The extension line L is an imaginary straight line extending rearward and upward from the rear edge portion 40a at the central portion in the vehicle width direction.
2 to 5, the front edge 47a of the upper cover front surface 47 is located behind the extension line L when viewed from the side of the vehicle (FIG. 2). Further, the front edge 47 a is located forward of the rear edge 41 a of the upper surface portion 41 of the front cover 30 when viewed from the side of the vehicle.
The front edge 47 a is positioned at substantially the same height as the rear edge portion 40 a of the front surface 40 of the front cover 30 .
The front edge 47a, the concave portion 50, and the convex portion 51 overlap the extension line L in plan view in FIG.
　凹部５０の底面５０ａは、車両側面視で後上がりに傾斜する傾斜面である。底面５０ａは、車両側面視で、延長線Ｌ上に位置する。底面５０ａは、車両側面視で、延長線Ｌに重なっており、延長線Ｌと略平行である。 A bottom surface 50a of the recessed portion 50 is an inclined surface that is inclined upwardly rearward when viewed from the side of the vehicle. The bottom surface 50a is positioned on the extension line L when viewed from the side of the vehicle. The bottom surface 50a overlaps the extension line L and is substantially parallel to the extension line L when viewed from the side of the vehicle.
　凸部５１は、車両側面視で、延長線Ｌに対し前方且つ上方に突出する。
　凸部５１の前壁部５１ａは、延長線Ｌに対し上方に突出する。
　延長線Ｌは、前壁部５１ａの下部に交差する。
　前壁部５１ａは、車両側面視で、後上がりに傾斜する傾斜面である。前壁部５１ａの傾斜は、凹部５０の底面５０ａの傾斜よりも鉛直に近い。 The convex portion 51 protrudes forward and upward with respect to the extension line L when viewed from the side of the vehicle.
A front wall portion 51a of the convex portion 51 protrudes upward with respect to the extension line L. As shown in FIG.
The extension line L intersects the lower portion of the front wall portion 51a.
The front wall portion 51a is an inclined surface that is inclined rearwardly upward when viewed from the side of the vehicle. The slope of the front wall portion 51 a is closer to vertical than the slope of the bottom surface 50 a of the recess 50 .
　フロントカバー３０の前方側では、自動二輪車１の走行に伴う走行風Ｗは前面４０に沿って後上方に流れる。
　前面４０に沿って流れる走行風Ｗの一部は、前面４０の後縁部４０ａから延長線Ｌに沿って後上方に流れ、その後、アッパーカバー前面４７に沿って後上方に流れる。
　詳細には、走行風Ｗは、アッパーカバー前面４７の前縁４７ａのやや前方側を通ってアッパーカバー前面４７の下部に当たり、その後、凹部５０内を流れる。前縁４７ａが延長線Ｌよりも後方に位置するため、走行風Ｗがアッパーカバー前面４７に当たり易い。例えば、前縁４７ａが延長線Ｌよりも前方に位置する場合、延長線Ｌに沿う走行風Ｗは、アッパーカバー下面部４８側に流れ易くなり、アッパーカバー前面４７側には流れ難い。 On the front side of the front cover 30 , the running wind W caused by running of the motorcycle 1 flows rearward and upward along the front surface 40 .
A portion of the running wind W flowing along the front surface 40 flows rearward and upward along the extension line L from the rear edge portion 40 a of the front surface 40 , and then flows rearward and upward along the upper cover front surface 47 .
Specifically, the running wind W passes through the front edge 47 a of the upper cover front surface 47 slightly forward, hits the lower portion of the upper cover front surface 47 , and then flows inside the recess 50 . Since the front edge 47a is located behind the extension line L, the running wind W easily hits the front surface 47 of the upper cover. For example, when the front edge 47a is located forward of the extension line L, the running wind W along the extension line L tends to flow toward the upper cover lower surface portion 48 side, but hardly flows toward the upper cover front surface 47 side.
　走行風Ｗは、凹部５０では、凹部５０の左右の側壁部５０ｂによって車幅方向にガイドされるとともに、底面５０ａに沿って後上方に流れる。走行風Ｗは、左右の側壁部５０ｂの間を流れることで、後上方への指向性が強くなる。
　凹部５０を流れる走行風Ｗは、凸部５１の前壁部５１ａに当たり、前壁部５１ａに沿って後上方に流れる。前壁部５１ａの傾斜は、底面５０ａの傾斜よりも鉛直に近いため、走行風Ｗは、上方向に強く指向する。 In the recessed portion 50, the running wind W is guided in the vehicle width direction by the left and right side wall portions 50b of the recessed portion 50 and flows rearward and upward along the bottom surface 50a. The traveling wind W flows between the left and right side wall portions 50b, so that directivity in the rearward upper direction becomes stronger.
The running wind W flowing through the concave portion 50 hits the front wall portion 51a of the convex portion 51 and flows rearward and upward along the front wall portion 51a. Since the slope of the front wall portion 51a is closer to the vertical than the slope of the bottom surface 50a, the running wind W is strongly directed upward.
　このように、自動二輪車１では、フロントカバー３０の前面４０に沿って流れる走行風Ｗを効率良くアッパーカバー前面４７に当てて、走行風Ｗをアッパーカバー前面４７によって後上方に逃がすことができる。このため、アッパーカバー３１の後方でシート１３に着座する乗員の側に流れる走行風Ｗの量を減らすことができる。 Thus, in the motorcycle 1, the running wind W flowing along the front face 40 of the front cover 30 is efficiently applied to the upper cover front face 47, and the running wind W can be escaped rearward and upward by the upper cover front face 47. Therefore, it is possible to reduce the amount of running wind W that flows toward the passenger seated on the seat 13 behind the upper cover 31 .
　アッパーカバー３１は、ハンドル２０に取り付けられており、ハンドル２０が操舵される際には、ハンドル２０と一体に左右に回動する。
　アッパーカバー前面４７の前縁４７ａは、フロントカバー３０の後縁部４０ａから後方に離間する。また、前縁４７ａから後方に延びるアッパーカバー下面部４８とフロントカバー３０の上面部４１との間には上下に隙間５２が設けられる。このため、アッパーカバー３１が左右に回動する際に、フロントカバー３０の後縁部４０ａとアッパーカバー３１との間に大きな空間を確保でき、アッパーカバー３１を容易に回動させることができる。
　上面部４１は、車幅方向において後縁部４０ａと略同一の範囲に亘って設けられる。 The upper cover 31 is attached to the steering wheel 20, and rotates left and right together with the steering wheel 20 when the steering wheel 20 is steered.
A front edge 47 a of the upper cover front surface 47 is spaced rearward from the rear edge portion 40 a of the front cover 30 . A gap 52 is vertically provided between the upper cover lower surface portion 48 extending rearward from the front edge 47 a and the upper surface portion 41 of the front cover 30 . Therefore, when the upper cover 31 rotates left and right, a large space can be secured between the rear edge portion 40a of the front cover 30 and the upper cover 31, and the upper cover 31 can be easily rotated.
The upper surface portion 41 is provided over substantially the same range as the rear edge portion 40a in the vehicle width direction.
　図３に示すように、上面視では、フロントカバー３０の後縁部４０ａは、後縁部４０ａの車幅方向の中央部が最も前方に位置するように前方に凸に湾曲している。このため、アッパーカバー３１の前縁４７ａとフロントカバー３０の後縁部４０ａとのクリアランスを大きく確保でき、アッパーカバー３１を容易に回動させることができる。 As shown in FIG. 3, when viewed from the top, the rear edge portion 40a of the front cover 30 is curved forward so that the central portion of the rear edge portion 40a in the vehicle width direction is positioned furthest forward. Therefore, a large clearance can be secured between the front edge 47a of the upper cover 31 and the rear edge 40a of the front cover 30, and the upper cover 31 can be easily rotated.
　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、自動二輪車１は、前輪２の上方で車体フレーム１０を前方から覆うフロントカバー３０と、フロントカバー３０の上方で操舵用のハンドル２０を前方から覆うアッパーカバー３１とを備え、車両側面視でフロントカバー３０の前面４０及びアッパーカバー３１の前面であるアッパーカバー前面４７が後上がりに傾斜し、車両側面視で、アッパーカバー前面４７の前縁４７ａは、フロントカバー３０の前面４０の後縁部４０ａをこの後縁部４０ａに沿って後上方に延長した延長線Ｌよりも後方に位置する。
　この構成によれば、フロントカバー３０の前面４０に沿って後縁部４０ａから後上方に流れる走行風Ｗの一部は、アッパーカバー３１の前縁４７ａからアッパーカバー前面４７に沿って後上方に流れるため、走行風Ｗを効率良く上方に逃がすことができる。このため、乗員側に流れる走行風Ｗを低減できる。 As described above, according to the embodiment to which the present invention is applied, the motorcycle 1 includes the front cover 30 covering the body frame 10 from the front above the front wheels 2 and the steering wheel above the front cover 30. The front surface 40 of the front cover 30 and the upper cover front surface 47, which is the front surface of the upper cover 31, are inclined rearwardly upward when viewed from the side of the vehicle. The front edge 47a of the front cover 30 is positioned rearward of an extension line L that extends rearward and upward along the rear edge portion 40a of the front surface 40 of the front cover 30 .
According to this configuration, part of the running wind W flowing rearwardly upward from the rear edge portion 40a along the front surface 40 of the front cover 30 flows rearwardly upward from the front edge 47a of the upper cover 31 along the upper cover front surface 47. Since it flows, the running wind W can be efficiently released upward. Therefore, the running wind W flowing toward the passenger can be reduced.
　また、アッパーカバー前面４７は、下方に凹む凹部５０を備え、凹部５０の底面５０ａは、車両側面視で延長線Ｌ上に位置する。
　この構成によれば、フロントカバー３０から延長線Ｌに沿うように後上方に流れる走行風Ｗを、凹部５０の底面５０ａに沿わせてスムーズに流すことができる。また、走行風Ｗは、凹部５０に集まって後上方に流れるため、走行風Ｗの後上方への指向性を強くできる。
　また、アッパーカバー前面４７は、上方に突出する凸部５１を備え、凸部５１は、車両側面視で延長線Ｌに対し前方に突出する。
　この構成によれば、走行風Ｗは、延長線Ｌに対し前方に突出する凸部５１に当たることで、上方側に流れる。このため、乗員側に流れる走行風を低減できる。 Further, the upper cover front surface 47 is provided with a recessed portion 50 that is recessed downward, and the bottom surface 50a of the recessed portion 50 is positioned on the extension line L when viewed from the side of the vehicle.
According to this configuration, the running wind W flowing rearward and upward from the front cover 30 along the extension line L can be smoothly flowed along the bottom surface 50 a of the recess 50 . In addition, since the running wind W gathers in the concave portion 50 and flows rearwardly upward, the directionality of the running wind W in the rearwardly upward direction can be strengthened.
Further, the upper cover front surface 47 has a convex portion 51 that protrudes upward, and the convex portion 51 protrudes forward with respect to the extension line L when viewed from the side of the vehicle.
According to this configuration, the running wind W hits the convex portion 51 projecting forward with respect to the extension line L, and flows upward. Therefore, it is possible to reduce the running wind that flows toward the passenger.
　さらに、車両前方側から順に、前縁４７ａ、凹部５０、及び凸部５１が配置される。
　この構成によれば、前縁４７ａからアッパーカバー前面４７に沿って流れる走行風Ｗは、凹部５０に集まり、その後、凸部５１に当たって上方に流れる。このため、乗員側に流れる走行風Ｗを低減できる。
　また、アッパーカバー３１は、ハンドル２０と一体に左右に回動し、アッパーカバー３１は、前縁４７ａから後方に延びるアッパーカバー下面部４８を備え、フロントカバー３０は、アッパーカバー下面部４８の下方に位置する上面部４１を、後縁部４０ａの後下方に備え、アッパーカバー下面部４８と上面部４１との間に隙間５２が形成される。
　この構成によれば、左右に回動するアッパーカバー３１とフロントカバー３０の上面部４１との間に隙間５２を確保できるため、アッパーカバー３１を回動させ易い。 Furthermore, the front edge 47a, the concave portion 50, and the convex portion 51 are arranged in this order from the front side of the vehicle.
According to this configuration, the running wind W flowing from the front edge 47a along the upper cover front surface 47 gathers in the concave portion 50 and then hits the convex portion 51 and flows upward. Therefore, the running wind W flowing toward the passenger can be reduced.
The upper cover 31 rotates left and right integrally with the handle 20. The upper cover 31 has an upper cover lower surface portion 48 extending rearward from the front edge 47a. A gap 52 is formed between the lower surface portion 48 and the upper surface portion 41 of the upper cover.
According to this configuration, the gap 52 can be secured between the upper cover 31 that rotates left and right and the upper surface portion 41 of the front cover 30, so that the upper cover 31 can be easily rotated.
　また、上面視で、フロントカバー３０の後縁部４０ａは、車幅方向の中央部が最も前方に位置するように前方に凸に湾曲する。
　この構成によれば、左右に回動するアッパーカバー３１とフロントカバー３０の後縁部４０ａとの間の間隔を大きく確保できるため、アッパーカバー３１を回動させ易い。
　また、アッパーカバー前面４７は、前縁４７ａの後方に、車両側面視で延長線Ｌに対し前方に突出する部分として凸部５１を備える。
　この構成によれば、走行風Ｗは、前縁４７ａの後方で延長線Ｌに対し前方に突出する凸部５１に当たることで、上方側に流れる。このため、乗員側に流れる走行風Ｗを低減できる。 Further, when viewed from the top, the rear edge portion 40a of the front cover 30 is curved forward so that the central portion in the vehicle width direction is positioned furthest forward.
With this configuration, a large space can be secured between the upper cover 31 that rotates left and right and the rear edge portion 40a of the front cover 30, so that the upper cover 31 can be easily rotated.
Further, the upper cover front surface 47 has a convex portion 51 as a portion projecting forward with respect to the extension line L in a side view of the vehicle behind the front edge 47a.
According to this configuration, the running wind W flows upward by hitting the convex portion 51 projecting forward with respect to the extension line L behind the front edge 47a. Therefore, the running wind W flowing toward the passenger can be reduced.
