Abstract: A damper includes: a piston configured to advance and retreat by receiving a force from another of a first member and a second member; a sliding member configured to slide on the piston as the piston advances and retreats; and a support member having a tubular portion and an insertion hole formed inside the tubular portion. The piston is inserted through the insertion hole. The sliding member includes a protruding portion protruding inward in a radial direction inside the tubular portion and configured to come into contact with an outer peripheral surface of the piston, an outer tubular portion disposed outside the tubular portion, and an extending portion extending inward in the radial direction from one end of the outer tubular portion and indirectly or directly coupling the protruding portion and the outer tubular portion.
