Claims

[Scope of utility model registration request]

Corresponds to the amount of rotation of the magnification conversion ring in riflescopes that have a structure in which the zoom lens frame inside the upright tube built into the lens barrel slides in the approaching and separating directions to change the magnification by rotating the magnification conversion ring. do,
A cam cylinder that rotates and moves back and forth in the optical axis direction is rotatably and slidably attached to the outer periphery or inner periphery of the erecting cylinder,
The tip of the fine adjustment device is brought into contact with the inclined surface of a cam member having an inclined surface on the outer periphery of the cam barrel, and a spring body is attached to the lens barrel for constantly pressing the upright tube toward the tip of the fine adjustment device. What is claimed is: 1. A trajectory correction device for a rifle scope, wherein the cam member is mounted inside the cam member, and the inclined surface of the cam member is formed in a shape compatible with trajectory correction.
