Abstract
A sealing device has two sealing members. A first sealing member has a cylindrical mounted part adapted to be mounted to an outer member and an annular part extending radially inward from the cylindrical mounted part toward the inner member. A second sealing member has a sleeve adapted to be mounted to an inner member, a flange extending radially outward from the sleeve, and a cylindrical protruding portion made from an elastic material extending along the axial direction from the flange. Multiple retaining protrusions are formed on the inner peripheral surface of the cylindrical mounted part of the first sealing member are arranged at intervals in a circumferential direction. On the outer peripheral surface of the cylindrical protruding portion of the second sealing member, circumferential groove extending continuously in a circumferential direction is formed, within which the retaining protrusions are placed.
