Abstract:
1. A lens barrel, comprising: a fixed frame having an optical axis; a rotary frame provided inside the fixed frame and configured to rotate about the optical axis relative to the fixed frame; a first frame provided inside the rotary frame and configured to move in an optical axis direction in a state in which rotation of the first frame about the optical axis relative to the fixed frame is restricted; an electronic component provided inside the first frame and configured to move in the optical axis direction in a state in which rotation of the electronic component about the optical axis relative to the fixed frame is restricted; and a flexible printed circuit board connected, at one end thereof, to the electronic component so as to extend to the fixed frame by way of a side of the rotary frame opposite to an object in the optical axis direction, and connected, at the other end thereof, to the fixed frame, wherein a gear part is provided at an outer circumferential surface of the rotary frame, and in the first frame, a first protrusion outwardly protruding beyond the gear part in a radial direction about the optical axis is provided at a position corresponding to the flexible printed circuit board in a circumferential direction about the optical axis on a side of the gear part opposite to the object in the optical axis direction.
