HIGH-FRICTION SEAL FOR FLUID AND SHOCK ABSORBER

摘要

A high-friction seal for fluid, used for high friction sealing and having no problem of leakage of a working fluid from a fluid lip despite the fact of having a dust lip which can be used for a shock absorber for a suspension of a vehicle. The high-friction seal has the fluid seal lip (2) and the dust lip (1). The thickness of a working fluid film formed by the fluid seal lip (2) in an extension stroke is greater than the thickness of a working fluid film formed by the dust lip (1) in the extension stroke.
