By extending the vertical lens surface of the headlamp, and by providing support members for lamp aiming on both sides of the highly rigid lamp case, the accuracy of headlight aiming adjustment (optical axis adjustment) is improved. Improvement can be achieved. In addition, since the support member is covered by the cover members provided on the left and right sides of the headlight, the support member is not exposed to the outside, and the appearance is improved along with the extension of the lens surface.

  In the invention according to claim 1, in a headlight structure in which a lamp case that supports a bulb and has a reflective surface is closed by a lens, the lens has a substantially spherical shape in a side view, and an extended portion extended at an upper end of the lens. The surface of the approximately spherical shape is enlarged by providing it, and the extended part is made to follow the cover part extending from the reflective surface of the lamp case. And the design can be improved. In addition, by providing an extension that extends at the upper end of the lens, the substantially spherical surface can be enlarged, and the extension can be extended along the cover that extends from the reflective surface of the lamp case while further enhancing the external design. Since the light shielding function is provided, no cover is required outside the headlight, and the cover can be reduced in size and the cost of the headlight can be reduced. In particular, an extended portion is formed at the upper end of the lens, and the substantially spherical surface is enlarged, so that the lens can be formed into a large dome shape, and the design can be improved.

  According to the second aspect of the present invention, since the cover is extended to both side surfaces of the lamp case, the rigidity of the lamp case is increased, and the lens goes around both side surfaces of the reflection surface of the headlight.

FIG. 8 is a cross-sectional view taken along line 8-8 of FIG.
The headlamp mounting structure 60 is capable of swinging a headlamp 61 having a lamp case 63 having a reflective surface 67 and supporting a bulb 62 with a lens 64 and swinging about a support boss 71 (aiming axis) and a front cover. In a headlight mounting structure for a vehicle in which the lens is mounted in a state where the lens is exposed from the front opening 83 of the vehicle body cover 81, the lens 64 is formed to have a substantially spherical shape as a whole, and the upper edge 83a and the lower edge of the front opening 83 are formed. In the vicinity of the edge 83b, it can be said that the spherical portions 75 and 76 are formed on the lens 64 so as to substantially follow an arc centered on the support boss 71 (the aiming axis).

It is preferable to reduce the air resistance around the headlight 61 and to improve the design of the motorcycle 10 (see FIG. 1).
Therefore, the overall resistance of the lens around the headlight 61 is reduced by making the lens substantially spherical. In the vicinity of the upper edge 83a and the lower edge 83b of the front opening 83, the spherical portions 75 and 76 are formed on the lens 64 so as to substantially follow an arc centered on the support boss 71 (the aiming axis). And the gap between the front opening 83 and the front opening 83 is minimized. As a result, the design of the motorcycle 10 (see FIG. 1) can be improved, and water and dust can be prevented from entering the gap between the motorcycle 10 and the front cover 81 (the vehicle body cover) that covers the headlight 61.

The headlight 61 indicates that the support bosses 71, 71 (the back side 71 is not shown) are located above the optical axis C of the bulb 62.
The support bosses 71, 71 are positioned above the optical axis C of the bulb 62, and the headlights 61 are supported by the support bosses 71, 71 in a suspended state. The support of the lamp 61 can be stabilized.
The optical axis adjusting mechanism 65 reduces the load of the headlamp 61 at three points: the support bosses 71, 71 positioned above the optical axis C and the optical axis adjusting screw 78 positioned below the optical axis C. Since the support is dispersed and supported, the support of the headlight 61 can be further stabilized.

FIG. 9 is a sectional view taken along line 9-9 of FIG. 4. The headlamp 61 extends the cover 69 to both side surfaces of the lamp case 63, and has support bosses 71, 71 provided on both side surfaces thereof. This indicates that the supporting bosses 71, 71 also serve as aiming shafts.
The rigidity of the lamp case 63 is increased by extending the cover portion 69 to both side surfaces of the lamp case 63 and providing support bosses 71, 71 on the both side surfaces, respectively. The support bosses 71, 71 are provided on the lamp case 63 with increased rigidity, and the support bosses 71, 71 also serve as aiming axes, thereby improving the accuracy of the aiming adjustment (optical axis adjustment) of the headlight 61. .
Reference numeral 77 denotes a sealing member for sealing the lamp case 63 and the lens 64.

The operation of the vehicle headlamp mounting structure 60 described above will now be described.
FIGS. 10A to 10C are first operation explanatory diagrams of the headlight mounting structure for a vehicle according to the present invention.
3A shows a state in which the optical axis of the headlight 61 is horizontal.
In (b), the optical axis of the headlight 61 is tilted by the optical axis adjusting mechanism 65 as shown by the arrow a1, and aiming adjustment (adjustment of the optical axis) is performed.
In (c), the optical axis of the headlight 61 is further inclined as indicated by an arrow a2.

3A to 3C, the spherical portions 75 and 76 are provided on the lens 64 near the upper edge 83a and the lower edge 83b of the front opening 83 so as to substantially follow an arc centered on the support boss 71 (the aiming axis). For example, the gap between the lens 64 and the front opening 83 is not changed by the aiming adjustment. That is, the gap is constant. As a result, the gap between the lens 64 and the front opening 83 can be minimized, and the design of the motorcycle 10 (see FIG. 1) can be improved.
Although the optical axis C is adjusted so as to be directed downward from horizontal as shown by arrows a1 and a2, it is also possible to adjust the optical axis C upward from horizontal.

  FIG. 11 is a second operation explanatory view of the vehicle headlamp mounting structure according to the present invention. The headlamp mounting structure 60 has a substantially spherical shape by providing an extension 74 extending at least the upper end of the lens 64. By enlarging the surface and extending the extension 74 along the cover 69 extending from the lamp case 63, it can be said that a light-shielding treatment for blocking the light of the bulb 62 (see FIG. 8) has been performed.

For example, the cost of the headlight 61 can be reduced if a light-shielding treatment can be performed on the lens 64 without using a special member.
Therefore, by providing an extension 74 extending at least the upper end of the lens 64, the substantially spherical surface is enlarged, and by extending the extension 74 along the cover 69 extending from the lamp case 69, the light shielding treatment is performed on the lens 64. To reduce the cost of the headlight 61.
Then, an extended portion 74 is integrally formed at the upper end of the lens 64, and by enlarging the substantially spherical surface, the lens can be formed into a large dome shape. As a result, the design of the front part of the vehicle can be enhanced.
As shown in the figure, the driver M does not become obstructed even though the lens 64 of the headlight 61 faces upward.

  In the embodiment, as shown in FIG. 3, the lens 64 is formed in a spherical shape. However, the spherical shape may be any generally spherical shape (overall substantially spherical shape).

  The headlight structure of the present invention is suitable for a motorcycle.
