た。2. Description of the Related Art FIG. 1 is a perspective view of a conventional lens holder, and FIG. 2 is a front view of a conventional lens holder and a lens base. Only the lens holder is a sectional view. Conventionally, a lens base 2 having a male screw 1 and a lens holder 5 having a female 3 inside and having a female screw 4 engaging with the male screw 1 of the lens base 2 are screwed together,
In the work of rotating the lens holder 5 to adjust the position of the lens 3 and then adhesively fixing the male screw 1 of the lens base 2 and the female screw 4 of the lens holder 5, the lens holder adjusted as shown in FIG. The tip of the needle was inserted into the gap A between the lens holder 5 and the lens base 2, and the adhesive was applied and solidified to fix the lens holder 5 and the lens base 2.

一に塗布することができなかった。In the conventional lens holder structure, the total height of the lens holder and the lens base after assembly and the number of threads for securing the screwing strength of the lens holder and the lens base are limited. As a result, the gap between the lens holder and the lens base becomes small, and when the adhesive is applied to the gap between the lens base and the lens holder, the tip of the needle does not reach the screw part well, and the adhesive cannot be applied evenly. Also, with the female screw of the lens holder,
The adhesive did not permeate between the male screw of the lens base and flowed out to the outside, which deteriorated the appearance quality. Since only a high-viscosity adhesive could be used as a measure for reducing the outflow of the adhesive to the outside, workability was poor as compared with the case where a low-viscosity adhesive was used. Further, since the position of inserting the needle has not been determined, the adhesive cannot be uniformly applied to the threaded portion.
