PROBLEM TO BE SOLVED: To downsize a lens unit and reduce costs of the lens unit. ! SOLUTION: In a lens unit, a link mechanism is configured to couple a support body to a driven body, and the link mechanism comprises: a first link member; and a second link member. One of a thermal expansion coefficient of the support body, a thermal expansion coefficient of the driven body, and a thermal expansion coefficient of the first link member and the second link member is different from both or one of remaining two thermal expansion coefficients. A first direction heading for a second rotating shaft from a first rotating shaft of the first link member is non-parallel to a second direction heading for a fourth rotating shaft from a third rotating shaft of the second link member. !
