resistance caused by the running wind directly striking the plate at the ground contact portion. However, with the inclined surface described in Patent Document 1, there is a problem that the running wind tends to be guided downward along the inclined surface, and the ground load of the rear wheels tends to decrease.
SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances described above, and an object of the present invention is to increase the ground contact load of the rear wheels while suppressing the air resistance caused by the running wind in a saddle-ride type vehicle in which the stand has an inclined surface. .

Further, the right body fixing portion 54</b>C extends curvedly along the right portion of the body portion 51 . Here, the left main body fixing portion 53C is formed longer radially outward than the right main body fixing portion 54C. The main body fixing portion 53C on the left side extends to the rear side of the joint portion 57A (see FIG. 6) of the operation portion 57. As shown in FIG.
　第一プレート５３、５４に対して、回動軸部５２を挟んで反対側には、第二プレート５５、５６が固定されている。図５に示すように、第二プレート５５、５６は、面接触する第一プレート５３、５４に対して、いわば、線接触するように回動軸部５２および本体部５１に固定されている。すなわち、第二プレート５５、５６は、厚み方向が車幅方向に対応して固定されており、厚みの側面が回動軸部５２および本体部５１に固定される。よって、第一プレート５３、５４に比べて第二プレート５５、５６は、剛性が高くなり易い状態で回動軸部５２および本体部５１に固定される。 Second plates 55 and 56 are fixed on the opposite sides of the first plates 53 and 54 with the rotation shaft portion 52 interposed therebetween. As shown in FIG. 5, the second plates 55 and 56 are fixed to the rotating shaft portion 52 and the main body portion 51 so as to make line contact with the first plates 53 and 54 which are in surface contact. That is, the second plates 55 and 56 are fixed so that the thickness direction corresponds to the vehicle width direction, and the side surfaces of the thickness are fixed to the rotation shaft portion 52 and the main body portion 51 . Therefore, the second plates 55 and 56 are fixed to the rotation shaft portion 52 and the main body portion 51 in a state where the rigidity tends to be higher than that of the first plates 53 and 54 .
　図７に示すように、左右の第二プレート５５、５６は、径方向（前後方向）に延びており、平面視において、それぞれが、左右の第一プレート５３、５４に重複するように固定されている。第二プレート５５、５６は、回動軸部５２に固定された回動固定部５５Ａ、５６Ａと、回動固定部５５Ａ、５６Ａから径方向外側に延びる接続部５５Ｂ、５６Ｂと、接続部５５Ｂ、５６Ｂの径方向外端に形成されて本体部５１に固定された本体固定部５５Ｃ、５６Ｃと、を備える。左右の第二プレート５５、５６の本体固定部５５Ｃ、５６Ｃは、接続部５５Ｂ、５６Ｂから径方向に離間するに連れて車幅方向外側に湾曲している。 As shown in FIG. 7, the left and right second plates 55, 56 extend in the radial direction (front-rear direction) and are fixed so as to overlap the left and right first plates 53, 54 in plan view. ing.

The body fixing portions 55C and 56C of the left and right second plates 55 and 56 are curved outward in the vehicle width direction as they are radially separated from the connecting portions 55B and 56B.
　本体部５１の左脚部５１Ｂには、左方に延出する折り曲げパイプ状の操作部５７が固定されている。操作部５７は、正面視（図５参照）では、車幅方向外側に延びており、車幅方向外側に進むに連れて上方に傾斜している。また、操作部５７は、車両側面視（図４参照）では、上方に延出している。操作部５７の上端（先端）には、乗員が足で押すことが可能なペダルプレート５８が固定されている。ペダルプレート５８は、格納状態では、上方に進むに連れて後方に傾斜する板状に形成されている。 A bent pipe-shaped operating portion 57 extending leftward is fixed to the left leg portion 51B of the main body portion 51 . The operating portion 57 extends outward in the vehicle width direction when viewed from the front (see FIG. 5), and is inclined upward as it extends outward in the vehicle width direction. Further, the operating portion 57 extends upward when viewed from the side of the vehicle (see FIG. 4). A pedal plate 58 that can be pushed by the passenger's foot is fixed to the upper end (tip) of the operation portion 57 . The pedal plate 58 is formed in a plate shape that inclines rearward as it moves upward in the retracted state.
　操作部５７の外周面の前部には、板状の係合プレート５９が固定されている。係合プレート５９は、操作部５７の前部に沿って延びている。係合プレート５９は、操作部５７の外周面前部に突き当てられるように接合されている。係合プレート５９の車幅方向内端には、片状のばね係合部５９Ａが形成されている。ばね係合部５９Ａには、コイルバネ７０の一端７０Ａ（図６、図７参照）が引っ掛けて接続される。 A plate-shaped engagement plate 59 is fixed to the front portion of the outer peripheral surface of the operation portion 57 .

　操作部５７の外周面の後部には、板状のガセットプレート６０が固定されている。ガセットプレート６０は、操作部５７の後部に沿って延びている。ガセットプレート６０は、操作部５７の外周面後部に突き当てられるように接合されている。ガセットプレート６０の車幅方向内端は、本体部５１の左脚部５１Ｂに固定されている。ガセットプレート６０により操作部５７が補強されている。 A tabular gusset plate 60 is fixed to the rear portion of the outer peripheral surface of the operating portion 57 . A gusset plate 60 extends along the rear portion of the operating portion 57 . The gusset plate 60 is joined so as to abut against the rear portion of the outer peripheral surface of the operation portion 57 . The inner end of the gusset plate 60 in the vehicle width direction is fixed to the left leg portion 51B of the main body portion 51 . The gusset plate 60 reinforces the operating portion 57 .
　ガセットプレート６０に対して、本体部５１を挟んで車幅方向の反対側には、ダンパー部６１が設けられている。ダンパー部６１は、本体部５１に固定されたプレート部６２と、プレート部６２に固定されたラバー（緩衝部材）６３とを備える。ラバー６３は、前後方向に延びており、前方から見た断面では上部が波形状を有する（図８参照）。ダンパー部６１のラバー６３は、接地面プレート８０よりも上方に突出している（図４参照）。ダンパー部６１により、メインスタンド５０を起立状態から格納状態に移動させた場合に、メインスタンド５０が、過回動しても、パワーユニット１２の変速機ケース部４０に当たる衝撃を緩和可能になっている。 A damper portion 61 is provided on the opposite side of the gusset plate 60 in the vehicle width direction across the body portion 51 . The damper portion 61 includes a plate portion 62 fixed to the body portion 51 and a rubber (buffer member) 63 fixed to the plate portion 62 . The rubber 63 extends in the front-rear direction, and has a corrugated upper portion in a cross section viewed from the front (see FIG. 8). The rubber 63 of the damper portion 61 protrudes upward from the ground plane plate 80 (see FIG. 4). Even if the main stand 50 rotates excessively when the main stand 50 is moved from the upright state to the retracted state, the damper portion 61 can reduce the impact of the power unit 12 on the transmission case portion 40. .
　回動軸部５２には、車幅方向に延びる連結軸６４が挿通される。連結軸６４には、左端部（車幅方向一端部）に抜け止めプレート６５が固定されている。抜け止めプレート６５には、連結軸６４から偏心した位置に、ばね係合ピン６６が設けられている。ばね係合ピン６６は、抜け止めプレート６５に対して左方に突出する軸部材である。ばね係合ピン６６の先端部の外周面には、環状の嵌合溝６６Ａ（図６、図７参照）が形成されている。嵌合溝６６Ａには、コイルバネ７０の他端７０Ｂ（図６、図７参照）が接続される。 A connecting shaft 64 extending in the vehicle width direction is inserted through the rotating shaft portion 52 . A retainer plate 65 is fixed to the left end (one end in the vehicle width direction) of the connecting shaft 64 . The retainer plate 65 is provided with a spring engagement pin 66 at a position eccentric from the connecting shaft 64 . The spring engaging pin 66 is a shaft member that protrudes leftward with respect to the retainer plate 65 . An annular fitting groove 66A (see FIGS. 6 and 7) is formed on the outer peripheral surface of the tip of the spring engaging pin 66. As shown in FIG. The other end 70B (see FIGS. 6 and 7) of the coil spring 70 is connected to the fitting groove 66A.
　ここで、メインスタンド５０の回動軸部５２は、連結軸６４を介して、左右のスタンドブラケット２３ｂ、２３ｃ（図５参照）に支持される。すなわち、回動軸部５２は、左右のスタンドブラケット２３ｂ、２３ｃの間に配置されて、連結軸６４が、右端（先端）から挿通される。これにより、左側のスタンドブラケット２３ｂ、回動軸部５２、右側のスタンドブラケット２３ｃの順に連結軸６４が貫通する。そして、連結軸６４の右端部（車幅方向他端部）に、抜け止めピン６７が取り付けられると、抜け止めプレート６５と抜け止めピン６７により、連結軸６４が左右のスタンドブラケット２３ｂ、２３ｃから抜け止めされる。抜け止めプレート６５は、ボルト６８でクランクケース２３に固定される。
　よって、回動軸部５２が連結軸６４を中心として回動可能にスタンドブラケット２３ｂ、２３ｃに支持される。 Here, the pivot shaft portion 52 of the main stand 50 is supported by the left and right stand brackets 23b and 23c (see FIG. 5) via a connecting shaft 64. As shown in FIG. That is, the rotating shaft portion 52 is arranged between the left and right stand brackets 23b and 23c, and the connecting shaft 64 is inserted from the right end (tip). As a result, the connecting shaft 64 passes through the left stand bracket 23b, the rotation shaft portion 52, and the right stand bracket 23c in this order. When the retaining pin 67 is attached to the right end (the other end in the vehicle width direction) of the connecting shaft 64, the retaining plate 65 and the retaining pin 67 move the connecting shaft 64 from the left and right stand brackets 23b and 23c. It is stopped. The retainer plate 65 is fixed to the crankcase 23 with bolts 68 .
Therefore, the rotating shaft portion 52 is rotatably supported by the stand brackets 23b and 23c about the connecting shaft 64. As shown in FIG.
　メインスタンド５０が回動軸部５２を中心にして回動する場合に、ばね係合部５９Ａと、偏心したばね係合ピン６６との距離は変化し、最も離間する位置を跨いで起立状態と格納状態が設定されている。よって、起立状態と格納状態との間を移動する際に、コイルバネ７０は最大に延びた後に、起立状態と格納状態とのいずれかに移動する。コイルバネ７０の弾性復元力により、メインスタンド５０は、起立状態、格納状態のいずれかに保持される。 When the main stand 50 rotates around the rotation shaft portion 52, the distance between the spring engagement portion 59A and the eccentric spring engagement pin 66 changes, and the standing state straddles the most separated position. Stored state is set. Therefore, when moving between the upright state and the retracted state, the coil spring 70 extends to the maximum and then moves to either the upright state or the retracted state. The elastic restoring force of the coil spring 70 holds the main stand 50 in either an upright state or a retracted state.

The ground plane plates 80 and 90 fixed to the body portion 51 are formed by bending a metal plate material. The ground plane plates 80, 90 are press molded products.
　左側（車幅方向一側）の接地面プレート８０は、左脚部５１Ｂの下方に傾斜面８１を備える。傾斜面８１は、後方に進むに連れて下方に傾斜する板状に形成されている（図４参照）。傾斜面８１の前部（回動軸部５２側）には後方（回動軸部５２から径方向に離間する側）に凹んだ外周縁８１Ａが形成されている。外周縁８１Ａには、本体部５１の左脚部５１Ｂの外周面が沿った状態で配置される。傾斜面８１の後端には、上方に折れ曲がった板状の接地面８２が形成されている。 The ground contact plate 80 on the left side (one side in the vehicle width direction) has an inclined surface 81 below the left leg portion 51B. The sloped surface 81 is formed in a plate shape that slopes downward as it goes rearward (see FIG. 4). An outer peripheral edge 81A recessed rearward (toward the side away from the rotating shaft portion 52 in the radial direction) is formed on the front portion (on the rotating shaft portion 52 side) of the inclined surface 81 . The left leg portion 51B of the body portion 51 is arranged along the outer peripheral edge 81A along the outer peripheral surface thereof. At the rear end of the inclined surface 81, a plate-shaped ground contact surface 82 that is bent upward is formed.
　接地面８２は、台形状に形成されている（図９参照）。接地面８２は、上方に進むに連れて左右幅が大きくなるように形成される。接地面８２の車幅方向外縁（外端）は、車幅方向内縁（内端）よりも、上方に進むに連れて車幅方向外側に大きく傾斜している。
　また、接地面８２は、断面では、後方に凸で弧状に湾曲している（図１０参照）。接地面８２の内面には、左脚部５１Ｂの接地面５１Ｂ１が固定される。これにより、接地面プレート８０が、メインスタンド５０の本体部５１に固定される。 The ground plane 82 is formed in a trapezoidal shape (see FIG. 9). The ground contact surface 82 is formed so that its lateral width increases as it progresses upward. The vehicle width direction outer edge (outer end) of the ground contact surface 82 is inclined more outward in the vehicle width direction than the vehicle width direction inner edge (inner end).
In cross section, the ground contact surface 82 is convex backward and curved in an arc shape (see FIG. 10). The ground contact surface 51B1 of the left leg portion 51B is fixed to the inner surface of the ground contact surface 82. As shown in FIG. Thereby, the ground plane plate 80 is fixed to the body portion 51 of the main stand 50 .
　傾斜面８１の車幅方向内端には、上方に折れ曲がった板状の内端面８３が形成されている。内端面８３は、本体部５１の左脚部５１Ｂよりも車幅方向内側に配置される。内端面８３の後端と接地面８２の車幅方向内縁は溶接される。内端面８３と接地面８２とは接続されている。内端面８３と接地面８２との傾斜面８１側には、曲げ加工時の逃げ穴８０Ａ（図６参照）が形成されている。 A plate-shaped inner end surface 83 bent upward is formed at the inner end of the inclined surface 81 in the vehicle width direction. The inner end surface 83 is arranged inside the left leg portion 51B of the main body portion 51 in the vehicle width direction. The rear end of the inner end surface 83 and the inner edge of the ground contact surface 82 in the vehicle width direction are welded. The inner end face 83 and the ground plane 82 are connected. A clearance hole 80A (see FIG. 6) for bending is formed on the inclined surface 81 side between the inner end surface 83 and the ground surface 82 .
　傾斜面８１の車幅方向外端には、上方に折れ曲がった板状の外端面８４が形成されている。外端面８４は、車幅方向外側に進むに連れて上方に湾曲した板状である。外端面８４は、図８、図９に示すように、本体部５１の左脚部５１Ｂに重複する位置から左脚部５１Ｂよりも車幅方向外側に延出している。外端面８４は、接地面８２の車幅方向外縁に沿って車幅方向外側に湾曲している。外端面８４と接地面８２との間は溶接されていない。外端面８４と接地面８２との傾斜面８１側には、曲げ加工時の逃げ穴８０Ｂ（図６参照）が形成されている。 A plate-like outer end surface 84 bent upward is formed at the outer end of the inclined surface 81 in the vehicle width direction. The outer end surface 84 has a plate-like shape that curves upward toward the outside in the vehicle width direction. As shown in FIGS. 8 and 9 , the outer end surface 84 extends outward in the vehicle width direction from a position overlapping the left leg portion 51B of the body portion 51 . The outer end surface 84 curves outward in the vehicle width direction along the vehicle width direction outer edge of the ground contact surface 82 . There is no welding between the outer end surface 84 and the ground surface 82 . A clearance hole 80B (see FIG. 6) for bending is formed on the inclined surface 81 side between the outer end surface 84 and the ground surface 82 .
　傾斜面８１には、内面側が凹んで外面側に突出する凸部８５が形成されている。凸部８５は傾斜面８１に対して下方に突出する。本実施の形態では、凸部８５は、左右に延びる軸線を有する円筒の側面形状、すなわち、円筒面形状をしている。凸部８５は、傾斜面８１に対して最大の突出高さ（突出量）となる頂部８５Ａ（図１０参照）が前下方を指向している。頂部８５Ａは、円筒形状の軸線に沿って左右方向に延びている。凸部８５は、曲率が小さい円筒面形状であり、前後方向で、傾斜面８１に向けて徐々に突出高さが低くなり緩やかな傾斜で傾斜面８１に接続されている。頂部８５Ａは、凸部８５の前後方向中心部に形成されている。 The inclined surface 81 is formed with a convex portion 85 that is concave on the inner surface side and protrudes on the outer surface side. The convex portion 85 protrudes downward with respect to the inclined surface 81 . In the present embodiment, the convex portion 85 has a side surface shape of a cylinder having an axis extending left and right, that is, a cylindrical surface shape. The convex portion 85 has a top portion 85A (see FIG. 10), which has the maximum protrusion height (protrusion amount) with respect to the inclined surface 81, and is oriented forward and downward. The top portion 85A extends in the left-right direction along the axis of the cylindrical shape. The convex portion 85 has a cylindrical surface shape with a small curvature, and is connected to the inclined surface 81 with a gentle inclination while gradually lowering the projecting height toward the inclined surface 81 in the front-rear direction. The top portion 85A is formed at the central portion of the convex portion 85 in the front-rear direction.
　凸部８５は、傾斜面８１に向けて車幅方向外側に突出高さが低くなる。本実施の形態では、凸部８５の車幅方向の両方の外端には、車幅方向外側に進むに連れて上方に傾斜する傾斜部８５Ｂが形成されている（図９参照）。凸部８５は、車幅方向では、傾斜部８５Ｂ以外は突出量が略均一になっている。傾斜部８５Ｂにより、凸部８５は、車幅方向でも、傾斜面８１に緩やかな傾斜で接続され易くなっている。
　凸部８５は、前後方向では、傾斜面８１に対して４５°よりも小さい傾斜角度で接続されている（図１０参照）。凸部８５は、傾斜部８５Ｂにより、車幅方向では、傾斜面８１に対して９０°よりも小さい傾斜角度で接続されている（図９参照）。凸部８５は、前後方向が、車幅方向よりも、傾斜面８１に対して小さい傾斜角度で接続されている。 The protrusion 85 protrudes toward the inclined surface 81 toward the outer side in the vehicle width direction and has a lower protrusion height. In the present embodiment, inclined portions 85B that incline upward toward the outside in the vehicle width direction are formed at both outer ends of the convex portion 85 in the vehicle width direction (see FIG. 9). The convex portion 85 has a substantially uniform amount of protrusion in the vehicle width direction except for the inclined portion 85B. The inclined portion 85B makes it easy for the convex portion 85 to be connected to the inclined surface 81 with a gentle inclination even in the vehicle width direction.
The convex portion 85 is connected to the inclined surface 81 at an inclination angle smaller than 45° in the front-rear direction (see FIG. 10). The convex portion 85 is connected to the inclined surface 81 in the vehicle width direction by an inclined portion 85B at an inclination angle smaller than 90° (see FIG. 9). The convex portion 85 is connected to the inclined surface 81 at a smaller angle of inclination in the front-rear direction than in the vehicle width direction.
　外端面８４には、内面側が凹んで外面側に突出する第二凸部８６が形成されている。第二凸部８６は外端面８４に対して突出し車幅方向外側下方に指向する。本実施の形態では、第二凸部８６は、上下方向に沿って延びる軸線を有する円筒の側面形状をしている（図４参照）。第二凸部８６の頂部８６Ａ（図６参照）は、第二凸部８６の円筒形状の軸線に沿って延びている。第二凸部８６は、曲率が小さい円筒面形状であり、外端面８４に対して、前側から徐々に突出高さが高くなるように延びて、緩やかな傾斜で接続されている。頂部８６Ａは、第二凸部８６の前後方向中心部に形成されている。第二凸部８６は、前側では、外端面８４に対して４５°よりも小さい角度で接続されている（図１０参照）。 The outer end surface 84 is formed with a second convex portion 86 which is recessed on the inner surface side and protrudes on the outer surface side. The second convex portion 86 protrudes from the outer end surface 84 and is oriented downward and outward in the vehicle width direction. In the present embodiment, the second convex portion 86 has a cylindrical side surface shape having an axis extending in the vertical direction (see FIG. 4). A top portion 86A (see FIG. 6) of the second protrusion 86 extends along the axis of the cylindrical shape of the second protrusion 86. As shown in FIG. The second convex portion 86 has a cylindrical surface shape with a small curvature, extends from the front side so as to gradually increase in height, and is connected to the outer end surface 84 with a gentle slope. The top portion 86A is formed at the center portion of the second protrusion 86 in the front-rear direction. The second convex portion 86 is connected to the outer end surface 84 at an angle smaller than 45° on the front side (see FIG. 10).
　本体部５１の右脚部５１Ｃの接地面５１Ｃ１（図３、図７参照）には、右側（車幅方向他側）の接地面プレート９０が固定されている。右側の接地面プレート９０では、左側の接地面プレート８０の外端面８４が省略されている点以外は、左側の接地面プレート９０と略左右対称に構成される。すなわち、右側の接地面プレート９０は、左側の接地面プレート８０の傾斜面８１、接地面８２、内端面８３、凸部８５、頂部８５Ａ、傾斜部８５Ｂ、逃げ穴８０Ａに対応して、傾斜面９１、接地面９２、内端面９３、凸部９５、頂部９５Ａ、傾斜部９５Ｂ、逃げ穴９０Ａを備える。 A ground plane plate 90 on the right side (the other side in the vehicle width direction) is fixed to the ground plane 51C1 (see FIGS. 3 and 7) of the right leg portion 51C of the main body portion 51 . The right ground plane plate 90 is configured substantially bilaterally symmetrical with the left ground plane plate 90 except that the outer end face 84 of the left ground plane plate 80 is omitted. That is, the right tread plate 90 corresponds to the slanted surface 81, the tread 82, the inner end surface 83, the convex portion 85, the top portion 85A, the slanted portion 85B, and the escape hole 80A of the left tread plate 80. 91, a ground surface 92, an inner end surface 93, a convex portion 95, a top portion 95A, an inclined portion 95B, and an escape hole 90A.
　右側の凸部９５は、図５に示すように、左側の凸部８５に比べて車幅方向に幅広に形成されている。右側の凸部９５では、車幅方向外端の傾斜部９５Ｂが省略されている。これにより、メインスタンド５０において、左右の接地面プレート８０、９０の構成を変化させることができ、例えば、右側に設けられた排気装置２５のマフラー２５Ａ（図３参照）の重量を考慮して、左右で走行風を受ける影響のバランスをとることができる。 As shown in FIG. 5, the right convex portion 95 is wider in the vehicle width direction than the left convex portion 85 . In the convex portion 95 on the right side, the inclined portion 95B at the outer end in the vehicle width direction is omitted. As a result, in the main stand 50, the configuration of the left and right tread plates 80, 90 can be changed. It is possible to balance the influence of the running wind on the left and right.
　接地面プレート９０の前方の右脚部５１Ｃには、ガイドプレート９６が固定されている。ガイドプレート９６は、図５に示すように、車幅方向外側に凸に弧状に湾曲した湾曲板状である。ガイドプレート９６は、後方に進むに連れて幅広に形成されている。ガイドプレート９６は、正面視では、接地面プレート９０の接地面９２に重複している。ガイドプレート９６により、前方から当たる走行風や水を、車幅方向外側に案内し易くなっており、右側の接地面プレート９０の接地面９２の内面（前面）に走行風や水が当たることを抑制している。 A guide plate 96 is fixed to the front right leg portion 51C of the ground plane plate 90 . As shown in FIG. 5, the guide plate 96 is in the shape of a curved plate that is convex outward in the vehicle width direction. The guide plate 96 is formed wider as it goes rearward. The guide plate 96 overlaps the ground plane 92 of the ground plane plate 90 when viewed from the front. The guide plate 96 makes it easy to guide wind and water coming from the front toward the outside in the vehicle width direction, so that the inner surface (front) of the ground contact surface 92 of the right ground contact plate 90 is prevented from being hit by running wind and water. suppressed.
　次に、本実施の形態の作用を説明する。
　鞍乗り型車両１０は、駐車時には、例えば、メインスタンド５０が起立状態にされ、メインスタンド５０の接地面プレート８０、９０が接地された状態で駐車される。そして、鞍乗り型車両１０が走行する際には、メインスタンド５０が起立状態から格納状態に回動される。 Next, the operation of this embodiment will be described.
When the saddle-riding vehicle 10 is parked, for example, the main stand 50 is set up and the ground plane plates 80 and 90 of the main stand 50 are parked. When the saddle-ride type vehicle 10 travels, the main stand 50 is rotated from the upright state to the retracted state.
　鞍乗り型車両１０は走行する場合に前方から走行風を受ける。このとき、メインスタンド５０では、図２、図３の矢印Ａ１～Ａ３で示すように、傾斜面８１、９１に沿って走行風が流れる。本実施の形態では、傾斜面８１、９１に凸部８５、９５が設けられているため、凸部８５、９５によって走行風が案内される。すなわち、走行風は、凸部８５、９５によってメインスタンド５０から離間する後下方向に案内されると共に、凸部８５、９５によって接地面プレート８０、９０に沿った上方に案内される。よって、傾斜面８１、９１に凸部８５、９５が設けられていない場合に比べて、凸部８５、９５により下方に案内される走行風が少なくなっており、走行風による揚力が抑制されて後輪１５の接地荷重を増大させ易くなっている。 The saddle-ride type vehicle 10 receives running wind from the front when running. At this time, in the main stand 50, running wind flows along the inclined surfaces 81 and 91 as indicated by arrows A1 to A3 in FIGS. In the present embodiment, since the convex portions 85 and 95 are provided on the inclined surfaces 81 and 91, the traveling wind is guided by the convex portions 85 and 95. As shown in FIG. That is, the running wind is guided downward and rearward away from the main stand 50 by the projections 85 and 95 and is guided upward along the ground plane plates 80 and 90 by the projections 85 and 95 . Therefore, compared to the case where the convex portions 85 and 95 are not provided on the inclined surfaces 81 and 91, the traveling wind guided downward by the convex portions 85 and 95 is reduced, and the lift force due to the traveling wind is suppressed. It is easy to increase the ground load of the rear wheel 15 .
　また、凸部８５、９５は、車幅方向に対しても、傾斜面８１、９１に向けて車幅方向外側に突出高さが低くなりながら接続されている。このため、鞍乗り型車両１０が旋回したり、バンクしたりして、鞍乗り型車両１０がロール方向に回転した場合にも走行風の流れを案内し易くなっている。 In addition, the protrusions 85 and 95 are also connected to the inclined surfaces 81 and 91 in the vehicle width direction while the height of the protrusions decreases outward in the vehicle width direction. Therefore, even when the saddle-ride type vehicle 10 turns or bank, and the saddle-ride type vehicle 10 rotates in the roll direction, it is easy to guide the flow of traveling wind.
　特に、本実施の形態では、メインスタンド５０はクランクケース２３に支持されており、後輪１５に車両側面視で重複する。よって、メインスタンド５０は、鞍乗り型車両１０の重心から遠い位置に設けられると共に後輪１５に近いため、車体後部への影響を与え易い位置に設けられている。本実施の形態では、このメインスタンド５０に、凸部８５、９５を有する接地面プレート８０、９０が設けられるため、適切に後輪１５の接地荷重を増大させ易くなっている。また、メインスタンド５０の左右の接地面プレート８０、９０の形状を変えることにより、左右の姿勢変化を調整することができる。 In particular, in the present embodiment, the main stand 50 is supported by the crankcase 23 and overlaps the rear wheel 15 when viewed from the side of the vehicle. Therefore, the main stand 50 is provided at a position far from the center of gravity of the saddle-ride type vehicle 10 and close to the rear wheels 15, so that the main stand 50 is provided at a position that easily affects the rear portion of the vehicle body. In the present embodiment, the main stand 50 is provided with the ground plane plates 80 and 90 having the projections 85 and 95, so that the ground load of the rear wheel 15 can be increased appropriately. In addition, by changing the shape of the left and right ground plane plates 80 and 90 of the main stand 50, it is possible to adjust the left and right attitude changes.
　なお、左側の接地面プレート８０には、外端面８４が形成されている。外端面８４により、走行風が車幅方向外側に案内される。この際に、例えば、路上の水が跳ね上げられて走行風と共に接地面プレート８０に向かう場合があるが、走行風や水が、外端面８４により車幅方向外側下方に案内され易く、接地面９２に水が進入することが抑制されている。よって、接地面８２の内面に水が進入して、エアクリーナーボックス４５の吸気口４５ａに向かって水が跳ね上がることが抑制されている。 An outer end surface 84 is formed on the left ground plane plate 80 . The outer end surface 84 guides the running wind outward in the vehicle width direction. At this time, for example, water on the road may be splashed up and headed toward the ground contact plate 80 together with the running wind. Intrusion of water into 92 is suppressed. Therefore, water is prevented from entering the inner surface of the ground contact surface 82 and splashing up toward the intake port 45 a of the air cleaner box 45 .
　以上説明したように、本発明を適用した実施の形態によれば、メインスタンド５０の本体部５１と、本体部５１の接地面５１Ｂ１、５１Ｃ１に取り付けられた接地面プレート８０、９０と、メインスタンド５０が走行時の格納状態で接地面プレート８０、９０の前側となる部分に設けられた傾斜面８１、９１と、を備える鞍乗り型車両１０において、傾斜面８１、９１には、メインスタンド５０が走行時の格納状態で傾斜面８１、９１から前下方に突出した凸部８５、９５を備える。したがって、メインスタンド５０が傾斜面８１、９１を備える鞍乗り型車両１０において、走行風による空気抵抗を抑制しながら、後輪１５の接地荷重を高めることができる。 As described above, according to the embodiment to which the present invention is applied, the body portion 51 of the main stand 50, the ground plane plates 80 and 90 attached to the ground planes 51B1 and 51C1 of the main stand 51, and the main stand Sliding surfaces 81 and 91 are provided on the front side of the tread plates 80 and 90 when the saddle-ride type vehicle 10 is in a retracted state during traveling. is provided with protrusions 85, 95 protruding forward and downward from the inclined surfaces 81, 91 in a stored state during traveling. Therefore, in the saddle-ride type vehicle 10 in which the main stand 50 includes the inclined surfaces 81 and 91, the ground load of the rear wheels 15 can be increased while suppressing air resistance due to running wind.
　本実施の形態では、メインスタンド５０の本体部５１には、車幅方向に一対の接地面プレート８０、９０が設けられている。したがって、車幅方向で走行風を受けることができ、車幅方向で走行風の影響のバランスをとることができる。 In the present embodiment, the body portion 51 of the main stand 50 is provided with a pair of ground plane plates 80 and 90 in the vehicle width direction. Therefore, the traveling wind can be received in the vehicle width direction, and the influence of the traveling wind can be balanced in the vehicle width direction.
　また、本実施の形態では、凸部８５、９５は、車幅方向における傾斜面８１、９１との接続部分が、傾斜面８１、９１に向けて車幅方向外側に突出高さが低くなる。したがって、凸部８５、９５が車幅方向で傾斜面８１、９１から徐々に突出する形状となるため、車体がバンク等で傾斜する際の空気抵抗を減らすことができる。 In addition, in the present embodiment, the connecting portions of the convex portions 85 and 95 with the inclined surfaces 81 and 91 in the vehicle width direction protrude outward toward the inclined surfaces 81 and 91 and have a lower height. Therefore, since the convex portions 85 and 95 gradually protrude from the inclined surfaces 81 and 91 in the vehicle width direction, it is possible to reduce the air resistance when the vehicle body leans on a bank or the like.
　また、本実施の形態では、メインスタンド５０が走行時の格納状態で、凸部８５、９５は、傾斜面８１、９１に対する傾斜角度が、車幅方向より、前後方向が小さくなる。したがって、凸部８５、９５が、傾斜面８１、９１に対する傾斜が緩やかな前後形状を有するため、後輪１５の接地荷重をより高めることができる。 Also, in the present embodiment, when the main stand 50 is in the retracted state during traveling, the angles of inclination of the projections 85 and 95 with respect to the inclined surfaces 81 and 91 are smaller in the front-rear direction than in the vehicle width direction. Therefore, since the convex portions 85 and 95 have a front-to-rear shape with a gentle inclination with respect to the inclined surfaces 81 and 91, the ground load of the rear wheel 15 can be further increased.
　また、本実施の形態では、メインスタンド５０が走行時の格納状態で、凸部８５、９５の頂部８５Ａ、９５Ａが凸部８５、９５の前後中心部に位置する。したがって、前後中心部に頂部８５Ａ、９５Ａが位置するため、走行風をバランス良く案内し易く、後輪１５の接地荷重をより高めることができる。 Also, in the present embodiment, the tops 85A, 95A of the projections 85, 95 are positioned at the front-rear center of the projections 85, 95 when the main stand 50 is in the retracted state during running. Therefore, since the apex portions 85A and 95A are positioned at the front and rear center portions, it is easy to guide the running wind in a well-balanced manner, and the ground load of the rear wheels 15 can be further increased.
