View angle adjustment mechanism in view device

A view angle adjustment mechanism in a view device, the view angle adjustment mechanism being configured to support a view element tilting section holding a view element by a tilting support section via at least two concentric pivots having different diameters, the pivots including an inner pivot and an outer pivot, so as to be capable of adjusting a view angle of the view element, wherein:

• the view element tilting section includes a view element holder holding the view element;
• the inner pivot and the outer pivot are formed between the tilting support section and the view element holder;
• the view element holder and the tilting support section are joined to each other via the inner pivot;
• the outer pivot has a structure in which an outer-pivot convex surface formed at the view element holder and an outer-pivot concave surface formed at the tilting support section are slidably fitted together;
• and
• the outer-pivot convex surface is formed in an outer circumferential surface of an outer-pivot convex surface-forming annular wall formed at a back surface of the view element holder in an integrated manner.
