Abstract:
1. A lens barrel comprising: a first lens group having one or more lenses; a first lens holding member holding the first lens group by surrounding the first lens group in a direction of rotation about an optical axis of the first lens group; a second lens group provided in parallel to the first lens group and having one or more lenses; a second lens holding member holding the second lens group on a photographing optical axis by surrounding the second lens group in a direction of rotation about an optical axis of the second lens group; and an adjustment mechanism provided on a first lens group side of the second lens holding member when viewed from the second lens holding member, and being capable of adjusting a position of the first lens holding member relative to the second lens holding member in a direction orthogonal to the photographing optical axis, wherein the second lens holding member is provided with at least three positioning parts on a first plane on the first lens group side and a sheet member attached to the first plane, the three positioning parts located at positions surrounding the second lens group and abutting on the first lens holding member in the photographing optical axis direction, the sheet member surrounding the three positioning parts throughout when viewed on a plane orthogonal to the photographing optical axis, and the sheet member is pressed against the first lens holding member in the photographing optical axis direction while surrounding the first lens group throughout, between the adjustment mechanism and the first plane when viewed in the photographing optical axis direction.
