PROBLEM TO BE SOLVED: To provide an imaging device which can suppress displacement of an optical axis of a lens unit with a simple configuration and can reduce its size.SOLUTION: An imaging device comprises: an imaging element; a lens for forming a subject image on an imaging surface of the imaging element; a lens unit having a cylindrical mirror barrel which supports the lens and includes a male screw part and insertion part on the outer peripheral surface; and a cylindrical lens holder which includes a female screw part and holding part on the inner peripheral surface. The imaging device is configured to insert the insertion part into the holding part to hold the lens unit on the lens holder, and screw the male screw part into the female screw part to rotate the lens unit with respect to the lens holder and move in the vertical direction, and thereby perform focus adjustment.SELECTED DRAWING: Figure 1 |
