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 inner pivot is assembled by forcible fitting using elasticity of either or both of a pivot convex and a pivot concave without screw fastening;
• the outer pivot includes a plurality of elastic pieces disposed at a plurality of positions in a circumferential direction of a curved surface of either or each of an outer-pivot convex surface and an outer-pivot concave surface;
• and
• the outer pivot is assembled by the forcible fitting in the inner pivot and the plurality of elastic pieces elastically abut on an opposed curved surface.
