Abstract: A shock absorber includes a piston valve, a body valve installed at a lower side of a tube, a lower guide member installed between the piston valve and the body valve and including a lower through-hole through which the fluid passes, and a lower passing slit formed to allow the fluid to pass therethrough at a flow rate relatively lower than a flow rate at which the fluid passes through the lower through-hole, a mid-guide member having a mid-guide hole through which the fluid passes, the mid-guide member being disposed between the piston valve and the lower guide member and configured to close the lower through-hole when the mid-guide member is in contact with the lower guide member, a first elastic member interposed between the lower guide member and the mid-guide member, and a second elastic member interposed between the piston valve and the mid-guide member.
