Abstract: A shock absorber includes: a collar which is mounted on an outer circumference of a cylinder movable in the axial direction with respect to an inner tube in which a liquid is stored and supports one end of a suspension spring. The collar has: an annular mounting portion whose one end is supported by the cylinder; an annular sliding contact portion provided to be closer to the suspension spring than the mounting portion and in sliding contact with an inner circumference of the inner tube; a truncated cone-shaped body portion that connects the mounting portion and the sliding contact portion and has a hole formed to apply a resistance against a flow of a liquid moving inside and outside the collar; and a rib formed on an inner circumference of the body portion along the axial direction.
