与し得る。C. Effects of the invention As described above, according to the invention, a lens covering the opening of the case is connected to a synthetic resin lamp case having a reflection surface for the bulb formed on the inner surface using a lens fixing screw, and In a motorcycle lamp mounting structure in which the outer surface of the lamp case is connected to the vehicle body frame with case fixing screws,
The inner surface of the lamp case has a first boss portion into which the lens fixing screw is screwed, and the outer surface of the case has a second boss portion into which one of the case fixing screws is screwed. Since both bosses are arranged on substantially the same axis, the second boss does not protrude from the inner surface of the lamp case, and therefore the effective area of the reflective surface provided on the inner surface of the second boss does not protrude from the inner surface of the lamp case. It is no longer reduced by the second boss portion, and a wide reflective surface can be secured. Moreover, since the second boss part is not on the back side of the reflective surface, the wall thickness of the lamp case on the back side of the reflective surface can be formed uniformly at each part. It is possible to prevent distortion or deformation of the reflecting surface due to stress. Furthermore, since the screw holes provided in both boss portions can be machined in one screw hole machining step, this can contribute to improving the work efficiency.
