摘要： A lens unit includes a lens barrel having an imaging optical system arranged therein and a movable unit having a movable lens, the movable unit being movable in an optical axis direction with respect to the lens barrel. The lens barrel includes a first member and a second member adapted to be coupled together in a coupling direction. Fixing pieces are provided on the first member and the second member, respectively, and fixing means is filled between the fixing pieces when the first member and the second member are coupled together. The respective fixing pieces are provided in positions at which a force is applied in a direction in which the fixing means is compressed by the respective fixing pieces when a force is applied to the first member and the second member in a direction in which the first member is released from the second member.
