An imaging device has a lens group; a lens barrel for holding the lens group; a base member for holding the lens barrel; an imaging element; a securing plate that faces at least a portion of the base member in a state wherein the imaging element is secured; and a coil spring for pressing the lens barrel to produce a state wherein a male threaded portion of the lens barrel is pressed against a female threaded portion of the base member.

A tilt correction unit includes: an inner frame, inside which an optical unit is held; an outer frame surrounding the inner frame, with a gap formed between the inner frame and the outer frame around an entire perimeter of the inner frame; an elastic part which is disposed between the outer frame and the inner frame and elastically supports the inner frame inside the outer frame; a rotational movement support part that connects a part of an outer peripheral surface of the inner frame to a part of an inner peripheral surface of the outer frame; and a drive unit that comprises a magnet and a coil disposed opposite each other with a gap therebetween, wherein the inner frame is driven by the drive unit and rotates about the rotational support part, in a plane perpendicular to the optical axis of the optical unit.

A barrier device of the present invention includes a cover defining a front aperture, a base defining a rear aperture, an annular gap formed between a rear end face of the front aperture and a front end face of the rear aperture, a barrier member movably provided through the gap between a closed position and an opened position, and a seal member sealing the gap. The seal member is provided over an entire circumference of the clearance and formed such that, when the barrier member is in the opened position, the seal member seals the gap with a part thereof being in contact with the barrier member, and when the barrier member is in the closed position, the seal member deforms to make contact with a surface of the barrier member. This enables the barrier member to open and close smoothly, and reliably prevents penetration of dirt, dust, moisture or the like through the gap.
