ZOOM LENS BARREL

PROBLEM TO BE SOLVED: To provide a zoom lens barrel which can suppress abnormal sound, vibration, wiring peeling, etc. SOLUTION: A flexible printed wire 15 has at least one folded part 15a when extending from a helicoid member 1 toward a unit along the optical axis and a fitting plate 14 has a 1st beam part 14c sandwiched in the folded part 15a and a 2nd beam part 14d which is provided closer to a camera body side than to the 1st beam part 14c and supports the flexible printed wire 15 closely to the optical side, so even if the flexible printed wire 15 bends when a cam cylinder 4 moves toward a helicoid member 1, the 2nd beam part 14d can suppress the inward spreading of the bent flexible printed wire 15 at right angles to the optical axis, so interference between the bent flexible printed wire 15 and cam cylinder 4 which is possibly caused in the absence of the 2nd beam part 14d can effectively be suppressed.
