装置。[Claims for Utility Model Registration] A focusing lens, a lens driving gear that is rotatably provided at a predetermined position in a lens barrel and drives the focusing lens, and a lens driving gear that uses power from a driving source to drive the lens. An autofocus lens barrel including a power transmission mechanism having a plurality of gears for transmission to gears, comprising: a single drive source unit holding the drive source and the power transmission mechanism; and a support for the unit. A vibration insulating member disposed in a hole of the plate, and a stepped screw that tightens the support plate to a fixed part of the lens barrel through the hollow part of the vibration insulating member, and the vibration insulating member and the stepped screw are provided. and supporting means for fixing and supporting the unit at a predetermined position within the lens barrel, and the stepped screw of the supporting means has a shaft portion with no thread formed thereon and a threaded portion formed on the tip thereof. and a threaded portion, the shaft portion being formed in a column shape that is thicker than the outer diameter of the threaded portion so that the boundary between the shaft portion and the threaded portion is stepped, and The vibration insulating member includes an insulating main body and a pair of flange parts in which flanges projecting in the radial direction are formed at both ends of the insulating main body, and the hollow part passes through the insulating main body and the flange. is formed so that the length thereof is longer than the length in the axial direction of the shaft portion, and the vibration insulating member is interposed between the stepped screw and the hole portion of the unit board to prevent vibration of the unit. A mounting device for a drive source unit of an automatic focusing lens barrel, characterized in that the drive source unit for an automatic focusing lens barrel is prevented from being directly transmitted to the lens barrel via the stepped screw.
