<p>PROBLEM TO BE SOLVED: To provide a mechanism for enhancing shock resistance of a lens barrel without upsizing the lens barrel even when a notch portion is formed in a fixed barrel.SOLUTION: An imaging device includes: a device body 1; and a zoom type lens barrel 2 that is mounted on the device body 1 and varies photographing magnification by moving between a collapsed position and a photographing position in an optical axis direction. The lens barrel 2 includes: a fixed barrel 17 that is attached to the device body 1, and in which a notch portion 17a that penetrates from an outer peripheral portion to an inner peripheral portion is formed, a cam groove 17b is formed on the inner peripheral portion, and a projection 17c projecting outward in a radial direction is provided in the vicinity of the notch portion 17a of the outer peripheral portion; and a moving cam ring 8 that includes a cam follower 19 that engages with the cam groove 17b of the fixed barrel 17 and moves in the optical axis direction in rotation while the cam follower 19 follows the cam groove 17b. In the device body 1, a receiving portion 27a having a contact surface with which the projection 17c can be in contact when impact is imposed on the lens barrel 2 is provided while forming a gap between the receiving portion 27a and the projection 17c.</p> |
