Claims

[Scope of utility model registration request]

In a lens assembly device in which a lens unit consisting of one lens or a plurality of lenses arranged in the optical axis direction via an annular spacing ring is fitted into a lens barrel so that their optical axes coincide with each other, and then fixed. , a pressurizing means disposed on the optical axis of the lens barrel and elastically pressurizing the lens unit in the optical axis direction; and the lens unit being elastically pressurized by the pressurizing means. and a fixing means for fixing the lens unit within the lens barrel, the optical axis of each lens of the lens unit is adjusted by applying the micro vibration. A lens assembly device characterized in that the lens assembly is configured to coincide with the optical axis of the lens barrel.
