Abstract
A lens barrel includes at least one lens, the optical axis of the lens; the first frame (the fixed frame) having the first restricting portion () and having an approximately cylindrical shape about the optical axis; the second frame () having the cam groove () and having an approximately cylindrical shape about the optical axis; the third frame () having the guide portion () which restricts inclination thereof with respect to the first contact portion () and the optical axis and having an approximately cylindrical shape about the optical axis; the drive arm () having a cam follower (), the second restricting portion () and the second contact portion (), and having an approximately arcuate shape constituted of a portion of a circular cylinder about the optical axis or an approximately plate shape; the guide shaft () for guiding the guide in a movable manner in the optical axis direction; and the spring (). The first restricting portion engages with the second restricting portion. The cam engages with the cam groove (). The drive arm moves approximately parallel to the optical axis due to the relative rotation of the second with respect to the first frame, the third is biased by the thus bringing the first contact portion and the second contact portion into contact with each other, and the third frame moves in the optical axis direction in an interlocking manner with the drive with the inclination of the guide being restricted by the guide.
