Abstract
A piston with a piston rod coupled thereto is inserted in a cylinder, which sealingly contains oil. An oil flow generated by movement of the piston is controlled by a damping force generation mechanism, thereby generating a damping force. A separator tube is disposed around the cylinder, and the oil is transmitted to the damping force generation mechanism through a branch tube integrally formed on a cylindrical sidewall of the separator tube. The branch tube is tapered at the outer circumferential portion thereof with the outer diameter thereof reducing toward the distal end of the branch tube.
