Abstract
A lens device includes: a lens frame that holds a first lens; a holding frame that holds the lens frame and that includes an elongated hole; and an eccentric roller that is disposed in the elongated hole and that is fixed to the lens frame. In a view in a direction of a rotation axis of the eccentric roller, an outer periphery of the eccentric roller is divided into four regions by a first axis and a second axis intersecting at the rotation axis, and the outer periphery of the eccentric roller has, in the four regions, one tangent along the first axis in a first region, one tangent along the second axis in a second region, one tangent along the second axis in a third region, and one tangent along the first axis in a fourth region.
