PROBLEM TO BE SOLVED: To provide a structure in which the entry of water into the inside of the structure is further prevented, and a lens barrel. ! SOLUTION: A structure 1 includes: a first member 11 having a first surface 11B; and a second member 15 having a second surface 15B facing the first member 11, and moving relative to the first member 11. One side of a gap between the first surface 11B and the second surface 15B is communicated with the inner space of a housing, and the other side of the gap is communicated with the outer space. The structure 1 further includes: an elastic member 20 extending from the first member 11 side to the second surface 15B side and having a contact part which slides on the second surface 15B while being in contact with the second surface 15B when the first member 11 and the second member 15 move relative to each other; and a water absorbent member 25 provided on the inner space side with respect to an elastic shield member 20 in the gap between the first surface 11B an |
