［産業上の利用分野］
本発明は、鏡筒等の保持部材に接着剤によって固定する
、レンズ、平板ガラス、プリズム等の光学素子に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to optical elements such as lenses, flat glasses, prisms, etc. that are fixed to holding members such as lens barrels with adhesives.

As shown in Publication No. 95811, a lens as an optical element is dropped into a fitting part of a lens barrel, and the gap between the two is filled with adhesive using a syringe or a thin rod, and this is cured. I was trying to keep both of them together.

る恐れがある。[Problems to be Solved by the Invention] However, in the conventional method of fixing an optical element to a holding member using adhesive as described above, ■ the filled adhesive protrudes or flows out within the effective diameter plane of the lens. This may cause serious problems in terms of optical performance and appearance. ■ Wipe off the adhesive that sticks out above,
The increase in the number of man-hours required for cleaning and the occurrence of defects in optical elements and holding members that occur during this process also pose problems that cannot be ignored. In particular, when the optical element is made of plastic, the solvent resistance of the plastic is extremely low, so it cannot be cleaned, and if the adhesive protrudes, the entire product including the lens barrel will be considered defective. (2) Shrinkage force due to curing of the adhesive acts on the outer circumferential direction of the optical element, which may cause distortion in the optical element.

更に加えられる。■Also, as a means disclosed in the above-mentioned Japanese Patent Application Laid-open No. 195811, an adhesive injection port (No. 6 of the same publication) is provided on the lens barrel side.
(see figure), but in such a method, the injection port is perpendicular to the direction in which the optical element is assembled, so it is difficult to design the components disposed outside the lens barrel. The above limitations are significant, and there are additional drawbacks such as poor assembly workability.

Therefore, the trouble of wiping it off is completely eliminated, and the work of injecting the adhesive becomes extremely easy, and there are no design problems caused by the injection method, and furthermore, the problem of wiping it off is completely eliminated. This reduces distortion to the effective surface of the optical element due to the solidification of the adhesive, and multiple through holes for adhesive injection are provided, and by connecting these holes, air circulation is improved and the adhesive is injected more easily. It exhibits remarkable effects such as being able to fill without creating bubbles.
