Claims

[Scope of utility model registration request]

In a hydraulic optical axis adjustment device in which a connecting pipe section of a driving cylinder and a bushing mounting pipe section are formed by crossing each other, and the connecting pipe section is connected to an operating cylinder via a hydraulic pipe, the driving cylinder A mountain-shaped convex part is formed at the inner wall position where the connecting pipe part and the bushing mounting pipe part intersect. A hydraulic optical axis adjustment device designed to prevent this.
