A hydraulic auto-tensioner includes a rod inserted in a cylinder having a bottom and containing hydraulic oil, and a hydraulic damper in the cylinder for damping the push-in force that tends to push the cylinder and the rod in the direction in which the rod is pushed into the cylinder. An oil seal including a dust lip on the inner periphery thereof seals an open end of the cylinder. A rose-shaped snap ring is formed integral with the oil seal.
