Abstract
When a plurality of opening units is provided for each lens unit in order to adjust the inclination and eccentricity of a lens unit, the design of an imaging device may be constrained and the size of an imaging device may increase. In order to prevent this constraint, provided are a lens barrel, an imaging element support structure, and an electronic viewfinder that may adjust the inclination and eccentricity of a lens unit by using an insertion unit including an eccentric cylinder unit and a frame support unit including a through hole including a plurality of openings having different opening widths.

A lens barrel comprising:
- a cylindrical lens frame supporting a lens unit and having three or more groove units arranged in a circumferential direction thereof;
- a cylindrical frame support unit supporting the cylindrical lens frame and having three or more through holes formed in a circumferential direction of the cylindrical frame support unit to penetrate the cylindrical frame support unit;
- and
- three or more insertion units inserted into the three or more groove units via the three or more through holes,
- wherein a plurality of openings is formed at the three of more through holes,
- wherein the plurality of openings has different opening widths and are arranged in a thicknesswise direction of the frame support unit,
- wherein two or more insertion units among the three or more insertion units include,
- a concentric cylinder unit arranged concentrically with respect to a pivot axis of an insertion portion, and
- an eccentric cylinder unit arranged eccentrically with respect to the pivot axis of the insertion portion, and
- wherein one or more of the plurality of openings have an elliptical shape with a major axis parallel to an optical axis of the lens barrel, and one or more of the other openings have an elliptical shape with a major axis parallel to the circumferential direction of the cylindrical frame support unit.
