置ズレを生じさせるという問題点があった。[Problem to be solved by the invention] In the prior art shown in FIG.
Since the adhesive 5 for fixing the lens 1 inside the lens 1 is separated from the lens barrel mounting part 3 and the lens frame mounting part 4 that position the lens 1 in the thrust direction, the adhesive 5 hardens and fixes the lens 1 in the lens frame 2. During the process of fixing the lens l inside, there was a problem in that the lens I was lifted up in the thrust direction due to curing and shrinkage of the adhesive nose, resulting in displacement in the thrust direction.

、レンズ保持の部品点数を増加させるものである。In the technique disclosed in Japanese Utility Model Application Publication No. 58-168702, since the lens is held between the barrel part for positioning in the thrust direction and the large diameter part, the lens is held through the adhesive filled in the large diameter part. When holding the lens, the curing and shrinkage of the adhesive causes the outer peripheral surface of the lens to lengthen in the direction of the adhesive, causing it to float up from the barrel, creating a problem in securing the position in the rest direction. To solve this problem, it is conceivable to use a holding ring on the large-diameter side, but this increases the number of parts for holding the lens.

できなくなるという問題点があった。Furthermore, in the technique disclosed in Japanese Utility Model Application Publication No. 61-49319, the lens is fixed by ultrasonic welding to a synthetic resin retainer ring, so strong vibrations are transmitted to the lens, causing the frame attachment portion to collapse. In addition, there were problems in that the position of the lens body in the thrust direction could not be secured.
