The level is inside a level casing 72 formed on the upper wall of the reflector. The structure is such that the straight type bubble tube 80 is accommodated.

The level casing 72 is formed by a rectangular side wall 73 that is integrally formed with the reflector 4 and rises vertically from the reflector upper wall. At the upper opening of the casing 72, a lid 74 made of a synthetic resin having high elasticity such as U polymer or polyacetal having a bubble tube attached to the back side is fixedly mounted by means of a concave-convex lance engagement and a fastening screw. That is,
A side wall region 73a on the lamp front side of the casing 72 is integrated with the standing wall 4d of the reflector 4, a rectangular upper recess 73b is formed in the front side wall region 73a, and the front end of the lid 74 is vertically downward. A hook 75 is formed to project and engage with the recess 73b on the casing side. Further, at the front end of the lid, a pair of locking portions 76 are formed to extend at both sides of the hook 75 with a slit 76a therebetween. Then, when the hook 75 engages with the recess 73b while the engaging portion 76 is in contact with the upper surface 73a ₁ of the side wall region on the front surface side, as shown in FIG. 75 and the like elastically deform in a cantilever manner in mutually opposite directions, the front end of the lid body is prevented from coming off in the vertical direction, and is elastically supported in the vertical direction. Thus, between the front end of the lid and the side wall 73a on the front side of the casing, the concave-convex lance elastic member including the recess 73b for preventing the front end of the lid from coming off and elastically supporting it, the hook 75, and the hooking portion 76. A junction A is formed.

On the other hand, a screw insertion hole 77 is opened at the rear end of the lid 74,

Assemble the level 70 to the reflector 4 with the lid
This is done by attaching the bubble tube 80 to the 74 and assembling it in the casing 72. The lid 74 is integrated with the upper wall of the reflector 4 as the level 70 by first engaging the front end portion with the side wall 73a on the front surface of the casing in a lance engagement and then fastening the rear end portion with a screw. Generally, in this type of conventional spirit level,
Although the bubble tube is hardened with gypsum in the container and integrated with the container, in this embodiment, the level 70 can be assembled to the reflector 4 at the same time as the level 70 is assembled. It is like this. Moreover, since the fastening means on one side of the lid 74 and the casing 72 is a lance engagement, the level 70 can be assembled to the reflector 4 with only one fastening screw 78a. Then, when the reflector 4 is tilted in the vertical direction, that is, when the irradiation angle of the headlamp is at the vertical proper position, the bubble of the level 70 is adjusted using the fastening screw 78a so as to come to the zero scale position 82a of the linear scale 82. To do. The area 6b of the front lens 6 corresponding to the level 70 is also a non-step surface so that the inclination amount can be read from above the side edge of the front lens through the non-step surface.

Further, FIG. 9 shows a main part of another embodiment of the second inclination measuring device. In the above embodiment, the spring washer 78 is provided on the side of the level body 70 to which the lid 74 is screwed, but in this embodiment, instead of the spring washer 78, the casing 73 at the end of the lid body is used.
Step d between the mating surface with and the screw seat surface (see FIG. 9)
Is formed, and the rear end of the lid is elastically supported by utilizing the step d. That is, the pair of the bent extending portion 77a on both sides of the screw insertion hole 77 periphery of the lid end portion is protruded, when screwing the fastening screw 78a into the screw insertion holes 73d ₁ of the boss portion 73d, the bending extension A compressive force acts between the projecting portion 77a and the screw seat surface portion 77b, and the end portion of the lid body is elastically supported.

Next, a measurement procedure of the tilt measuring device performed when the headlamp is mounted on the vehicle body and a procedure of adjusting the irradiation angle of the headlamp performed thereafter will be described.

As a single headlamp, when the zero point position 62a of the scale of the rod member 54 of the first inclination measuring device 50 coincides with the reference line 52a position, the light distribution characteristic of the headlamp in the left-right direction becomes an appropriate position, and the second The light distribution characteristic in the up-down direction of the headlamp is set to an appropriate position when the air bubble of the level meter 70 which is the inclination measuring device reaches the zero point position 82a of the linear scale 82.

When the headlamp incorporating the first and second inclination measuring devices 50 and 70 is mounted on the vehicle body, the scale display of each inclination measuring device does not come to the proper position due to various errors. Therefore, it is necessary to adjust the scales of the first and second inclinometers to appropriate states.

As the method of adjusting the scale, in the first inclination measuring device 50, the vehicle body and the optical aimer are faced to each other, and the adjusting screws 20 and 30 are rotated to match the optical axis 1 of the headlamp with the axle. At this time, the reference line position 52a and the scale zero point position 62a do not match due to variations in the lamp mounting surface on the vehicle body side. Then, the support member 52 is pivotally operated by a driver and moved back and forth in the axial direction so that the scale zero point position 62a of the first inclination measuring device coincides with the reference line position 52a. In this way, when the irradiation angle in the left-right direction of the headlamp is at a proper position, the scale of the reference line position 52a of the first tilt side 50 meter is adjusted so as to display the zero point.

On the other hand, also in the level 70 which is the second inclination measuring device, when the headlamp is mounted on the vehicle body, the bubble position is the zero point position of the scale 82 due to variations in the lamp mounting surface on the vehicle body side.
May not match 82a. In such cases, adjust screw 30 (and tightening screw 78a if necessary).
Rotation is performed to adjust the bubbles to come to the zero point position 82a of the scale. In this way, when the vertical irradiation angle of the headlamp is at a proper position, the second level measuring device, that is, the level indicator.
The 70 bubbles are adjusted to display the zero point 82a of the scale.

After that, the user adjusts the irradiation angle of the headlamp. Then, looking inside the headlamp from above the upper side wall of the front lensize 6, the reference line position 52a of the first inclination measuring device 50 does not indicate the zero point position 62a of the scale, or the level indicator 70 which is the second inclination measuring device. Is the zero point on the scale
If there is a deviation from 82a, the amount of inclination of the lamp body in the left-right direction or the up-down direction, that is, the deviation of the irradiation angle of the headlamp in the left-right direction or the up-down direction can be read from these deviation amounts. And in this case,
The adjusting screw 20 or 30 is rotated, respectively, so that the scale zero point position 62a comes to the reference line position 52a in the first inclination measuring device 50, and the level indicator 70 which is the second inclination measuring device,
The bubbles are adjusted so as to come to the scale zero point position 82a. In this way, the irradiation angle of the headlamp in the horizontal direction or the vertical direction can be adjusted.

4e ₁ is formed. Then, a part of the light in the reflector 4 is guided to the outside of the reflector 4 through the opening 4e ₁ and is radiated to the side surface of the tilt measuring device 50. Therefore, the tip region of the support member 52 of the tilt measuring device 50 is illuminated brightly, which is convenient for reading the scale.

Reference numeral 4f is a standing wall that is located between the level gauge 70 that is the second inclination measuring device and the valve 41 and forms a part of the reflector 4. An opening is also formed at a position of the standing wall 4f that faces the spirit level 70. 4f
₁ is formed. The opening 4f ₁ opposed to the further opening 72a is also in a region opposed to the bubble tube side of the casing 72
Is formed, and a part of the light in the reflector 4 is guided to the outside of the reflector through the opening 4f ₁ on the reflector side,
Further, the side surface of the bubble tube 80 is irradiated with light through the opening 72a of the casing. Therefore, light is diffusely reflected on the surface of the bubble in the bubble tube 80, the visibility of the bubble position is good, and the reading of the scale is easy.

FIG. 11 shows a main part of still another embodiment, in which a half mirror region for guiding light to a level, which is a second inclination measuring device, is formed in a predetermined region of the reflector. That is, an opening 4f ₁ as shown in FIG. 10 is formed in the standing wall 4f of the reflector, and the half mirror 90 is integrated with the opening 4f ₁ by an appropriate means such as welding. The half mirror 40 is formed by vapor-depositing an aluminum coating 92 inside a transparent polycarbonate material having a shape matching the opening 4f ₁ of the reflector. The coating 92 is a thin film and reflects a part of light. The structure is such that the remaining light is transmitted. Therefore, in the embodiment described above, the position of the opening 4f ₁ for guiding light to the level 70 through the front lens looks dark, but this does not occur in this embodiment.
