するレンズ鏡筒駆動装置。 It consists of a combination of a lens barrel having a photographic lens and movable in the optical axis direction, a base plate, a first yoke and a second yoke fixed to the base plate, a coil, and a plunger, and the plunger is activated by energizing the coil. An electromagnetic device that moves the lens barrel in the optical axis direction, a stopper that guides the movement of the lens barrel relative to the base plate, and a near point adjustment screw that finely adjusts the lens barrel position when moving toward the near point side, and a near point adjustment screw that moves the lens barrel. a shaft member configured to guide the lens barrel and bias the lens barrel in a direction opposite to the suction direction of the plunger by means of an elastic member; and a guide provided at substantially symmetrical positions across the shaft member and the optical axis of the photographing lens. The plunger directly drives the lens barrel, functions as a stopper when the lens barrel moves toward the far point, and further includes a mechanism for adjusting the positional relationship between the plunger and the lens barrel. A lens barrel drive device characterized by:
