Abstract
A shock absorber includes a reservoir between a cylinder and an outer tube, in which hydraulic liquid and gas are sealed; a middle tube between the cylinder and the outer tube; a connecting pipe in the lateral wall of the middle tube, which includes a tip end extending toward the outside of the outer tube; an opening in the outer tube, allowing hydraulic liquid to flow from the outside of the outer tube into the reservoir through the outer side of the connecting pipe; and a partition member in the reservoir, which includes a partition wall that configured to regulate hydraulic liquid's upward flow from the opening in the reservoir. The partition member is made of flexible resin or rubber, provided with a fitting hole, and fitted to the connecting pipe with interference with the connecting pipe inserted through the hole.
