Abstract: PROBLEM TO BE SOLVED: To solve the problems in which in an imaging device having a lens unit, as flare measures by reflection light against a wall inside a lens barrel, conventionally a triangular uneven surface is configured to thereby attenuate reflection of unwanted light with reduction in plane surface, but since the uneven shape is fixed, when an angle of incoming light changes, an approach angle agrees with the triangular surface, a flare attenuation effect might be eroded, and further, the configuration of the triangular uneven surface is restricted to a limited range because of a mold structure, and as other measures against the internal wall surface, the uneven surface cannot be configured, and thus the other measures are insufficient.SOLUTION: In an imaging device having a lens unit, an unevenly-shaped bellows structural component having a triangular shape processed is arranged between a lens group and a barrel tube inside a lens barrel. Further, the bellows structural component arranged between the lens group and the barrel tube inside the lens barrel is provided with an extension/contraction structure, which in turn an angle of the uneven shape having the triangular shape processed can be changed.SELECTED DRAWING: Figure 5
