Abstract
PURPOSE: To improve the follow-up ability of an oil seal lip to the inclined movement of a piston rod by using a spirally wound spring material as a core member of an oil seal for a piston rod.
CONSTITUTION: A spiral spring 4 wound in conical cylinder form is used as a core member with its larger diameter side constricted against the inside of a cylindrical core metal 1' of an oil seal, a suitable seal rubber being baked on wrapping said cylindrical core metal 1' and the spiral spring 4 together to form an oil seal lip 5a and a dust seal lip 5b.
