Abstract: A lens device includes a lens mechanism, a movement mechanism that includes a movement member moving the lens mechanism, and a braking mechanism that generates a braking force with respect to movement of the movement member. The braking mechanism includes a braking member that includes a pressing surface pressing a pressing target surface of the movement member, a support member that supports the braking member, and a pressing member that includes a pressing portion applying a pressing force to a first surface of the braking member. A contact portion between the pressing portion and the first surface is formed at a periphery of a recess portion.
