Abstract
A shock absorber includes: a metal cylindrical outer tube; a rod inserted into the outer tube, the rod being capable of moving in the axial direction; a bump cushion attached to an outer periphery of the rod that protrudes from the outer tube; a synthetic resin bump stopper formed in a cap shape and fitted to one end in the axial direction of the outer tube, the bump stopper being configured to be abutted by the bump cushion during maximum compression; and a sacrificial corrosion part disposed between the outer tube and the bump stopper, the sacrificial corrosion part being configured to contact a metal surface of the outer tube. The sacrificial corrosion part is made of a metal having a higher ionization tendency than the outer tube, and thereby corrosion of members is suppressed.
