<p>PROBLEM TO BE SOLVED: To provide a sealing device which can suppress the intrusion of muddy water or the like into a clearance between an outer member and an inner member, and can reduce restrictions in setting a protrusion length of a protruding part.SOLUTION: A sealing device 1 attached to an outer member in order to seal a clearance S1 formed between an inner member 20 which relatively and axially rotates and the outer member 30 comprises: a core metal 6 fit into the outer member; an elastic member 7 tightly adhered to the metal core and having lips 71, 72 and 73 which slide-contact with the inner member; and a rubber-made protruding part 70 which is formed further outside in the radial direction than the lips in a state of being tightly adhered to the metal core, and protrudes to the outside in the radial direction or the outside in the axial direction. The protruding part is formed so as to be higher in hardness than the lips.</p> |
