PROBLEM TO BE SOLVED: To provide a lens barrel in which a wiring member can be freely arranged. SOLUTION: The lens barrel 1 includes: a stationary tube 20; a movable tube 90 movably provided in an optical axis direction with respect to the stationary tube; a holder part 92 fixed to the movable tube and provided with an opening part 93 passing through the optical axis; a lens group L1 capable of relatively moving in the optical axis direction with respect to the holder part; an actuator 110 generating drive force for performing relative movement of the lens group; a gear train 111 converting the drive output into relative movement of the lens group L1 and fixed to the holder part 92; a guide member 94 provided to the holder part and guiding the relative movement of the lens group; and a flexible wiring member 120 supplying electric power to the actuator. The actuator is disposed in one region ZA out of two regions divided by a straight line connecting the gear train on the holder part and the guide member disposed at the opposite side across the opening part with respect to the gear train. The wiring member extends from the holder part to the stationary tube side in the other region ZB side of the divided two regions. COPYRIGHT: (C)2009,JPO&INPIT |
