The present invention provides an imaging device that is possible to conduct a focus adjustment with a high degree of accuracy due to high accurate fit between a hanger shaft and a hanger shaft hole of a lens frame. The imaging device 1 has an imaging unit 2, an optical unit 4 comprising a lens 16 and a lens frame 17 which supports the lens 16 and has a hanger shaft hole 19, a chassis 3 on which a hanger shaft 12 is integrally formed to fit into the hanger shaft hole 19, and a drive unit 5 for actuating the lens frame 17 of the optical unit 4 in an optical axis direction. The hanger shaft 12 has a plurality of diameters d1, d2 so that the chassis side of the hanger shaft 12 is largest and the side apart from the chassis 3 becomes small. The hanger shaft hole 19 has a plurality of diameters d3, d4 which fit to the hanger shaft 12.
