The same reference numerals as those described above denote the same or equivalent parts. The front cowl 20 is formed of a thin plate member such as a synthetic resin, and the headlight unit 21 having the bulb 23 as a light source is inserted into the opening provided at the approximate center of the front cowl 20 from the back side. By mounting in such a manner, the lens as the light emitting unit is configured to be looked out of the front cowl 20. Further, when the headlight unit 21 is attached, there is no step between the lens and the front cowl 20, and both are formed so as to form a substantially smooth continuous surface. The appearance of the cowl 20 is enhanced, and the high-class feeling and merchantability of the motorcycle 1 are improved. However, as will be described later, when the optical axis of the headlight unit 21 can be adjusted vertically with respect to the front cowl 20, the left and right side surfaces of the front cowl 20 and the headlight unit 21 are adjusted by adjusting the optical axis. The gap 41 may become larger. The headlight unit 21 according to the present embodiment is characterized in that extending portions 40 are formed on both side surfaces in the vehicle width direction in order to reduce the influence of traveling wind due to the gap 41.

ヘッドライトユニット２１の上部には、車幅方向に細長いポジションライト２４が配設されており、無色透明のアクリル板等で形成されるウィンドスクリーン２２は、左右一対の前側取付ステー２８および後側取付ステー２９を用いてフロントカウル２０の裏面側に形成された４つのボス（図３参照）に固定されている。ヘッドライトユニット２１の下方側の左右に配設される前側方向指示灯３０Ｌ，３０Ｒは、車体前方側でフロントカウル２０と略面一な表面が形成されるように取り付けられている。また、フロントカウル２０は、その裏面側に形成された左右一対の取付ステー２６と、下端部に形成された取付ステー２７によって、不図示のカウルステーに取り付けられる。   A position light 24 elongated in the vehicle width direction is disposed on the upper part of the headlight unit 21, and a wind screen 22 formed of a colorless and transparent acrylic plate or the like is provided with a pair of left and right front mounting stays 28 and a rear mounting. The stay 29 is fixed to four bosses (see FIG. 3) formed on the back side of the front cowl 20. The front direction indicator lamps 30L and 30R disposed on the left and right sides of the headlight unit 21 are attached so that a surface substantially flush with the front cowl 20 is formed on the front side of the vehicle body. The front cowl 20 is attached to a cowl stay (not shown) by a pair of left and right mounting stays 26 formed on the back side thereof and a mounting stay 27 formed at the lower end.

図３は、ヘッドライトユニット２１が取り付けられた状態のフロントカウル２０の背面図であり、図４は、ヘッドライトユニット２１の単体の斜視図である。前記と同一符号は、同一または同等部分を示す。図３に示すように、ヘッドライトユニット２１の上部には、前記ポジションライト２４が収められる開口部２４ａが形成されている。また、開口部２４ａの左右には、前記ウィンドスクリーン２２の前側取付ステー２８（図２参照）に係合される前側ボス３２と、後側取付ステー２９に係合される後側ボス３１とが設けられている。また、前側方向指示灯３０Ｌ，３０Ｒの取付箇所には、ウィンカバルブを支持するソケットを通すための貫通孔３５が形成されている。なお、図中のＯ−Ｏ線は、バルブ２３の中心を通る水平線である。   3 is a rear view of the front cowl 20 with the headlight unit 21 attached, and FIG. 4 is a perspective view of the headlight unit 21 as a single unit. The same reference numerals as those described above denote the same or equivalent parts. As shown in FIG. 3, an opening 24 a in which the position light 24 is accommodated is formed in the upper portion of the headlight unit 21. Further, on the left and right of the opening 24a, there are a front boss 32 engaged with a front mounting stay 28 (see FIG. 2) of the windscreen 22 and a rear boss 31 engaged with a rear mounting stay 29. Is provided. In addition, a through-hole 35 for passing a socket that supports the winker valve is formed at the attachment location of the front direction indicator lights 30L and 30R. Note that an OO line in the figure is a horizontal line passing through the center of the valve 23.

ヘッドライトユニット２１は、前記バルブ２３を支持するハウジング３４に無色透明のレンズ２５を被せた構成とされており、ハウジング３４の背面側には、バルブ２３の取付部を覆うゴム製のカバー３３が取り付けられている。また、前記ハウジング３４の上部には、左右一対の支持ステー３６ａが設けられており、ヘッドライトユニット２１は、フロントカウル２０の裏面側に設けられた支持部３６において吊り下げられるように取り付けられている。これにより、ヘッドライトユニット２１は、支持部３６を中心に所定の範囲内で揺動可能、すなわち、上下方向の光軸調整を行うことが可能となり、ハウジング３４の下端部に配設されると共にネジ機構を内蔵した光軸調整機構３７によってその微調整を行うことができる。そして、前記したように、本実施形態に係るヘッドライトユニット２１においては、ハウジング３４の車幅方向の両側面に、薄板状かつ上下方向に縦長の形状とされる延出部４０が設けられている点に特徴がある。この延出部４０は、ハウジング３４の背面側の端部に形成されているので、フロントカウル２０の外方側から外観されることはない。   The headlight unit 21 is configured such that a housing 34 that supports the bulb 23 is covered with a colorless and transparent lens 25, and a rubber cover 33 that covers a mounting portion of the bulb 23 is provided on the rear side of the housing 34. It is attached. A pair of left and right support stays 36a are provided on the upper portion of the housing 34, and the headlight unit 21 is attached so as to be suspended by a support portion 36 provided on the back side of the front cowl 20. Yes. As a result, the headlight unit 21 can swing within a predetermined range around the support portion 36, that is, it is possible to adjust the optical axis in the vertical direction, and is disposed at the lower end portion of the housing 34. Fine adjustment can be performed by an optical axis adjustment mechanism 37 incorporating a screw mechanism. As described above, in the headlight unit 21 according to the present embodiment, the extending portions 40 that are thin and vertically long are provided on both side surfaces of the housing 34 in the vehicle width direction. There is a feature in that. Since the extended portion 40 is formed at the end portion on the back side of the housing 34, it does not appear from the outer side of the front cowl 20.

図５は、図２のＡ−Ａ線断面図である。前記と同一符号は、同一または同等部分を示す。図中の太矢印は、走行時における走行風１００の流れの一例を示す。前記したように、ヘッドライトユニット２０の車幅方向の両端部とフロントカウル２０の開口端部との間には、ヘッドライトユニット２１の光軸調整を行うために若干の隙間４１が必要である。このとき、隙間４１の車体後方側に障害物が何も設けられていないと、走行風１００が隙間４１からフロントカウル２０の内部に侵入してフロントカウル２０の整流状態に影響を与えると共に、走行時の空気抵抗が増したり、自動二輪車１のハンドリングに影響を与える可能性がある。また、走行風１００と共に雨等による水分が侵入すれば、電装機器等に好ましくない影響を与える可能性もある。これに対して、本実施形態に係るヘッドライトユニット２１では、車幅方向両側に張り出すような延出部４０が設けられていることで、隙間４１から侵入する走行風１００を大幅に低減することが可能となる。   5 is a cross-sectional view taken along line AA in FIG. The same reference numerals as those described above denote the same or equivalent parts. Thick arrows in the figure show an example of the flow of the traveling wind 100 during traveling. As described above, a slight gap 41 is necessary between the both ends of the headlight unit 20 in the vehicle width direction and the opening end of the front cowl 20 in order to adjust the optical axis of the headlight unit 21. . At this time, if no obstacle is provided on the rear side of the vehicle body in the gap 41, the traveling wind 100 enters the front cowl 20 from the gap 41 and affects the rectification state of the front cowl 20, and also travels. There is a possibility that the air resistance at the time increases or the handling of the motorcycle 1 is affected. In addition, if moisture from rain or the like enters with the traveling wind 100, it may adversely affect electrical equipment. On the other hand, in the headlight unit 21 according to the present embodiment, the extending portion 40 that protrudes on both sides in the vehicle width direction is provided, so that the traveling wind 100 entering from the gap 41 is greatly reduced. It becomes possible.

前記延出部４０は、ヘッドライトユニット２１を光軸調整の範囲内で揺動させてもフロントカウル２０の裏面側と接触せず、かつ隙間４１から侵入する走行風１００の量が大きく変化しないように構成されている。なお、前記延出部４０は、ハウジング３４に別体式の部品を取り付ける構成としたり、レンズ２５の端部に一体的に形成する構成としてもよく、その形状は、ヘッドライトユニット２１の形状や隙間４１の大きさによって適宜変更することが可能である。   The extending portion 40 does not come into contact with the rear surface side of the front cowl 20 even when the headlight unit 21 is swung within the range of optical axis adjustment, and the amount of the traveling wind 100 entering from the gap 41 does not change greatly. It is configured as follows. The extending portion 40 may be configured such that a separate part is attached to the housing 34 or may be formed integrally with the end portion of the lens 25. The shape of the extending portion 40 may be the shape of the headlight unit 21 or the gap. The size can be appropriately changed according to the size of 41.

上記したように、本発明に係る自動二輪車の前照灯装置によれば、ヘッドライトユニットの車幅方向両側に延出部を設けることにより、フロントカウルとヘッドライトとの間の隙間から侵入する走行風を低減することが可能となる。これにより、隙間から侵入する走行風のために自動二輪車の走行特性が変化したり、水分が侵入して電装機器等へ影響を与えることを防ぐことが可能となる。   As described above, according to the headlight device for a motorcycle according to the present invention, the extension portion is provided on both sides of the headlight unit in the vehicle width direction, thereby entering from the gap between the front cowl and the headlight.
