れ防止装置。[Claims for Utility Model Registration] (1) A movable frame that is linked to a cam frame driven by a motor drive unit and moves in the optical axis direction while being guided by a fixed frame, and is supported by the movable frame. In a zoom lens barrel configured to optically change magnification by displacement of the optical system, the optical system is
Or when displaced to the Wide zoom position,
A protrusion formed in the direction of the combined force of the stopper that stops the rotation of the cam frame and the drive force transmission portion of the cam frame by the motor drive unit is provided on the fixed frame and around the fixed frame. An optical axis shake prevention device characterized in that it is provided between a lens barrel fixing portion and a lens barrel fixing portion. (2) A fixed pin provided on a fixed frame contacts the cam of the cam frame, and this cam frame is driven by a motor drive unit to rotate and move in the direction of the optical axis. In a zoom lens barrel, the optical system is equipped with a movable frame that moves forward and backward in the optical axis direction in conjunction with the movement of the frame, and optically changes magnification by the displacement of the optical system supported by the movable frame. When the cam frame is displaced to the Wide zoom position, the cam frame is positioned at or near a position aligned with the direction of the resultant force of the force applied to the stopper that stops the rotation of the cam frame and the drive force transmission section of the cam frame by the motor drive unit. . An optical axis shake prevention device, characterized in that the fixing pin is provided, and the tip of the fixing pin is brought into contact with or fixed to a lens barrel fixing part provided around the cam barrel.
